Tank-slapper on a Hyobag 250

[hmurphy]

G'day! Today while riding over the Rimutakas, I went around a corner and my rear wheel came out from underneath me! I didn't come off or anything but the bike bit back real hard in an attempt to high side me. I pulled over to find that my rear wheel was SOAKED in oil!! Dad and I then noticed that there was oil leaking from something that looked like a big fat overflow tube. Does that make sense!!? I don't think bikes are designed to have an overflow tube infront of the rear wheel! Oh, and the gearbox oil was not over filled.

We then stopped at the top of the takas to take another look (we were heading north). We decided to carry on cautiously to get the oil to ware off my tire. As we were heading down the other side (still heading north) I got on to a straight where I was cruising at 100km/h. Nothing stupid, it was a straight where you could go a lot faster than I was going! The handle bars bounced then started to thrash like crazy, smashing my hands in to the tank on both sides. I just rode it out, keeping the bike straight and no acceleration or brakes. The bike stopped having a fit at me then I pulled over again. I decided to ride home slowly which ruined my ride.

What the heck is wrong with my bike!? It is a 2008 Hyosung GT250R (a couple of months old) with 9,900 kms on the clock. Any advice?

Would a bike that has suspension for racing or something be better? Would I be better off on a ZXR250 or CBR250RR or something? See below. Would this bike make sure I don't get bounced around on reasonably quick runs over the takas?

The ONLY thing holding me back from owning an r6 is my damn restricted licence. I do nearly 1000kms a week of riding. I ride my dads CBR1000F as well so I have had experience on bigger bikes, as well as a lot of dirt biking.

Thanks guys (sorry, this is a bit of a novel)

Warranty? Take it back to the shop and tell them what you just told us. Something is really wrong there.

I have only managed to provoke a headshake on my 650 once - cornering, I leaned it well over at about 140 clicks, and there was a rise in the middle of the corner.. I came over the rise and down quite firm and she did about four good sized headshakes and never did it again.

For it to slap you like that, I would say that near highside had pinched or tweaked the frame or steering out of shape.

Bloody good save btw. Glad you are ok. Would have thrown many learners. BTW, if you have that much experience, try for an exemption.

Steve

[Ixion]

You say that you ride a CBR1000, and that the "ONLY thing holding me back from owning an r6 is my damn restricted licence". And you are asking these sort of questions?

Ever wonder what that experience might have been like at R6 speeds?

Give up Mr Katman, it's an impossible task. leave it to Mr Darwin, and Gene-O-Klene (in the giant economy size - evolution you can see)

[RantyDave]

Oh, hey man - I was on the Triumph that stopped. Glad to hear you got home OK.

First off, you didn't go home that slowly :) IMHO you may want to consider laying off the Rossi for a while, particularly if the bike is being a bit of an arse - nobody actually enjoys reading "rider down" threads mmmkay. Also, try using more countersteering and less movement. And when you do move, I'd say the idea is to move your centre of gravity over rather than just your shoulders - i.e. move your butt. That being said, if you really want to know how to ride well you shouldn't be asking me.

Now, the Hyobag. Is it now outside it's warranty period? It certainly felt like your rear shock has gone, and the earlier Hyo's (at least) had a reputation for failing in exactly the same way. BTW, I've also seen one (possibly overfilled) dumping oil all over the rear wheel. And, much as though we love them, that bike had also just been for a service at TSS. However, in your case, I'm pretty sure it's the shock. The suspension was *way* spongy IMHO. Hopefully it's still under warranty - take it back to the shop and look more pleading and less annoyed.

You have every right to be annoyed, BTW.

Best of luck,
Dave

[Headbanger]

Pity, I was looking forward to Mr Ixions informed thoughts on the issue at hand.


edit.

My bad, Looks like Ixion read the situation pretty damn well, Crazy. I'm going back to my corner.

[CB ARGH]

To be honest, I don't know much about bikes. But I am sure that it isn't normal for a bike to have an overflow tube for oil to pour into the tracks of the wheels - that's insane.

Good on you for saving the slapper too, good work there man. I seriously reccommend that you take it back under warranty, however you may be waiting for some time to get it fixed if there are any problems.

EDIT: Just remembered that you were looking into other bikes. I would say to stay with the Hyosung and spend the money on a bigger bike when you can. However if you really want a different bike, the CBR250RR goes very well, even though it is the first road bike I have EVER rode, I feel like it was built just for me.

[hmurphy]

Cheers for the escort! I was kind of hoping the bike would kick again to be honest haha.
I went at a reasonable pace to get the bike to kick again to 100% prove something was wrong. The pace was quicker than most cars over the takas but was controlled. I was hoping it would shimmer again in the front or have the rear wheel do something funny. The bike rode home fine however. Perfectly normal. Too much ass off seat means you ride twisted too and that means that your pelvic line is not parrellel to the bikes centre line resulting in the bike leaning over just as far as it was in the first place. Often it is best to get your head out around the mirrors and drop your shoulder around corner and relax arms. This keeps the bike more upright around a corner. These are all tips that I have been taught by a motorcylce expert for road riding. I forget his name, sorry. From Lower Hutt.

The rear suspension is very soft, I agree with you there. But this seems to be how they are designed. It is no softer than when I first bought it! These Hyobags are often described as "bouncy castles" or "trampolines" and these descriptions are not far from the truth at all!! I have been bounced around plenty on it.

Yeah I applied for an exemption but they are only removing the restriction on hours I can ride.
An r6 is a crazy fast bike! I have seen every single r6 video on youtube and a hell of a lot of other bike videos on youtube too. What really appeals to me about the bike though is the handling. My handlebars wont lash out and bounce around on a quality bike like an r6.

Thanks for all your help guys, keep the comments coming if you have any. Cheers

[CookMySock]

The rear suspension is very soft, I agree with you there. But this seems to be how they are designed. It is no softer than when I first bought it! We got two of them, and they are hard as a rock. I reckon your one is rewted.

Steve

[johan]

Have you checked tyre pressures?

[hmurphy]

Really!? I have read on a bunch of forums that the Hyobag GT250R has soft as hell suspension so it is more comfortable for the learner riders who only use the bike for commuting.

But with what you have said, I will talk to TSS tomorrow and ask them about my suspension. But it is always good I have found to talk to other riders who aren't mechanics but have possibly had experience with these sorts of things. So far kiwibiker members have been a great help with the many problems my damn frickin hyobag has given me.

Cheers

Have you checked tyre pressures?

Absolutely!! I take care of my bike quite damn well, but it seems to not give a shit about me! I keep the chain tensioned correctly ALWAYS and I use correct non fling chain lube.

Cheers!

[FJRider]

G'day! Today while riding over the Rimutakas, I went around a corner and my rear wheel came out from underneath me! I didn't come off or anything but the bike bit back real hard in an attempt to high side me. I pulled over to find that my rear wheel was SOAKED in oil!!...

Not one or both seals gone, in one, or both, rear shocks... would explain "fluids" on the rear wheel ...???

[CookMySock]

Really!? I have read on a bunch of forums that the Hyobag GT250R has soft as hell suspension so it is more comfortable for the learner riders who only use the bike for commuting.The front is quite soft with not enough spring rate. The rear is way too hard with way too much spring rate, unless you are two-up. I have seen the rear wheel airborne on straight smooth road. The suspension is the biggest let down of the hyos I reckon.


[...] many problems my damn frickin hyobag has given me.Ah yeah they have their issues. Two of our hyos we have never touched. The other one had quite a few things. They are great to learn to corner on though ay.. ;)

Well done on keeping yourself upright today despite the mess that is your bike and the way you ride. Frankly mate, having a rear tyre SOAKED in oil and cautiously cruising at 100kmph leading to a tank slaping good time ride leads me to believe you actually need your head examined. You finally decide to ride home slowly, and that ruined your ride after slip sliding and tank slapping????

Get your bike to a shop first opportunity and get it sorted!



First off, you didn't go home that slowly :) IMHO you may want to consider laying off the Rossi for a while, particularly if the bike is being a bit of an arse - nobody actually enjoys reading "rider down" threads mmmkay.

Sorry to pick bits of your post, I actually liked what you said after this as well, but this suits my Mom stance better :cool:

Hahahahahahaha I will give it a go mate

[henry]

The rear suspension is very soft, I agree with you there. But this seems to be how they are designed.

I had one of these and the back end was hard as fuck. Sounds like your shock shit it's oil over your back wheel. A knackered rear end might also explain the head shake.

PS. Be thankful you weren't on an R6 when this happened.

[BiK3RChiK]

I think henry is right on this one. Dood, tell the dealer to sort it out. Sounds like you have a dud one. I'd get rid of it asap...

[portokiwi]

Its just so lucky you didnt crap out going down the hill on those bends.
Good riding mate:Punk:

[hmurphy]

Just got it back from dealer. The rear suspension didn't shit itself afterall!! There is a mystery oil ejecter on my bike. The shop is running a test to check that oil isn't shooting out one of the breather tubes. One thing is for sure though, oil (and lots of it) has spewed out from somewhere on the bike. Finding where is going to be the next problem.

I might be changing the rear suspension settings or getting some quality suspension put on the bike. A stearing dampner is another thing that I might be putting on the bike. These are all things that I just discussed with the dealer and mechanic. To be honest, I just don't trust the bike anymore.

[hmurphy]

PS. Be thankful you weren't on an R6 when this happened.


Hell yeah I agree mate!!! Would have been a one way highside to Auckland on a powerful machine like that. But would a 2008 r6 be shitting oil over the rear wheel..? Probably not! Well.... I would sure as hell hope not!!

Cheers

[BiK3RChiK]

It just seems that there's the odd one which comes out that has issues. I think this happens with any equipment. You'll always get the odd dud. Get rid of it as soon as you can. I don't think it is a reflection on the Hyosung. I've heard of other new bikes having issues too... and cars... It seems to me to be a fact of life.

[RantyDave]

The rear suspension didn't shit itself afterall!!
It's *supposed* to be like that?

I might be changing the rear suspension settings or getting some quality suspension put on the bike.
LOL on both counts there, I'm afraid. For one, *can* you change the suspension settings? Maybe preload but after that I'm afraid it's almost certainly stuck on "crap".

Decent suspension would be a waste of money, unless you managed to score some second hand/cheapie forks and dampers from somewhere. It will make no difference to your resale value, not one drop.
[/QUOTE]These are all things that I just discussed with the dealer and mechanic. To be honest, I just don't trust the bike anymore.[/QUOTE]
The dealer and mechanic would really quite like to discuss anything other than them finding a non-fucked bike for you to ride.

Dave

[hmurphy]

Yeah I agree with you. It's not worth pouring money into a bike like this. My dad and I are running through the options...:

-tune bike differently
-buy stearing damper and rear suspension
-buy a different bike, e.g. a ZXR with low kms or CBR-RR (all 250cc)
-buy a bigger bike and be done with it, e.g. A FREAKING r6 BABY!!

There is a lot to discuss though so I shall see what happens. Cheers for the help guys! Catch you on the roads

[BiK3RChiK]

Mate, you should be getting this sorted under warranty! There is something seriously wrong with your bike and the next time could be the last time you ride it. I think the shop is giving you the run-a-round. Go to a different bike shop and get another opinion.... I'd be too scared to ride it.

[avgas]

hey drongo, get yourself some clues here ok.
- If you cant handle a lowly GT250 then forget about an R6 for the short term.
- Oil res on a 4 stroke.........something is fishy - take it back to dealer to sort......they have to, that is why you have a warranty.
- Who the hell told you that an R6 won't tank slap? its slaps harder and faster than your GT......it has clipon bars dumbass....

Ixion you are right - the only thing this squid is missing in jandals.

[CookMySock]

Listen up - if the bike will tank slap in a straight line at 100k/hr then something is seriously wrong with it. Stop blaming hyosung and get the fault fixed. No one elses GT250R does this. Sounds to me like you have a steering head bearing problem, or bent front or rear suspension - probably by that near-highsider.

If you try to sell it on trademe (or anywhere), you will have to fess up about the (dangerous!) fault, and then its worth little or nothing. Geez its under warranty man - go stand on them about it.

no.. it's a hyobag problem. CHEAP shit is cheap shit.. no matter what colour you paint it.

He has a point - it is a Hyosung, after all.

Oh they will, it's definitely not hard to get into a tank slapper on an R6, that why so many people put steering dampers on them.

COmpletely agree, unless the shop gives you a reasonable trade-in. Then they can sort out the warranty issues directly.

Ixion you are right - the only thing this squid is missing in jandals.

Geez mate your a firey bastard arn't you?!

I can handle a GT250R, believe me. I have never come off and I have done nothing on it to prove that I can't ride it well!! So where did that comment come from? Am I riding it badly because oil shitted out the back on to my rear wheel and all over my bike and caused a near high side WHICH I brought back? I ride DRZ400 bikes often at my uncles farm off road on tricky stuff so I am used to slides, but an oil slide is something completely different.

SQUID!!??!? I wear leathers when I ride, boots and gloves. If I was riding "Stupidly" and "Quick" then the oil would have taken the rear wheel right out from underneath me OR the near high side would have actually been a high side. Believe me, I could have gone MUCH quicker around the corner if I wanted to.

The tank slapper at 100km/h was waaaaaayyyyy out of the ordinary. I could have been going 130km/h on the hyobag if I wanted (and still be cruising on that straight) and it bounced everywhere on a dead straight line. I am quite damn sure a 2007 or 2008 r6 would have gone over that with no worries! Hell my Dad's 1990 CBR1000F went faster on the straight than me with no tank slapping action and his bike is over 18 years old!

So what I am saying is, the r6 wont randomly tank slap on simple straights like my Hyosung is. I NEVER SAID that it doesn't tank slap. Shit, if you were being a big enough dickhead on New Zealand country roads (speeding, wheelies etc.) I am sure you could get mostly ANY bike to tank slap. So buddy, read the tread properly before you start accusing me of being a "SQUID" or a shitty rider or a "dumbass".

Other than that guy have a laugh because he thinks I am a "dumbass", the comments have been helpful. I have been talking with the dealer and mechanic and the problem with my Hyosung will be rectified. I value my life and I don't want to be on a leasurly cruise or on a bit of a burn over the takas and have another tank slapper or oil leak.

Cheers for the help and discussion guys and gals

[hmurphy]

Oh they will, it's definitely not hard to get into a tank slapper on an R6, that why so many people put steering dampers on them.

I could imagine mate!! But would it tank slap at 100km/h on a dead simple straight? My dads 18 year old bike will sit at twice that on country roads and not even slightly try to put the rider in to a tank slap. My Hyosung would try to do it on the first pebble on the road!
I would definately have a damper on a high power machine like the r6 too. I never race or go for high speed all the time, but I do like to have the bike nice and low so a quality bike that wont spew oil over my rear wheel and a damper for reassureance would be quite nice right about now!

Cheers mate!

[bert_is_evil]

You're right it definitely wouldn't do that - sounds like you have some major issues with that Hyosung! I'd defintely go for the trade it and let the dealer sort it out under warantee option asap if there is one.

[hmurphy]

Yep! That warentee will save my ass! Literally. Oh and my wallet. There are enough holes in that already.

[nodrog]

have you thought that maybe there is nothing wrong with your handbag, and you may have just hit something on the road like a stone/uneven pice of tarmac/dip in the road/low flying wood pidgeon/etc?

ive had many high quality motorcycles (yes better than this magical R6 of which you speak) and have had tank slappers on all of them, which have all been caused by external elements (the best being when i ran over the neighbours cat)

if it happens once or twice forget about it, if starts to happen repeatedly burn it and claim the insurance money.

[jrandom]

it does now, Harsha sent me the ones of his fxr150

[hmurphy]

Hahaha!! I like the r6 for a lot of reasons already, and I havn't had a chance to ride it yet! I will line up the best of the 600 supersports and decide on one in a years time.

Yeah I absolutely thought it was just stuff I was hitting on the road, and I still think that! But it seems that the bike is already worn out from the 4 or 5 that I have had and is doing it much easier than usual. Poor thing, I liked a lot about the Hyosung to be honest. But I don't like it much now that it wants me dead what with all the oil splurting from the bike on to the rear tire.

[nodrog]

get your head stem bearings checked, they could be fucked.

[xwhatsit]

To be honest, I don't know much about bikes. But I am sure that it isn't normal for a bike to have an overflow tube for oil to pour into the tracks of the wheels - that's insane.
I don't know about the GT250R (quite a lot of modern bikes I see have the crankcase breather piped into the airbox, I've seen it labelled in workshop manuals as relating to US emission laws or summat), but my 250RS, C50 and plenty of other bikes I've seen run the crankcase breather straight down and out the bottom of the frame just before the swingarm U-bend -- right in front of the rear wheel.

The amount of oil that comes out the breather should be miniscule anyway, unless it's drastically overfilled or the rings are scuppered (combustion chamber blow-by, pumps oil out the breather).

I know TSS can do no wrong by most people here, but, er, how did they check the shock wasn't fecked? You say it's been like pudding since new, yet all these other people are saying the rear-end is quite solid on the GT250R? Could be they just pushed down on the seat, it seemed OK-ish, and wrote you off as a nincompoop squid talking bollocks (understandable if you pulled the `Ima Rossi and R6s are just like soooooo coool' spiel on them too :shutup:).

Oil has to come from somewhere. If it hasn't cropped up again on your back wheel, are you sure you didn't ride through something? Also, as others have said, you didn't just hit something on the road to cause the head-shake? With apologies to Hanlon, `never attribute to your bike that which can be adequately explained by yourself' :innocent:

[bull]

Been having a read over at Korider (http://www.korider.com/forum/index.php) and couldnt bring up any similar issues that you raise so it looks like yours is likely to be the guinea pig.

I had my 2006/7 GT250R from TSS for 16000km(1yr) trouble free and its happily still going with its new owner.

Once it gets sorted please post up what the official problem was and how it was remedied for future GT250R owners.

[johan]

Does the front wobbles when you take your hands off the bar?

This is what the service manual suggests:

Steering oscillation.
1. Loss of balance between right and left front suspensions.
2. Distorted front fork.
3. Distorted front axle or crooked tire.

Wobbling front wheel.
1. Distorted wheel rim.
2. Worn-down wheel bearings.
3. Defective or incorrect tire.
4. Loosen nut on axle.

Was it really oil on the rear tyre, or was it brake fluid?

Leakage of brake fluid.
1. Insufficient tightening of connection joints.
2. Cracked hose.
3. Worn piston and/or cup.

[hmurphy]

Will do!! Cheers mate.

Also it's wicked to see the amount of riders on this forum who really know their stuff! All your ideas are being written down and taken to TSS. There was a hell of a lot of oil that came out of the bike on to my rear wheel (also splattering everywhere). And this happened about 3 weeks ago but was much minor the first time, but enough to give me a decent tail kick!!! (also happened on the takas).

I can take my hands off the handle bars at 100 - 110km/h and coast the bike right down to 20km/h and the front wheel does not wobble.

Haha I like to go reasonable quick, but not Rossi styles!! I actually don't like the idea of racing on dodgy New Zealand roads where horse shit and sheep on the roads are as common as mud. That's what the track is for! I am going to a track day at Taupo in November (all booked!).

[henry]

If you're going to be dumping oil on the road every time you go out, stay the fuck away from the hill. It's hard enough to get up there in one piece as it is. And I'm not trying to be funny.

[lostinflyz]

You'll probably find the bike mechanic at the local shop will only be able to look things over and spot obvious issues. If there was mountains of oil (a wee bit of oil spreads easily all over tyres easily) then it should be obvious but just only a smallish amount might be harder to spot.

Tracing all the breather overflow pipes should be pretty easy to do and find if one is possibly spewing oil. could someone (or has??) someone had the motor out or fiddled with the hoses and connected one up wrong. (airbox off, radioator fix up, boredom?)

But that being said if it dumped oil once it should do it again. usually. a once off oil leak is probably more concerning as thats rather different. that may be a shocky spewing its oil out. Ive found if you ride a bike with a soft rear end and stiff front they tend to slap quite alot, everywhere.

But either way sort it out before you ride it. for everyones sake.

btw: if you lean into a corner with your shoulders and dont shift your arse you get a curved spine. In order for said spine to be parrallel with the bike, the bike must be curved. If this is the case it will be the source of your problems.

[avgas]

Please educate me, how does clipon bars relate to tank slappers?
lower riding position, arms closer to total bike - when issue occurs requires more effort due to torque effect to combat issue.
Hyosungs bars are good for learners and well spread - also rising position is more upright allowing for less "race" issue and more "riding bike" style.
its all geometry.
I didn't mean to be so hard in my last post - its obvious to me that your fairly new to all this. However what i say is true in regards to bike size is true.
I would be puddle with teeth if i didn't progress slowly up the bike chain.
From what i can see when i messed around the Hyosungs is that they share alot of the same issues - cost cutting.
Hyosung is an OK bike, the Jap bikes are just about OK.
I just replaced by footpeg bracket on my fazer......i didn't break it or anything - alloy just got a hairline fracture and all of a sudden i had no rear brake. Crap alloy. Also google "GSXR frame fractures" or "ZXR engine blown" and you see they all have faults.

[DarkLord]

Yeah man that's no good at all. I've got into a couple of tank slappers, mainly from hauling ass up over a hill and been going a little too quick and come down a little harder than expected, but 3-4 quick slaps and it's over.

For that few k's on the bike, I would absolutely take it back to the shop. Rear tyres soaked in oil never ends well..........

[hmurphy]

btw: if you lean into a corner with your shoulders and dont shift your arse you get a curved spine. In order for said spine to be parrallel with the bike, the bike must be curved. If this is the case it will be the source of your problems.

Yep I usually move my ass off the seat but only to the point where I am parrallel with the bike. I have had knee down a few times like when I was following my dad up the takas, trying to keep up with his cbr1000. Although it was/is a great rush, I didn't like pushing hard at the end of the day on those roads. I just enjoy a 60% - 70% run on the takas, sometimes slower! I just love to ride.

Couldn't agree with you more, I do not want to dump oil on the road and get other riders in trouble. I would rather my bike's diarrhea just throws me off and not anyone else!

The amount of oil that came out was substantial, hell it suprised my dad when he saw it and he was a grease monkey most of his life! Until he became a computer programmer haha.

Cheers

[Rev DJ]

Just want to echo Bull's comments - it will be good to know what the technical/mechanical findings are in this instance. It is definitely an unusual incident/s and would be useful for all riders to learn from this...

And well done on catching and riding out both!! :niceone:

Cheers

DJ

[hmurphy]

Cheers mate! I am heading to the shop now so I will see what they have to say.

[flyingbrick]

what did they say?

[hmurphy]

Hey! The plan is to put a bottle over the engine breather (NOT an overflow tube, a breather) and see if oil is finding a way to spurt out of there when the bike is getting a bit of a hammering from the rider, i.e. flicking her around a bit (takas) etc. Also, a damper is going to be fitted to the bike. So, the next short while will be a testing process. Hopefully there will be some conclusive/positive results.

I will be in touch about what happens, whether we find out what is wrong and/or I come off the bike. I have been pretty cautious on it since Sunday, but she is now sitting in my garage exactly on 10,000kms (I got home from Wellington at 9,995 and took it out for a quick 5km blat haha). It is nice to see the bike got there in one piece (same with me), but I must admit that it hasn't got there in style!

[CookMySock]

Did they not take it for an open-road ride ? No sign of the tank slap ?

Steve

[johan]

Take it to the next trackday where you can analyse it over the same corners over and over and understand what's going on.
Doing it over the takas is only foolish.

My bike tank slap slighty occasionally. But I usually know where and how it happens. Leaned over, coming out of a particular corner on the gas, the front skimming over the ground, going over a few peculiar bumps in second gear, at Taupo track. In third gear it's fine.

Did the shop offer to setup the suspension for you, instead of band aiding a maybe poor geometry with a steering damper?

[hmurphy]

No they didn't take it for a ride, but they have offered suspension setup etc. and steering damper. I am taking it to a track day in November at Taupo so I shall see what happens there when I give her a bit of shit. This weekend I should hopefully find out if the oil was coming from the engine breather or not. Weather permitting though (need dry roads to go a little quicker).

[Rev DJ]

Thanks for the continuing updates - fascinating. :yes: Surely the source of the oil should be easy to trace? Either the rear damper is leaking/empty or the sump has less oil than before?? You have noted that you always maintained your bike so any change in oil level should be easily seen?? (I'm thinking of installing a catch-tank/bottle for the oil breather tube on my bike just in case...)

Keep the updates coming...

DJ

[hmurphy]

The oil seems to just spurt out in one giant surge when it is in a lower gear and hovering just below redline and when I am throwing her into corners and uphills and downhills. Like on the Rimutakas. So tracing the oil is a bit tricky. But the oil is definately coming from the bike! No doubt about that. Cheers

[Rev DJ]

It sounds like a compression leak at high rpm?? It'll be interesting to see the results of a comp-test...

DJ

[Rev DJ]

Bump - any update hmurphy?

[hmurphy]

Handle bar broke off. No damage to bike. Frickin' crap quality and I am sick of it. The bike is an amazing commuter! But it is NOT a sports bike and should NOT be treated as one. By this I mean it can't handle a 4 hour long ride through corners and country roads. Bikes should get excited when they see the takas approaching.... my Hyosung get nervous and pisses itself all over my rear wheel and shakes in the front.

The bike is being traded in, no more Hyosung for me. I am already on a new bike. Much MUCH better quality bike. Took it over the takas today and it felt amazingly safe. The bike just stuck to the road where the Hyosung would have bounced and jittered.

I recommend the Hyosung for cheap and comfortable commuting, but it is not a sports bike.

[raftn]

So what did you get? The R6? Glad you have seen the light ......Hybags serve there purpose, but i dont think generally they are very well built.

[roy.nz]

I had a hyo gt250r and the pipe at the back is a breather pipe which is normal on cars and bikes and the oil is most probally due to a an overfill which isn't uncommon.
Ride Safe highsides hurt, I KNOW......

[hmurphy]

Haha I might share some pics sometime soon of my new bike... but for now all I will say is that it is a Yamaha

[CookMySock]

You might let people know where the bike went, or what its rego is, so someone doesnt end up with your buggered bike killing them.

Steve

[hmurphy]

Absolutely mate! The bike will be advertised correctly. I will only recommend it to people who need a good commuter pretty much. Cheers for your concern!

[CookMySock]

The bike will be advertised correctly. snort, make sure you don't leave off the bit about it wanting to tank slap in a straight line at 100k's.

Steve

[Rev DJ]

Thanks for the update hmurphy :done: Have there been any conclusions as to the cause of the oil-dump and tank slapper problems? DJ

[CookMySock]

Have there been any conclusions as to the cause of the oil-dump and tank slapper problems? DJNup. He's gunna ditch it - serious fault unresolved. Re-read above - he's going to "recommend it to people who need a good commuter." Cool ay !

Make fucking sure you don't buy it for your teenage daughter to lear, er, kill herself on. I think this one should go international - what say you ? I think the bike should be deregistered, pending an engineers report.

I asked for this deathtraps' rego, so we can track it, but no reply was forthcoming. Can anyone identify this bike ?

Steve

[hmurphy]

The bike has been said to look like a sports bike, but not ride like one. In other words it is a great commuter, very comfortable and nice for long cruises but is not suited for riding with a bit of assertiveness, especially over cruddy-ish surfaces. It has a great engine and set up, but to get the real quality of a great sports bike I was told to upgrade from the Hyosung.

I still recommend the Hyosung for commuting and for gentle rides. But I am much happier on a bike that will be more than happy when shitty roads are thrown at it. The new bike has a steering damper, excellent suspension, very sturdy frame, bigger tires and ergonomics that are suited for twisties!!

[hmurphy]

WOAH!! No need to fire all guns yet mate!! The bike is in my garage and getting a new handle bar and is going for a full inspection before selling again as well. When or IF it makes it on to trademe, it will be advertised with full history. It is more likely that it goes back to the shop when it is fixed up.

There is no way I want to sell this bike to someone and have them get hurt. I never got a PM from you either. I would have replied straight away!

[bert_is_evil]

I don't think a bike that goes into a tank slapper for no apparent reason at 100 clicks could be considered a great commuter

[hmurphy]

It is going to be assessed by the shop and if they deem the bike safe, then I MIGHT sell it myself. Otherwise it goes back to the shop to stay/rot.

[xwhatsit]

Methinks a variation on PEBKAC is needed -- PEBHAS?

[Rev DJ]

It is going to be assessed by the shop and if they deem the bike safe ...

hmurphy - good thinking.:clap: I am sure you will do the right thing by the next rider - or the shop will.

I hope you dont mind me pressing about the cause as it seems to be a very unusual mixture of issues. It leaves us trying to figure out what happened to trigger this whole saga?? The information that either you or the shop can glean about what mechanically/technically happened can show how future incidents could be prevented. This is valued and appreciated.

Cheers DJ

[hmurphy]

No worries mate!

It seems that the oil may have been overfilled and while the bike was flipping left and right and up and down through corners on the rimutakas, the excess oil found a way to surge out an engine breater and on to my rear tire.

[nico]

No worries mate!

so,, i take it nothing will be covred under warranty?? as mentend eairler you do all servicing ie over filling oil? i asume the dealer would use this as a loop hole to aviod any thing at all costs
i may be wrong. so is it fixed and what is the work from it's inspection.

and what bike you riding now ill have to watch out for some crazy bastard flying past me up the takas again

[flyingbrick]

snort, make sure you don't leave off the bit about it wanting to tank slap in a straight line at 100k's.

Steve

Cant you leave the guy alone? He's in a shitty bloody situation and is doing the best he can. I feel damn sorry for his misfortune; you need to stop being such a cynical fuck... pretty tiring tbh.

[hmurphy]

Nah I always took it to the shop for its 4000km service! I wanted to keep it under warrenty. Was expensive though!! I do 4000km in 4 weeks.

I am riding a blue and white bike. Haha that is all I will say for now. But don't worry about me flying past you!! I don't like the idea of racing up the takas. I just ride the takas leasurely. Hooligans pass me on the hill.

[xwhatsit]

I am riding a blue and white bike. Haha that is all I will say for now.

[hmurphy]

xerxesdaphat - I found that quite funny! Hahaha!!! I am afraid I own a Yamaha and I have wet weather gear to stop me from road rash and getting wet and I have leathers for the weekend rides!! I keep it safe, but if I ever get caught like this guy on a bike like that then please make fun of me like someone has done to him!!

And as for you DangerousBastard, I am disappointed with the quality of your behaviour. I have done ABSOLUTELY NOTHING wrong so far. In fact, I was smart enough to get off the bike in the first place. I am not going to dump this on another person. Your attitude needs some adjustment, you are way out of line if you are going to accuse me. I sought out the help from various sources (e.g. kiwibiker, mechanics etc.) so what makes you think that all of a sudden I am stupid? It is people like you that are out there to spoil places like this, and quite frankly you are putting me off kiwibiker forums if I am going to have to deal with immature people such as yourself.

If you are that concerned, address the matter in a mature manor. Rev DJ is a perfect example of a guy who is also concerned about the bike and the safety issues it would impose on a new owner/rider. However, he has simply asked for some clarity and can understand that so far my head has been screwed on. I have done the right thing, I am doing the right thing and I will continue to do the right thing.

I am going to ask you to not post on this thread anymore please, you are clearly concerned but you are addressing the issue very unprofessionally. Unless you can change your attitude. Other than one or two guys feeling like they have to bag on me,

thank you ALL for your concern

[Ixion]

So , just to recap here. 'Someone' overfilled the bike with oil, which (gee, surprise) caused some of the excess to vent out the breather.

And the 'tankslapper' turned out to be a momentary headshake when hitting bumps at speed.

But the Hysosung fails the all important squidley test, so the "pissing oil everywhere for no reason" and "tankslappers down the straight" could be used to convince dad that a learner on an R6 was the lesser evil.

Mission accomplished, I'd say.

It's all good, I get a commission on the Gene-o-Kleen ("Evolution you can see". In the squid sized bottle) sales.

[CookMySock]

Bew heww heww for yeww hmurphy. The thing you will find about KB is that its a public forum, and people can post where they see fit. If you are disappointed about this, then go elsewhere by all means. If you think the little bit of attention from me is painful, wait until the day the full force of the KB retard team is unleashed upon you. That will make your eyes water.

Look, All I'm askin from ya, is the rego of this bike, so I (and others) don't end up buying a bike with a very dangerous hidden fault, without it being subject to an engineers report. See? Not hard is it ? So just post the rego plate.

But you won't, will you. Because then you will have to pay for the engineers report. So quit squirming and bleating and fess up.

Yes yes, I know you just wanted to ask for help, and yes I know that has backfired on you, but hey thats life, bro. Next time think carefully before you tell everyone whats wrong with your bike before you sell it.

Steve

[hmurphy]

Firstly, I never asked for my Hyosung. My parents didn't like the first bike I was on. It was generally faulty (1987 CBX250). It needed over $500 of repairs to pass a WOF. So my parents went out and HELPED me buy a safer bike which was the Hyosung to be more reliable etc. When this failed my mum was angry with the quality of the Hyosung (after 3 months and 10,000kms) and went and got me something of the SAME PRICE but is a trusted brand.

I am allowed to be riding the bike I am on now as well, so no biggy there either. Also, I have been riding since I was 11 years of age. That is 8 years of mostly off road riding on DRZ400 dirt bikes. I know how to control a bike.

I am not going to post the rego for you because I don't trust you mate. If the bike is parked on the street somewhere (and yes, I know you live just around the corner from my place) how am I supposed to know you wont see it and trash it? I am already going to pay for a full inspection of the bike and if the bike shop is happy then there is a good chance I will leave the bike with them to sell. They have to deem it safe first.

The inspection includes a long ride to get the bike to slap after it has had adjustment up front. I have had 2 really big slappers on that bike, my hands were literally slapping the tank. I have had a couple smaller ones. The oil was not overfilled by me.

I asked you not to post because it appears I am not the only one who is sick of you. "you need to stop being such a cynical fuck... pretty tiring tbh.".

Mate, if you are going to be a dickhead when I have come on here for help, then I wont come on here for help again. It is a shame because there are a lot of you who had a lot of really good things to say!! It is sad that this friendly community you have here on KB is spoiled by a few guys.

If you guys have any more questions or suggestions, feel free to post. I am clearly not an idiot or at all trying to put anyone in danger by selling my bike to them, so there is no need to accuse me of anything. Cheers

Ur an asshole. Dont like my opinion? You can fuck off.

[RantyDave]

but hey thats life, bro.
Unfortunately DB has caused me to be conflicted. On the one hand I can't really go through his last dozen posts infracting every one just because he's a total and inescapable tool. On the other hand I just don't give a flying fuck at the moment and it would be an astounding use of ten minutes of my time.

I actually met this lad, y'know. Standing, pissed off, next to his fuxx0r3d hyobag wondering wtf to do next. It was the first time I saw someone actually kick their bike in frustration. He's a bit squiddy, I'll grant you that. With any luck he'll come off at a track at some point, hurt himself really badly, be fundamentally OK, and spend the rest of his days contemplating how much worse it would have been if a truck had been coming the other way. Or a fucking cheese cutter. But he's just a lad, with a bike, he deserves our support and without it he might become a statistic.

The real failures in this story are TSS, who sold a slightly squiddly learner an utter death trap then, by the sounds of things, completely fucked the maintenance into the deal. And Hyosung, manufacturers of said death trap. Hello? The handlebar broke off? It dumps excess oil on the rear wheel? ... and I see we have one losing it's chain (http://www.kiwibiker.co.nz/forums/showthread.php?t=82224) today too.

Hyobag's are official utter sacks of shit. Most people (by which I mean more than half) get one that works, but many people don't. It's unfortunate, then, that they get sold to learners. Thankfully Kawasaki now make a "looks like a sprotsbike" 250 so the number of squiddy "new bike" learners on decently made bikes should actually go up, not down.

Best of luck, Mr Murphy (I don't recall your first name, sorry man), and there is no need to disclose your bike's reg number, history or otherwise ... other than to put the word "Hyosung" in the description and hope it acts as a warning all of it's own.

Dave

[hmurphy]

Yeah I was frustrated that I had to ride such a crappy machine!! I gave it a kick because I spent so much time and money keeping her in good condition and maintaining her to then get treated like shit by the bike!! Very frustrating!

I haven't been riding for all that long on road (since half way through March of this year) but I have done near 20,000kms of riding since then
(mostly just fun rides over takas and up to my uncle's farm). I have been riding for 9 years though on motorcross bikes but I have never competed in motorcross. It sucks that I am able to give DRZ400's a good thrashing, crash them etc but NEVER have any problems with the bike. And I treated the Hyosung so well but it kept shitting out. From MY experience, I am only going to stick to brands that have been around for years and years.

My mate got himself a CBR250RR recently and I gave that a bit of a ride too. Compared to the Hyosung it felt much safer (handling wise) and was a bit more exciting with the extra 15 horsepower. It is a shame that they don't still make them because they would have been a great machine if they were around today (for brand new). I didn't get an old 4 cylinder beast (e.g. cbr250rr, zxr, fzr) because if they were to prove unreliable (easily possible with old old bikes) then getting parts could be a mission.

Catch you guys around, maybe at the top of the takas! I am always up there

[Cr1MiNaL]

Inconceivable!

I don't use words like that anymore :sleep: I use my style to impress.


Raj is that you?

Hello :clap:


I bet your trumpy doesn't have MotoGP brakes.

My Limited Edition R6 comes with monoblock usd carbon fiber disks that are unbridged and floating. What do yours have?

[jrandom]

I don't use words like that anymore

I do not think, however, that that word means what you think it means.


My Limited Edition R6 comes with monoblock usd carbon fiber disks

Your carbon fibre brake discs are upside down, eh?

:lol:

[Cr1MiNaL]

Your carbon fibre brake discs are upside down, eh?
:lol:

Indeed. Valentino's 2009 M1 will no doubt use the same technology. It helps air into the vents hence allowing the disk to cool faster :niceone:

[jrandom]

Indeed... It helps air into the vents

You'd want to be careful to always keep the bottom half of the wheel on the ground, of course, lest your upside down disks get rotated right way up and lose their cooling efficiency.

[Cr1MiNaL]

Of course.

[jrandom]

Of course.

Actually, what you need is that wondrous technology that boi racer cars have which enables the wheels to turn while an extra layer of chrome bits on the outside of the rims stays stationary.

If your R6 had something like that, your style would be unparalleled.

I also think your bike needs more blue and purple LEDs.

[Gubb]

I also think your bike needs more blue and purple LEDs.

...but but but... More LEDs means less room for Flames.

MAKE UP YOUR MIND MAN!

There's only so much "Cool" that one bike can handle.

You could, like, pick out the flame shapes with LEDs.

ZOMG, the awesomeness, it asplode my mind!

[Camshaft]

ive owned an 07 hyosung gt250r for 2 years and it has never given me a spot of trouble, i hav it wound out in every gear, take it for up to 3 hour country rides never realy goin below 120 except to corner.
just regular services and it performs fine.
are problems reali that common or do ppl just complain to much

[george formby]

Cheers for the escort!

The rear suspension is very soft, I agree with you there. But this seems to be how they are designed. It is no softer than when I first bought it! These Hyobags are often described as "bouncy castles" or "trampolines" and these descriptions are not far from the truth at all!! I have been bounced around plenty on it.

Yeah I applied for an exemption but they are only removing the restriction on hours I can ride.
An r6 is a crazy fast bike! I have seen every single r6 video on youtube and a hell of a lot of other bike videos on youtube too. What really appeals to me about the bike though is the handling. My handlebars wont lash out and bounce around on a quality bike like an r6.

Thanks for all your help guys, keep the comments coming if you have any. Cheers
I would'nt bet money on that!

[Odakyu-sen]

I would'nt bet money on that!

Yup. The stock 2001 R6 (the first one with the LED arse) is a head-shaker. Polite journalists describe the bike as "nervous"; personally, I would describe its head shaking as "grand mal" (with apologies to any epileptics reading this).

[Sidewinder]
