ok i understand since the manual recommends that you replace the chain and sprocket together.

You need to measure the the chain 20-pitch length. It's on the same page of the manual. This is the measurement that will ultimately determine if your chain needs replacement.

Also, since the manual says to tighten chain to 20-30mm, and you tightened it to 20mm, and it loosened to 28mm, maybe it loosened because your are at the tightest accepted value?

Also, did you perform the chain tightening on a stand or while the bike was leaning on the kick stand? the manual recommends that latter.

 

No thanks, I like not having to rev to 7k just to get moving at a stoplight.



But I am looking at a 09 R1, which is supposed have corrected this issue.

I did it on the kick stand, as recommended.

After measuring the 20 pitch length, it's at 12.5, which is just within specs. Since it's within specs for slack and length, I will go ahead and order the chain and sprocket set, but I guess it's not an immediate need.


Anyone want to help me put on a chain and sprockets?

 

I'll help Tim, I've got a chain press...but I don't have a riveter. I need to get a new chain/sprocket for the CBR too...hmm

 

Maybe we can have a "maintenance meet"? Chains, oil changes, etc?

 

that sounds like a plan. who has a large garage?

 

LoL, I don't have a large garage, but I've got a huge (5 car) driveway. I can just park the cars in the street. I'll be ordering a new chain/sprocket for the CBR tonight or tomorrow.

 

Same here. Want to start a thread to gauge some interest?

 

Not a bad idea.

 

chain is prob just streching out esp if your riding hard(wheelies and alot of hard acceleration) just spend some money and get a good chain and keep it clean and oiled

stock chains dont last long under rough conditions
