Im going to be rebuilding my banshee engine soon and heres what i have: Stock engine with v'3s and tors eliminated.

 

I was thinking: .020 overbore, cool head with new domes, v'3s, bigger carbs and adj. timing plate. My questions are: What size carbs should i get, what cc domes should i get( i want the most compression without having to run race gas), and is there anything i'm forgetting that might give me more power without getting into bottom end? Do the boost bottles work? I want my banshee to hit over 100mph. besides the tire info and front sprocket, is this enough engine work?

 

Thanks a lot!

Well.. welcome to bhq!

 

I would recomend a port job and a set of pipes to compliment instead of carbs. They are one of the last things i would worry about. Look on noss machines website they have a chart to help you figure out what cc will work for your elevation. I would stay around 150psi to stay on pump gas. As for other mods' look into a timming plate to advance the timming around 4*. Let us know how things work out.. have fun
