I noticed popping on my america last weekend in Sedona, never before had I heard it on this bike. I did have major popping issues on my Honda SuperHawk after I installed race exhaust w/o jetting the carbs.
Ifit true that it is just unburnt gases exploding in the headers, then that would point towards a rich mixture, correct?
