[QUOTE="BrettC95, post: 218373, member: 4767"] I believe I've found the culprit. Valve clearance is within spec on intake. Exhaust, not so much. .23mm and .18mm. along with clearance being out of spec, the bike jumped time. Cause most likely being a loose chain which brings me to the cam chain tensioner. Went back to look at it, and it's somehow cracked?? Not sure how or why but it needs to be replaced. Thinking of just having the whole top end done as well as throwing in some hotcams. [/QUOTE]
