i just got my g3 toppin out @ the 40+ range but when im running wide, i will 4 stroke every so often. im up jet to 62 on the infamous square bing, and i got an aftrmkt chamber n a 40 tooth rear. bored out the airbox cause it ran so good without any air restriction.... it seems to run better than it ever has but, it pop in and out of 4 strokery at top end. ill choke a it a lil to see if that helps but that hasnt seemed to do anything. help? anyone? i tried the 60 jet as well... it 4stroked hard. even with o air restriction... got the best speed on the 62.
