should I be hearing my valves?

Post by allthumbs » Sat Aug 02, 2008 11:09 pm

that is when I'm riding should I be hearing the soft rhythmic clickety click of the valves as I let off the throttle? It does not sound irregular at all and I set the tappet clearance to the correct .xxx. its like the sound when you push air through your tongue and the roof of your mouth and let your tongue rattle against it. .....right

it just worried me that I can accelerate into 8k rpm and then round a turn and hear this sound. sometimes it seems louder than others

is this normal? silly question?

Have you looked at the wheel on the cam chain tensioner? Have you adjusted the cam chain tension? You may have a cam chain sprocket with loose rivets. .............lm

Thx for the reply,

I was going to check the cam chain tensioner this afternoon. If i can find a detailed desrp how , it's not too clear in clymers. I've read some threads on it but I'm pretty thick. not too sure how to know if it's right. I'll keep searching for the answer or just get in there. I have a spare wheel so if its shot I can put a clean one in.

Are the loose rivets more than an annoyance? that is, will it be ok until I invest in some top end work in 2'3k miles?

thx

The tensioner wheel in mounted to the tensioner in a way which makes it difficult or near impossible to replace. HONDA didn't supply loose wheels for that assy. To inspect the tensioner you need to remove the 4 bolts and pull it out. You want to see a nice round neoprene wheel rather than one which looks like a sprocket with chunks out of it. Don't worry if it's hard (old rumor) because when new they are hard. As for the rivets I'd not ride too long before I repaired the part. ...............lm

thx again, I meant to say I had a extra assembly

how do I know that i have proper tension since I can't feel the chain while the motor is closed?

open the top and feel it?? or back it off and screw it back applying light pressure?

Loosen the lock nut and bolt on the tensioner. Remove the rotor cover and with a wrench turn the crank clockwise while watching the tensioner shaft. If you see it going in and out watch for the place it is into the case the most and tighten the bolt then the nut. ..............lm

hardly a detectable movement in the shaft. can't see it move I can just barley feel it. if I remove the whole assembly I'll have to clean it up and replace the gasket no?
