Hyosung needs new chain at 4,000km

[2fellas]

well looks like my chain is stuffed :mad: goew tight then loose so better bite the bullet and get a new one any advic:angry2:e ?

[2fellas]

ha ha i mean goes tight then loose ......bad spelling

[HTFU]

There must be a wide range in the quality of chain as well as differences in the way the bike wears the chain out.

My GPX has done 18000km on the original and its still in good nick. My GN went through them every 6000-8000ks. I clean and lube the same for each bike.

GN chain was not very expensive so maybe look at a similar O ring chain to what the Kawasaki Ninja has on it. May cost twice as much (not sure have not had to replace yet) but way less chain adjustment on my GPX.

[2fellas]

yea i seem to be adjusting it a fair bit ...it has worn really weird good in some parts stretched in others ,i clean and lube every few weeks as well , maybe its just a cheaper grade chain
wonder if its a warrenty claim :laugh:

[RantyDave]

You might have over tightened it at some point. I've seen both chains and sprockets stuffed *really* fast by riding with it too tight. It does need some slack and (this is the hard part) you need to measure it with your weight on the seat. For extra marks you could ensure it still has a little slack in it once the suspension is fully compressed.

thanks mate :shit: my mate is bike mechanic and has just moved back down here from whangarai ( opps spelling :confused:) and wil sort me a new chain at cost ...phew ..will leave it to him to adjust from now on :laugh:

[DarkLord]

I got my chain and sprockets done at about 28,000 k's or so for $249 from Cycletreads up here on the shore. I had an X-ring chain fitted so hopefully it should last a bit longer. Apparently the Hyosungs do go through the chains pretty rapidly though so don't be too surprised if you find yourself replacing it somewhat regularly.

advice = sell the bike get a new one

[2fellas]

thanks mate yea i heard that VTwins were hard on chains ...

[CookMySock]

Nah the hyo factory chain is a cheap one. Slap a new one on - end of problem.

Try them on for a warranty claim though.

[Scouse]

thanks mate yea i heard that VTwins were hard on chains ...Ya choc nob its all to do with the cheap as chain that Hyosung fits to thier bikes, not because yer 250 v-Twin is pulseing the life out of yer chain.

[nivram]

I'm still on the original Hyo chain 10,000ks later with very little stretch in it, I just lube it and clean it every couple of weeks. I guess I've just been lucky so far.

I used to have A Suzuki DR that would eat chains every 5000-6000ks and develop tight spots.

[puddytat]

Ive heard it be said that a non centered sprocket can stretch yer chain odd like too...
Wee strips of beer can round ye studs like fix it noicely,makes up for the shite manufactoring tolerances eh......:drinkup:

[DarkLord]

Just a suggestion -

It may not be necessary after only 4,000 k's but at some stage it may be an idea to look at getting your sprockets replaced as well, from what I hear putting a new chain onto worn sprockets will wear the new chain out faster.

Like I say it's probably not necessary after only 4,000 k's but something to keep in mind anyway.

The distance travelled doesn't matter. If the chain is worn then so are the sprockets. it false economy to replace one without the other.

I am suprised at the chain wearing out at only 4000 km though. It suggests that you do a lot of riding in adverse conditions (ie wet and/or dusty roads). it would pay to fit a scottoiler or similar oiling system at the same time as your new chain. The saving in chain relacements will pay for a scottoiler in only 4000km.

The hyo chain, along with its rear shock, is the cheapest junk you have ever come across, and it spoils the overall feel of the bike.

ha ha i will do :beer:

[woza]

i am adjusting my chain quite regularly now (have done 8500km)... what wears out the chain quickly. I commute every day to work as well as weekend rides when the sun is out. Is commuting ie. stop start traffic bad for the chain, as well as riding in the wet?

Sorry to hi-hjck the thread.

[DarkLord]

DB, agreed the rear shock on the Hyo is a piece of junk.

How much would a decent one go for?

[2fellas]

yea i use my bike every day as well .....work and back weekend rides

good question all i did on mine is crank up th e preload one notch made a big difference

[CookMySock]

i am adjusting my chain quite regularly now (have done 8500km)... Watch out!! If you adjusting it more and more, the damn thing will break on you and do mucho damage! There is a procedure to check chain wear - something like taking a measurement between ten links or something. I strongly recommend you get that chain checked before it smashes a hole in the back or your gearbox or bends your output shaft.

edit: From the GT650 manual :
Count out 21 pins (20 pitches) on the chain and measure the distance between the two points. If the distance exceeds 319.4mm, the chain must be replaced.


DB, agreed the rear shock on the Hyo is a piece of junk. How much would a decent one go for?Well how long is a piece of string really. If you pull the shock out and take its measurements, you will see many suzuki/kawasaki shocks almost fit in there - $100 to $400. Or you could fork out for something a little more exotic.

I have got almost 10k on the original Hyo chain and it is nearing replacement - will go with a good replacement chain and sprocket set - will also drop a tooth on the drive cog. The chain/sprocket is also showing the usual tight/loose thing. I think this is due to uneven wear on the sprocket. Cheers DJ

[2fellas]

yea i was going to go to a 15 tooth front sprocket to make 1st last a bit longer and not rev so high on state high ways :)

[Nagash]

I'm having to replace my chain and sprocket at the moment after 10'000 miles.

Take heed of the advice that your sprocket may not be centered.

That really quickly buggers up the chain and the sprocket, easy way to check is just get a long pole and place it against your rear tyre, it should run parralel with the front tyre (Obviously not touching, rear being wider than the front)

---

But I agree with above, if you have to replace the chain, replace the sprocket at the same time. Otherwise the sprocket will bugger up fairly soon, and will ruin your new chain at the same time meaning you'll then have to replace both in the even nearer future anyway.

[woza]

So when exactly do you know when you need to replace your chain? I would assume (sorry relatively new to biking) that you would replace chain when it gets close to the end of adjustment?

Thanks for the help.

does this apply go 250cc bike?

Thanks mate.

Yes. Your doing a lot of acceleration (higher stress) on the chain on take off, your probably also doing a bit of engine breaking which is also more stress on the chain. If you ride all seasons as a commuter then you will get more junk in the chain especially when the road is damp (not fully wet) your getting burnt rubber and goodness knows what else building up on the chain.

All of this leads to K versus K more expensive maintenance wise than open road riding.

They say technically you should oil the chain after every ride especially in the wet but who does that :whistle:

Once every week/2 weeks will keep it running well especially if your using proper chain lube although the crap goes everywhere.

[Rev DJ]

The measurement for the GT250R is the same: Drive Chain 20pitch length 319.4mm. Cheers DJ

[CookMySock]

Thanks Rev DJ.

People, go back a page in this thread for a full explanation and a picture of this chain measuring procedure.

Steve

[woza]

thanks for the advice... turns out my chain was close to 322mm, needless to say it has now been repalced!!

Thanks again.

How much to replace? Did ya get your sprockets done too?
Cheers

[woza]

yeah chain and sprockets were round $350.

[Rev DJ]

The chain and sprockets on my red machine are needing replacement (10,000km). I have done a bit of searching on this site but dont seem to be able to find any specific make/brand recommendations? I am hoping to upgrade from the stock Hyo chain and sprockets - which brand should I look at? Cheers DJ

I just got mine done at the bike shop... I asked if they were better quality and he said they were. Not sure on brand tho!!
