yousaidpoo, I would get a kit from Jake! go to
www.aircooledtechnology.com send him an email and let the fun begin! he even has a kick@$$ video to show you step by step how to set the mother up! and it shouldn't be much more than the engine GPR mentioned... and everything will be right!
if you want an engine that's ready to roll, mikez has one that's a screaming deal!
how much are you looking to spend?
