That is one SEXY engine! not sure im diggin the rims though, maybe if you painted them black.
What kind of paint did you use for the engine? Its got a sweet texture to it.
where did you get those wheels and drum brake set-up? They are pretty cool.
haha thats pretty cool. I hate floats as well. Anyhow i just purchased 2 gas scooters for 100 bux and got em up and running in a matter of minutes!
