If I'm sitting on bike which is can chain on.....idk if its a cam chain prob but I notice when the bike idles there a nosise like a pebble is in the head ...then as soon as I rev it up at all it goes away...an u can only really hear it wen u put ur head next to motor

 

its your cam chain tensioner most likely

 

+1 on what he said. Go to the Sticky area of the F3 section. You'll find How To's on replacing the tensioner. Takes about an hour.

 

I ordered a tensioner I guess ill wait an see thx
