Does anyone's cam chain tensioners whine @ idle? I think maybe where my wierd whine is coming from. When I scope it I get the whine from the tensioner housing all the way thru the bottom end in line with the cam chain. The whine fades as I rev the bike?(or the load exhaust masks it). Should this worry me? Is it a common problem with these bikes? I have had some noisey bikes and I know what valve, cam, bad crank noise sounds like and this is different. No different with clutch in or out. I know its tough to give advice without hearing it for yourself but any input is appreicated. Its a fairly loud whine and its a 929rr.

I don't know much about 929's but on my F4i the CCT rattled, not whined. It only did it at the 5,000-7,000 RPM range but made no niose at an idle

Did you have to replace it?? Because mine does that and it's really annoying.. is it bad for the bike?

I had mine replaced and it was covered under warranty. I have heard that a bad cct is will not harm the engine but I would deffinatly replace it

CCT can harm the engine. If it would go completely bad it will allow the cam chain to get way to much slack. This could cause it to jump time and send the pistons straight into the valves.

that's cause the cctl making noise in the F4i is not BAD...it's just that there are increases in tolerances due to wear, etc.

to the OP...if you had just recently changed the cctl (not cct...cct is the tensioner)...and used a manual one...it sounds like it's too tight.

When my CCT went, it sounded like someone driving down the street dragging their solid metal muffler.

If it doesn't sound like that, I'm betting it's not a CCT... just my observation though.

obviously no one is listening about the cctl ordeal.
do a search instead of asking questions.
then you can decide for yourself.
