Re: My 2 stroke is 4 stroking..
For the record:
After downjetting to 68, mine was still 4 stroking a bit much. I just tested my earlier plug gap theory. I'd tapped to about 024 before, so last night I pulled the plug. The condition and color was perfect. Put it back in after yapping to 032, and just now got back from a ride. No more four stroking at all (unless I back off the throttle, of course).
