Does anyone find a cam chain tensioner blowing at only 4k miles a bit odd? The bike did sit for about 8 years with low miles (977) after original owner didnt want it. I have a rattle in the front end by windscreen at about 3-5rpms and read it could be the cct. When im riding it sounds like its coming from up front but when idling the right side does seem a bit chattery. Could it be anything else?
