2-1 single 35mm pwk carb jetting question


Recommended Posts

I'm kind of new to the whole banshee tuning world so everything is comming on slow to me. My setup consists of race ported jugs, vito's superstock pistons, fmf fatties, answer silencers, Noss machine head w/20cc domes and a 2-1 single 35mm pwk carb running 93-94 octane 40-1 mixture. My elevation here in pennsylvania is around 1000ft above sea level. I know every bike has a different attitude and reacts to mods different but i was wondering if anyone could get me close to proper jetting. What needle should i use? Also what jets do ya think i should run to get it close to fine tuning? Any help would be appreciated.

I wish I could help ya. There's only a small percentage of guys that run the single setup, so hope they see this. Im sure there's a lot of info here on the subject, try a search. You should also reply back with what jets you currently have in the carb and some details on the air filter system you have.

ok a little update. I ran the setup listed below and it ran great but there are signs of detonation on the plugs. If i started running a 50/50 mix of 110 and 93 octane, what would i have to change in this configuration?
