Hey guys I have an 02 banshee .010 over pump gas with trinity stage iii porting. The quad has been sittin in my garage for months at a time, I start it once and a while.(always with fresh 93 and amsoil 40:1) When I start it with the choke, it runs perfect. As soon as I turn the choke off it on cylinder starts to drop out. If I can remember correctly its the right cylinder that cuts out.
My question to you guys, is this a lean condition since the choke kinda fixes the problem? Also what else could cause the cylinder to cut out on a fresh motor?
Also what would a base line jetting be? CPI inframe, stock carbs, vforce reeds, k&n air filter, stock air box with vents, and pump gas trinity .010 bore. I think they killed the head a little too. I live in Long Island, New York in case you were wondering altitude.
