also 97 220 with 2stage boyesen reeds. running 40/145. stock needle 2nd clip down from top.air screw 1 1/4 turns out.dropped down from 45/190 (no ...not my idea of jetting-the bone head who owned the bike before me put those in). pc pipe,air box lid mod, at sea level. southern NH. i went down two pilot sizes because i was already a little rich on that circuit. flawless everywhere, except for the 0 to 1/16 throttle above idle. it needs just that tiny area to clear out before it becomes electric motor like in uniformity. but hey...it is a two stroke after all!!
