i like gapping them real small (points) to accommodate for floating and advancing the timing a bit to compensate. however, they were probably at stock before i did this and it made no difference. i still kinda think it's a jet problem. phbg's are weird carbs. the 19.5 i have on my bike is perfect. 40i and 98m on my un-port matched treat kit, just bolted up, no case/intake/nothin. rips like crazy where ever you put the throttle, idles nice, good plug. no 4 stroke. goes like 45, solid with low gears, (snow flakes) can't get it right on this mk 65.
