Well, after doing the schwinn Chopper for the kids, thought it looked like fun so I thought I'd try something full size. Finished it this morning (although I'm going to get a different fuel tank which will mount in the same spot). I wanted something that looked like an off-road bike, so it's got a high pipe. The engine is a grubee 50cc (lots less horsepower than the 70cc it seems, might be the fact that's it's geared a lot higher) Anyway, I've already lifted the jet needle one click to the third slot and it still seems lean. There's one click left but I'm going to watch the plug and hopefully it's OK now. This bike vibrates a LOT less than the OCC bike. I was going to call it the Stealth Bomber, but the kid thinks it should be called the Red Tailed Hawk. These bikes sure are fun to mess with.
