636 Engine Problem - Need Help

Check it out so I'm doing a chain saw and after I let go and pick up the bike I notice this clanging sound in my engine which gets louder the higher RPM's I'm at so I pull over and listen. It sounds like a bolt is banging around inside of the engine and when I speed up it stops but when I'm at the same speed it gets real loud like when I'm at idle and ****. If I turn off the bike and let her coast there is no noise. I think it might be the cam chain tensioner, what you guys think?

I'm gonna try fixing the CCT today by putting the bike in 6th gear, turning it off and backing it up 20 feet. I heard thats how you tighten it up the getto way LOL.

Sounds like it could be the CCT they make more noise at low RPM when you give her the cain is spinning so fast it takes up the excess slack in the chain....Take the cap off the CCT rewind it and let it back out, if that doesnt help get manual CCT

Re: 636 Engine Problem - Need Help

how loud is the clanging noise?? if its REAL loud, it could be a loose cage, or if you run a bar through header cage (905) the cross bar could be touching your oil pan..which creates an awful noise....if its not quite as loud it could be a cct..but alwys start with the easiest possible fix first..i.e. cage.

Re: 636 Engine Problem - Need Help

i dont think a lot of people realize your motor doesnt get much oil when its on its side..ive heard a lot of people blowing their motor doing hyperspins and chain saws..when i do chain saws i throw it down quick and pick it up high...also the stuntex has seemed to help me
