My SM doesn't pop much at all. Its all in the idle mixture screws and pilot jets. It does pop a little every once in awhile but under normal easy conditions it doesn't.Freak...155 main 48 pilot ...AI removed....gutted stock pipes...dyno at 13ppm pretty much perfect air fuel mixture. took some playing to get it there.

I learned all I need to know about life by killing smart people and eating their brains.
