Anyone have or heard of this issue? I've put about 2.5hrs on my 2011crf450. runs not bad while turning laps. Pops a bit on deceleration which doesn't concern me but on the stand when you blip the throttle, it hesitates like a non fuel injected bike would that needs jetting! Even stalls sometimes! Even when entering a corner and the revs come way down, then you get on the gas to exit and it hesitates! What gives? Razzy43.
