Hyosung needs new chain at 4,000km

[CookMySock]

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.

That is sensible advice, but not in the case of the Hyosung chain. 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.

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).

As above. Its cheap junk.

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.

Fully agree. This is the next mod for our hyos, after chain, tyres, lights, suspension.

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.

Steve

ha ha i will do

[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.

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

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.

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

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.

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?

I'm sorry, I do not know. There is a GT250R service manual somewhere, and that will tell you, or else some knowledgeable shop-person might be able to give you a straight answer. I'll measure up our chains and see if they are the same.

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

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