I recently installed a GYTR head and cams with a GYTR hi-comp piston. The bike has ran great for the first 5-6hrs. This weekend though the bike started giving a pretty good puff of smoke after idling for a bit then whacking the throttle... obviously something is wrong?? Why would the bike hardly burn any oil during break in, and several rides thereafter, then suddenly start? Just looking for some input before I tear the bike apart to investigate?
