Recently bought a 2000 model 929rr. I have ordered a new chain and sprockets for it, as the ones on it are slightly worn. However, the chain needed adjusting, the manual calls for 1 and 3/4" of play, this seems loose, I understand that suspension travel will obviously effect the slack in the chain. I"ve adjusted the chain a couple of times, one time using roughly an inch of slack with the bike on its kick stand (don't have a spool stand atm, tho that will change shortly.)
My question is this, after adjusting the chain, it became far to tight, so I loosened it, back to the orginal 1" of play, then the chain became far too loose, with roughly the original 1 and 3/4's of play. What is, in anyone's opinion, a good slack adjustment for this chain. The current 1 and 3/4's is VERY NOISY. not just chain slap, it sounds as if the transmission is falling apart..however, after extensive checking, it is just the chain making noise. With the chain tightened up to 1" the noise goes away, and the bike performs fine, but it seems hard to figure out why the slack comes and goes like it does. I'm assuming its because of suspension travel in part, but, in the end, if I tightened the chain on the bike while its cold and at rest, theoretically, it should return to the same slack position, say, the following morning after riding it the previous day. My chain doesn't seem to be doing that...any advice would be most apreciated..Thanks in advance.

you have the check your chain slop with sitting on the bike,get somebody to help you

lube will make alot of the noise go away. ya tried that? otherwise anywhere between 1 and 1.3 of freeplay is what you want.

Wow! thanks for the quick response guys, really appreciate it. tightened chain with my wife sitting on the bike, she's a bit smaller than I am, but close enough, Chain noise quieted noticeably. And yes..I use Blue lube on the chain, clean it with seafoam, (yes, its a fuel additive, but it also is a solvent, that is relatively safe for the o-rings.) New chain and sprockets are on the way, and will be installing them as soon as they arrive. Again, appreciate the quick response.

found another problem with the chain, and why it was a little noisy, seems I'd lost part of a tooth on the front sprocket, new chain and sprockets arrived today! any suggestions on the change out to make it go smooth? I also noticed there is no master link, I'm assuming I'll need to get a "press" tool to remove a pin,and the replace it, and will need some form of "riveter" to mushroom the pin once its in place? Thanks in advance for any advice, info, etc.
