New guy to Buckets

[mossy1200]

Theres a Aprilia RS250 front guard on Trade Me, but I guess its not carbon enough for ya? :innocent:

Its a rsv1000 showa fork set up. im not sure the sizes are the same. The showa forks are 53mm. Ill see if they match. I sent the fork guy a email to see if he still has the guard. He has also just sent the clipons to me but they havent arrived yet.

Rsv aprilai 1998-2003 and tuono 2003-2005 fit these forks.

Got sliders sorted.

[husaberg]

Im using the aprilia triple clamps and aprilia axel so its stock width for a aprilia. Its the tripple clamp shaft and crush tube and axel spacers I have modified. Forks are still Aprilia stock spacing.


ok but the guard firs around the front wheel which is 250 sized?

[mossy1200]

Simon from down South has this guard at 120 which hes just confirming is for my model or a damaged carbon one for 50 that needs work.

[mossy1200]

CBR250 17inch front wheel with 90/80/17 tire so I would assume the higher wall slimmer tyre will fit ok.

YEAH but won't it will look a little odd if its a wide wrap around?
Any way go for the carbon it's a bucket after all.:shifty:
It will look sweet once you get some Magnesium Honda RS250 wheels for it.:yes:

Yes. Im not sure ill get the wheels. They are on special for 1500usd at the moment but I need to get everything else sorted before I push my luck with the wife on that item. I tried telling her a good motor could cost 2k and she gave me angry secks but not a go ahead on the engine.

The mille guard side fit on the 120tyre is a very close fit so idd say 15mm each side gap. The guard isnt a full type so should look ok. the carbon one the guy has is so damaged idd need repair it and paint it black. I might opt for the new carbon one from the UK depending on the freight price which he will need send me. At least idd have a bling looking good handling slow bucket racer.

What if I was to get the 50 carbon damaged and take 10mm out of the centre the whole way down and repair it narrowing it and put 5mm spacers on each mount? that could work. Sounds like a god idea or not?

What disk is that?
great to know there is also another source of 3 spoke 2.5x17 as well.
I see You a have a brembo. What is that from.... sliding 2 pot?4 pot.
zip ties very bucket chic:2thumbsup.
Mossey now wheres your 6 pot AP.

question is, what does a front guard actually do on a bucket?

I dont think mine needs anything more than a sliding 2 as its a slow bike and with the heavy Aprilia front ill prob do stopies all the time.
Guard keeps you from stubbing your face on the tyre if you go over the forks. I assume your saying we dont have to have one.

I was just thinking what they actually do on a bucket i never ran one cause i couldn't be arsed.
The road bike yeah stops the water slash etc but it was a serious question.

Stop the face hitting the wheel.... i guess so but you would have to pick you crashes.I normally slide into the bales "gracefully" myself.
the only other one excluding the streamlining effect on a faster bike was to stop rocks and shit bashing the rad.
Obviously not an issue with air cooling.

Trainspotters aronaks (got me)
so its a fixed disk?

Got myself the wrong brembo on TM i didn't know they had 2 different stud spacings and the pads are different to the spare pads and part i already have will be harder to fit as well bugger.


Dammit ... now my secret is out! The front guard keeps water from splashing from front wheel .... :innocent: Ohhh, and it looks cool, and only cost $32 incl freight. :woohoo:

yeah but the water other than getting the bike wet is it really an issue.
I am guessing you are still going to get wet anyway plus the bike will too.
Yeah it does look cool though

[Kickaha]

What spacing do you need 40mm or 65mm?

Im feeling your pain. It took me 8hrs to make and fit plates and wheel spacers to get almost no drag on the disc from the pads. Had to move the caliper 15mm inwards to get it mounted. A bolt on 6 pot would have just needed spacers as my disc is same size as the mille lol.

[husaberg]

What spacing do you need 40mm or 65mm?

I think 40mm. The one i have got i am pretty sure is 65mm. (Guzzi i think.) Def 65mm shit its a bloodly left too and no pins as well.
i can run and out an measure. The spare pads i have are all for RS125 Honda NX4 and 5's but why are the pads to different (Bloody Italians)

The Aprilia spacing is 65mm post pic and how much did you pay?

[speedpro]

It's easier to spin up a disc spacer of the exact thickness than make caliper adaptor plates. The benefit also is that the caliper doesn't end up trying to twist around the fork with being mounted so far inboard.

[husaberg]

$40 but its a left and no pins.:angry2::Oops::shutup::scratch:
It's nice and Gold though and its looks like i will have to rob the cr500 for its one. Actually i should measure up the adapter on the CR500.
I see there is a guy selling adaptor plus brembo for a NF4 on Ebay but too dear for me.

That would have been a good idea but the nissan spaces are 80mm and the aprilia forks are 65mm and also the angles were incorrect on the mounts. The caliper mount lower is infront and below the aprilia mount and the top is further away from the fork to make it line up.
with the rsv1000 front axel being 25mm and the design being for a large bike im hoping to have no twist issues.

Nice. I have fork mounts on both sides and could have flipped the wheel and reversed the tire. :pinch:

That's something interesting as well why do most (ok a lot) bikes with single disk have the caliper on the left when the MC is on the right so they could have made the routing shorter? ESP dirt bikes whats up with that?

if its any good to ya you can have it for $40

If its ok ill run the next round and PM you if im not happy with the way the bike stops. Even with a short 2 finger brake lever and rubber line soon to be braided it was stopping good before the fork conversion. I have a angry wife now also she has worked out the $400 budget just hit 2.5k so far plus the guard at 250 if I get that and a carb at 150 also. I just dont feel brave enough to mention another part unless you take paypal,visa or paynow and she wont see the purchace for a while.

Backing up a few posts I've run both with and without front guards in the rain and the difference in the amouNt of water is astounding, enough difference that with the front guard you have better visibilty and can concentrate more on not falling off than wiping your visor.

I think with the bt39s the water would come up in a nice straight line for my face due to the centre tread line being straight through the tire centre. Its a good spot for sponsors name also. Where does one get a bucket racing sponsor from?:confused:

I went to my old sponsors who were paying $700 per round on tires and they just looked at me and said "Buckets??".
I think they may have been thinking of keg racing or something similar.
I tried to explain with corp sponsorship i could have 37+ hp and get a top 10 finish in b grade.

Original sponsor followed by new sponsor/umbrellor girl/budget advisor.

I got the stock april guard for 120 including freight.

Looks like theres only 2 ways to get money for me now. Ones as a electrician and the other is from my only sponsor using cunning technique(erectrician).

Almost done. Waiting on guard which should arrive tomorrow and Front axel sliders from the UK whick should come next week. It really nice in the handle bar seat and peg position now compaired to the xbars and lower seat. I can get down low and weight forward.

After next round carby and airbox.

New muffler seems quieter and I can push start it from cold now. It maybe the new rear shock is giving me more traction when starting. Im not sure if the muffler mods could help with starting or not but it seems to run better.

I put a set of new bt39s on it. They have only done the last meeting. Ill run those until summer or maybe longer as they seem to grip ok at 20pounds and heat up fast even when it was cold.
I would doubt if i have alot of power with this motor so ill maybe 2t it at some point or fxr150. Its a bit slow up the hill and across the top straight. maybe a good carb will help as I think its got a 24mm xl125 carb(guess only).

I got a letter from IRD yesterday for my 40th birthday and it seems that they want to give me 950bucks so i think I will need a 28mm flatslide and 1/4 turn throttle. Not to sure about tuning carbs if anyone in Welly wants to earn some beers to help set it up would be good.

Depends on what carb you are talking about. I would go to a 30. Unless you are talking a 28 FCR.

Nope. Its xl185 sleave xr200 head tl125 bottom end with xl 125 crank 156cc with this bore. Theres a xr framed bike running the same set up with cdi unit fitted but mines still on points. If it helps its noticably one of the slowest bikes in a straight line also if not the slowest. Idd be surprised if I had 10hp also.
I really do need another motor but not for a while yet.

Ahhh ok, thought it was 167cc? Technically I think it's still over, per the rules but close enough!!

I guess it classed rebore under 158 but if there is issues I have a .25mm oversize xl185 piston that I can bore the sleave even bigger to 157cc and say its a 125 bored to 157 with a piston(open). Im not expecting any inquiry and everyone seems happy at the track with it. The you tube link earlier in the thread shows up the hill and accross the top of Kaitoke its maybe the slowest B grade bike in a line on the track last meeting.
Its most likely ill fxr the chasis when im good at riding it and need more power but im having a heap of fun trying to make passes stick with corner speed and gapping the passed bike down the hill. Im wondering if thats going to be the most fun part of riding Kaitoke so im in no hurry to build a ultra fast bike.

[Henk]

Mossy

Out of interest stick one of the fast guys on it and see what they do. I ran Michelle's 100 in B grade down there last time we went, 8.2 horsepower, crap starts and mid pack finishes, but also the most fun I think I've ever had on a bucket.

I think the result would be the same. Im handy in the corners and running mid b grade( first meeting) but I lose 7-8 meters up the hill against most bikes and 4-5meters across the top straight but regain most under brakes. Im also 20kg heavier than most of the riders lol.
Im having fun with both the building and the racing so thats the main thing. Maybe later ill go for horses. My biggest achievement so far is I can push start it by myself now and its fun to ride it. Its also great to get away from the house and out doing it.

Problems HELP YOU ENGINE PEOPLE

Had a back fire and poor running maybe from new exaust. Happens while under load only.

Took the carby off and looks like manifold leak was one issue but

Head has been ported out to 31mm
Intake manifold to 28mm
Existing carby only 24mm (for sale if you 2 smokers need one at 24mm DREW?)

I take it best bet is for me to run 30mm flatslide and take the intake out to 30mm??????????

A previous owner must have kept his carb and chucked the tl125 carb on it to sell bike.

Rule number one bigger does not necessarily mean faster. Strange but true
Rule number two when porting cylinders it is common to add material to the ports in some places and remove from others.
I would fill the port floor to straighten out the port and run a 28mm carb seeing you have a reasonably std motor. couple this with a nice short intake of a Suzuki or something like that.

A few hours on a flow bench and some plasticine maybe in order?
If you pm me your address and i will send you a free intake manifold

[mossy1200]

Thanks Hus.

Putting the 30mm on with a shortened intake manifold that my mates going to make and blend. 28mm might have been better but I can re-use the 30 if I get a fxr engine later.

Front guard fits well and clears the disc well.

Four stroke runs rough, but only under load...Weak spark would be my first place to look.

Thanks for the carb offer, but I've got factory support on parts already:cool:

Just started after new muffler Drew. The old system had 2 mufflers(well one was a sort of skwished pipe inside another pipe). It seems to be lean. Ill fit up the new carb and try again.

Just started after new muffler Drew. The old system had 2 mufflers(well one was a sort of skwished pipe inside another pipe). It seems to be lean. Ill fit up the new carb and try again.

Cheers mate, talking to Bryce earlier and he thinks I might get away with running a single carb, which I already had on the DT, but if not I'll try and source two 17mm flat slides which fall just on the 24mm limit by working out the surface area.

Yeah . I did those calcs also as i was looking at a complete bike. Y intersection and 24mm would be best as it 180deg crank so so suck big twice as often would be better.

Yes I cut the old first muffler and he had reduced down to about 10mm by 30mm with and tube inside the cone shaped like a expansion chamber. Also the welds were all poo inside with bit of mig still inside like a 10year olds snotty nose. I should go take photos because however bad you think it was your only half way there.
New muffler is straight through. Im looking for a better muffler with larger volume as I think the one I got is at the noise limits. Even if its ok idd rather be on the low side.
I may even miss the next meeting if I have tuning issues.
Do you think its worth a dyno tune Drew? ill def get a better muffler first if I chose to dyno tune the carby. Most likely this one.

Depends what you're gonna do to the motor mate. Flowing the head, lightening the crank/rod, and enlarging the valves, might get you close to the poke of an FXR with a carb and pipe, after you spend some time on the dyno.

The build is the most fun part for me at the moment, (but it would have to be since I haven't even raced mine), so the dyno time will help teach you engine building pros and cons I guess.

Head ,cam and valves done. Crank has stroke of xl125 so assume it is. someone has spent money but I think they removed a good carb seeing as manifold was 28mm but carb was 24mm.

Im just at a stage where any parts I buy need to be good enough to fit onto a FXR motor incase I get one later and hot it up before installing, hense the 30mm carb instead of 28mm.
I really dont expect this 2 valve motor will ever deliver much more than 15 unless its very well set up and then even 20 would be a mission to find.

You know it's a serious motor, when to keep the gearbox remotely reliable, the oil is so thick it needs to be pre heated by laying a fan heater under the bike.

If they are Cv it is the best way. (not as good as FI though obviously)
You need a pitot tube and a a rising rate fuel reg.
Suck throw is easy but fueling is hit and miss. plus if you try to do suck through with carbs plus inter cooler you effectively have created a bomb.

Found a suitable cast pistons but lifespan would be short.
the other bit is the destroking with metal spraying the crank or custom job$$$$$$$$$

The rest of the parts are easy intercooler easy familar starlet etc

Two strokes are lighter and would be cheaper and more reliable unless you are gifted and or have a huge budget....... would be fun though.

Doesn't matter what carbs you run. If you put them in a pressurised box and feed it air, the balance is always perfect ans there's no danger of pumping fuel out of the over flows.

Not optimal but probably get away with juggling rod length / stroke to get compression down, keep to forged flat tops. Custom crank isn't that hard, but I've got the same problem; I can only afford to do shit like that if I spend most of my time working...

"Non-competition" is the determining test for legality.

I know I should let this die down and let Mossy have his thread back bu I can't help myself...

Flat-tops would decrease comp hugely by themselves, the 250/4's I've seen inside all have contoured tops to get the 12.5:1 or so ratios that they run.

Main problem of all this is that the motor is just so damn tiny.

I elected to get a much more cost efficient 2-stroke. That's a comparably easy build but it still stretches my resources super thin.

Even with allowing for the reduction in comp with the destroking to achieve the needed 6.5:1 for the 22 psi to make the supercharging worthwhile it does need dished pistons or no squish and massive detonation.

Anyone attempting to do this should exclude the Honda CBR250 from there list of options as well as there would be bloody hard to destroke. The Kawa is to too overquare imo as well. That only leaves the suzuki or the Yam and the Suzuki's looks a lot less advanced in regards to its head design.

Sorry Mossy, gotta have another word.

6.5:1 for the 22 psi

Without pulling ten books and a calculator out I'd suggest that the comp ratio could be way higher for such a small combustion chamber.
12.5:1 for a std GSXR250 if I recall correctly; that will run quite fine on 91 octane.

All the calculations i was able to muster (Plenty) pointed to those to get the Hp i was aiming for.
The heat was the issue (these were i should say based on a Routes blower) which by nature of their design transfer a lot of heat if you can use a say screw or centrifugal blower yeah you can go higher for sure....
but the manner in which the there boast is delivered is much more problematic...... same as a Turbo scenario for instance
If anyone is dead serious i will see if i can retrieve them? maybe start a separate thread to stop clogging Mosseys.

In the words of Eddie Vedder; Its evolution Baby!

But is it better for my purposes?

[F5 Dave]

Well I'd start off by guessing the older piston port version is cast iron barrels from memory & the 1/2 reed version is ally with sleeves? That in itself is good, or at least better than all iron. My RG50 is still 1/2 piston port so they can be made to go ok, but it is old fashioned & there are better arrangements, but only with an outstanding amount of work to get it right. Might even find the latter barrels have extra transfers. Suzi used a single pair for many years in its older kit.

If you had the money I'd work out how fast you can make the fcker spin & rebuild the crank with decent parts & fit some nice pistons, maybe KX or KTM65 might be within size (pistons are open). That would mean you could spin it up to 13,000 & make use to the fact it is a twin.

Using old parts I think 10,000 is probably safer. The issue is old parts tend to die when revved. I went through a lot of old engines when I first started as they seemed cheaper to buy than a rod kit. In the grand scheme I was very wrong.

We use forged KDX50 pistons in our RG50's, Wiseco p/n 826MO4100 they come in std 41mm through to 43mm which is the std size for a GT125. Kawasaki KX60 pistons start at 43mm Wiseco p/n 648MO4300 both have 12mm L/E pins.

RG50 bore 41mm stroke 37.8mm GT125 bore 43mm stroke 43mm

We have some GT125 engines here and were thinking of using Aprilia50 rod kits, de stroking the crank to 36mm and using KX60 pistons to get a 100cc air cooled twin. Or use two RG50 cylinders and de stroke the GT crank to 37.8 for a 100cc water cooled twin.

Some GT125 engines have piston port and some piston/case reed port but they all have air cooled alloy barrels. The hard part about converting them to 100cc water cooled is that the cylinders are very close together and fitting two RG50 cylinders may be a bit of a challenge.

So using the original cylinders and de stroking the GT may be the only practical solution but then you get an over square bore stroke ratio and the motors themselves are fairly heavy.

The best we have got out of any of the RG50's is 14 rwhp at 14,000 rpm so that is roughly 28 for a 100 twin and we are already pulling 30+ from the GP125 rotary valve single and its a lighter motor.

But we do like the sound a twin makes ........

We use forged KDX50 pistons in our RG50's, Wiseco p/n 826MO4100 they come in std 41mm through to 43mm which is the std size for a GT125. Kawasaki KX60 pistons start at 43mm Wiseco p/n 648MO4300 both have 12mm L/E pins.

Wasn't the X5 and X7 six speed boxed? Could be a solution to the gearbox there.

RG250, stroked down with two RG 50 barrels. Hold on...I've got an RGV motor. Short stroke that, chuck a sleeve down the barrel and Bob's my uncle.

There are too many possibilities.

Got the bucket going again. Not on new muffler as its not arrived yet.

Took it for a we ride. Goes good at bottom and top end with hole in middle.
Any tuning tips. I have a full set of main jets and fitted a 120 to start off with. Needle is in the centre position.

Its to loud. Even worse now I have a bigger carb. I dont want to do to many carb changes until the new muffler arrives and is fitted.
Im curious about the carb needing half throttle to get through the mid range. Is it possible it may need the needle lifted a slot or 2. Top end seems to say the main jet is ok.

Yeah mines only 2 valve so 120 might be enough. Its feeling lean in the middle. Thats needle height issues?

Im tempted to get it dyno tuned but no time before the weekend and would need muffler done before that. Im hoping the new muffler will almost go straight on.

I don't think that qualifies as 'welded' bro.

[mossy1200]

Is nasty. I should have been worried when the tardme seller advertised muffler weighs 700grams. I think my braze solder weld weighs the same. I tried sanding the chrome off first and I think I reached the chrome on the inside.

Like painting a air guitar with invisable paint and Drew not liking the colour.

[Drew]

I couldn't do any better mind. You might get to point and laugh at my welds on Sunday if I get the bike finished tomorrow. The only thing I can braise is brand new soft drawn copper with a mapgas and new silfos.

Just put a coue baffles in the one you have. A reducer front and rear is the best way, as you don't need to go so small that it is restrictive like a baffle at just one end.

All set. Went for a ride. The gasket intake cement didnt work and goes well but runs on with a air leak when throttle off.
I have turned in a lip for oring to try again

Where's the pictures of the intake manifold bro?

Busy day Drew. No time for pics. Called into work and 4 hrs of wiring friends place.
Had a mini disaster today.

Touched the rear valve and the suka broke off at the rim. Lucky just in time for Tonys Tire and got another.
Spent a hour driving around to find a O,ring today. Repco -no, SCA -fail, Bunnings tried selling me a tap washer -wrong.
Motorad YES.

All done in the carbs but ill need take the jet kit for track tuning as Im out of time.

Also fitted hinged pegs but now my stand wont work as the old bike stand used the pegs.

Made another stand. Temp so no laughing at the track. A chair died in the making. Rest in piece crappy brown chair I never liked.

EDIT- I took photos last night because I knew Drew would ask.

Have seen a pretty cool rear wheel stand made from a super market trolley .... :whistle:

Im happy thats not bad for a xlish engine.

It had under 12 when I took it in there so almost 20% gain from timing and jets. It most likely had under 10 with the 24mm carb on it. Looking forward to the handling and running when its a fine day on the track now. Im hoping I wont lose as much ground up the hill and on the top straight now. The rest of the track is cornering anyway. The fact the bikes 103kg with fuel and im 100kg with leathers on doesnt help LOL

[mossy1200]

Didnt do a run without the probe in so I could be even closer.

I'm at 200% budget now.

Levers wernt straight swap so 2 hrs of filing later and they are on. The olds will still fit as spares. fitted some better sliders also. found a guy that has alot of slider plastic so all sorted for future also.

Im thinking of a second bucket now and put some wets on it or the x1 tires with extra groves cut and put slicks on this one.

And here I was thinking nobody would see. maybe that bigger valve motor might be better and a swap over may happen.
The tire groover could be handy. Are they expensive to buy? The tires I had were ok in the wet but not great once leaned over due to lack of tread near the sides. just need grooves taken further out and maybe twice as many for a wet tire.

What you do is this. Get another project on the go, when she gives you that "sit sown and prepare to wear the last ten years of frustrations" look on her face, explain that you thought the old bike would be perfect for her to have some fun on. So you bought another one for yourself.

Down that road lies chaos, and a shed full of buckets.
Mind you if you can get her hooked it's all good, the race budget expands considerably and trips down the line with a van load of bikes get really easy to justify.

Mossy, got some mates heading your way in a month or so if Drew can't find his groover in amongst the leaves in his shed.

I came after the Rain slowed,(To a sporadic downpour) even us coasters are not that silly.

I had a look for you and Mike must have walked past where you were twice at least don't take it personally i couldn't find Greg either.
I did see a MB100 (Kevin)execute a nice pass on the leading Hoogie only for it expire,Shame he was wringling the little Honda's neck nicely and it was going much better than last years
I understand someone else may have had a similar result after passing one of the Hoogies as well but missed it.(maybe passing a Hoogie is bad luck or suicidal)
To tell you the truth i was rather surprised at the general lack of carnage.
My son enjoyed it but the bucket field was as thin as i have ever seen i will be there racing next year or divorced.(or both pos)
That way i can show you how a real pro.....crashes.
I missed the Darren Hehann tractor show as well. i guess he must have munted it early this year.

i understood it was the next corner after the hairpin. I was lead to believe he immediately crashed ie the next corner after passing the leading hoogie on the hairpin
I understand also from Phil garret commentary. that anyone can pick up these buckets for $500 each. So therefor can i have yours and Budha then.....

PS right hander funny..... theirs only one left at GM. That's why i always try and watch there.plus you can see three corners.
