Hello everyone. I just signed up and I’m totally new to not only this site, but to mini bikes all together. I just recently bought a motovox i plain on rebuilding with my 16yo son. The motovox MBx10 is in bad shape, sitting outside for 4 years. Sold the engine and bought a Predator 212. Working on registering it and getting plates. Going to try and extend the bike 4-6 inches. I currently waiting on parts. I bought a torque converter, a new high flow air filter intake. Starting with a .035 jet. Going to have my headers custom made. a 230 lift cam with 30 degree more duration then stock. 22Lbs valve springs, I have no idea what gear ratio I’ll have or should use. But after everything is done, last will be powder coating the whole thing 2 stage Candy apple red.
