Well, I'm already head deep in this project. I got it a couple days ago and since the stock battery was dead, I decided to go right at it with the brushless stuff. Should be faster then the stock 150w brushed motor. Using the stock gearing for now; It's probably overgeared though. It's a 250kv HXT outrunner made for 36v, running on 24v sla with a supersimple controller. Might do a 9s lipo in the far future.
I got the bike for $30 plus $8 gas. In the honda I got 32mpg, pretty good for the thing. It's got a 2.2 i4 iirc. Average is about 28-29.
The first major problem came up (besides the shotty pinion boring and filling up the damn rear tire) and it's the throttle. I have a servo tester here and it really sucks to use. I want to use the twist throttle that's already on the bike. It has 3 wires and I really want to replace the pot on the servo tester with the thumb throttle. Let me know how I can do it, please.
It looks sweet with the body on, I'll get some body on pics when I'm done.
