I replaced my chain and sprockets 2 yrs ago as well as had a mechanic change a bearing in the engine that was causing wobble to the drive shaft. now the chain has another 4k miles and is stretched again...after taking out links the rear wheel has a tight spot. any ideas what may be causing this? i'm about to get a new chain and sprockets but would like them to last more than a couple years... :?
 
Was it a 'cheap" chain?
Did you keep it lubed?
Remember adjust when cold, lube when hot.
Some chains wil ldevelop a tight spot if not correctly lined up.
I just converted mine to a 530 from a 630 chain, and sprockets.

Check the sprockets for play and teeth aren't bent or
gouged on one side. Make sure they aren't loose where the ybolt to the wheel/rim.


I have a 530 chain for sale if you need one.
It's DID o-ring, 100 link, I can add links if needed.

yes, it wasn't an o-ring. that'll teach me. what is the advantage of the 630 set? I think i'll go with a new one and hope it has all settled down. Otherwise the bike is great, very clean and lots of fun.
 
The 630 chains are larger, I believe it's wider actually. The bigger 4 cylinders came with these. If you buy good sprockets, if in doubt go stock, you'll find that a good RK chain has a 20,000 mile warranty and can actually reach it. :) For some reason my RK stretched and stretched until I switched from 80w90 to Maxima Chain Wax. Now, this isn't normal, but if you run into the same problem it's worth looking into switching lubes. After 5000 km it finally stabalized.

Re: chain stretch 550 e

Cheap chains dont last long. I once bought a cheap J C Whitney chain for my 750 and it lasted two weeks before it snapped, pulling a pin through a side plate. I have had the best luck with RK "O" ring chain or Tsubaki "O" ring chain. Expect to pay $125-$175 for a decent chain. When replacing the chain, always replace BOTH sprockets. Assuming a good quality chain, the most common reason for premature wear and stretching is improper chain tension. The only reason one tightens a chain is that it would not be good if it was loose enough to be thrown off and an excessively loose chain wil be noisy and vibrate more than is necessary. A chain requires NO pretensioning to operate correctly. Too tight is a NO NO. Loose will not shorten chain life. You want about 1 1/2" of slack above and below a straight line between the sprockets when the bike is sitting upright, on its wheels (kickstand and centerstand up) with the rider on the seat. For my 750 and 1150, this means that when I have the bike on the centerstand, rear wheel off the ground and I set the chain tension, I must leave 2 1/2" of slack above and 2 1/2" of slack below a straight line between the sprockets. (yes, I can move the chain 5" total of up and down.) RK "O" ring chains are factory sealed with lube for the life of the chain. It is only required to lightly lube/oil the side plates to stop rust on them. There is nothing to be gained by slobbering the chain with wax, grease, oil or anything else. I have about 15000 miles on the RK "O" ring chain on my 1150 and it has not needed adjustment since installed.

The difference between #530 and #630 chain is the link length. The numbers designate 1/8" increments. #530 chain is 5/8" in length from pin center to pin center, and 3/8" wide between the side plates inside to inside. #630 chain is 3/4" in length pin to pin and 3/8" wide between the side plates inside to inside. The sprockets for both are the same thickness. It is the distance between the teeth on the sprocket that is different.

Earl: How does your bike respond when you snap the throttle shut? When I have my chain anywhere close to that loose I really feel the free play when riding in the city. On the highway it wouldn't bother me.

Any kind of chain snatch is so slight as to be unnoticable. I guess I would have to say, none, the thing is dead smooth. Alot of difference could be attributed to the difference in power and the smoothness of the power impulses between the 1150 4 cylinder and the 450 2 cylinder. Power delivery is very consistant on the 1150. It pulls smoothly regardless of rpm

Perhaps my worn suspension is causing all the chain snatch. I'm hoping to take care of the suspension in a few weeks.

Earl I have an RK W-ring 530 chain on the Tractor at present and I hate it, it is noisy sloppy in use and seems to be adding to vibration. I will never use an RK chain again.

That would certainly help. :-)

I'm using the RK SO "O" ring. I dont know what the difference is to a "W"
ring. It could be a mass and resonance factor that causes the 530 to have problems that I dont have with the 630. Just a guess though. That brings me to another question then. What is your preference in chain manufacturer?
I have also good good experiences with high end Tsubaki chains. The only thing about them I dont like is that only a Tsubaki link will fit them.
(you can use a DID link in an RK chain and it fits perfect, not so with Tsubaki)

Earl the difference is that a W-ring has three seaing surfaces on one side and two the other, as opposed to a "standard" O-ring which has one either side, I honestly dont know why this chain is bad but I dont like it and will not use RK again I was intending to go to a Tsubaki next, but of cause that will be a while as the RK is a long way from worn, although I have had to adjust it three times in 7500 miles.
Then again with the hours I have been working I have not even had time to really check it for tight spots etc, I have just lubed it with a spray chain lube and kept riding.
