I just recently purchased a non running 02 banshee. PO could not get it start after tinkering with it for two years. Topend has been bored to I believe 64.5mm, and wiseco pistons installed. FMF gold series Fattys, Powercore 2 mufflers, Mikuni 2-1 carb intalled. Im at 4000 feet above sea level.
I pulled the carb and noticed it had a 640 main jet pilot is not marked. Does this seem legit? As far as main is concerned. I'm assuming he added stock carb jets together and used that number for main jet on 2-1. Just seems really big. I've googled around and most other 2-1 carbs are running like 300 mains ( around there)
