I just rebuilt the top end of my 94 banshee with wiseco pistons, put some last rebel racing pipes with power core 2 silencers , and a white bros boost bottle. I changed the main jets to 250 from 190 and now the damn thing won't start unless it is primed with fuel in the carbs and when it does fire it won't idle and backfires like crazy any help will be greatly appreciatd
PS fuel mixture is 50:1 this is what the local dealer told me to mix
