After 8 years of my banshee collecting dust, its time to get her running again. My sig says what's in it. I put a set of 33 pwk carbs on it, and never could get it to run right after that. I was running turbo blue 110 octane fuel. Now I want to trail ride it, run just premium fuel, switch back to stock carbs so I can run an airbox with no lid. I had trail porting done by grand river racing, which is no longer in business answer my questions. I believe the reason I went to bigger carbs was the fact I was running my stockers dry of fuel. What problems do you guys think I gonna run into? Should I put 19 or 20 cc domes in my cool head to help with the fuel change? Any other advice? Can stock carbs hold up, or should I look into some 28 mm carbs to make it run right with an airbox?
