I never had a minibike or fourwheelers or snowmachines or anything, it's my first motorized thing besides cars or trucks. I have no idea what I'm doing when it comes to motor mechanics. I'm really familiar with bicycles though... A local shop was selling these for ~$400 for the past few years, but I got this one from a guy on craigslist for 200. He said he got it four months ago, then stopped riding it after he wrecked in june. this is how I got it this was earlier tonight, in the middle of a pretty good test... http://i.imgur.com/gryzwP9.jpg I did some quick searching, and just on this forum there are quite a few stories about the fenders on these Schwinns breaking loose and getting in the spokes/wrapping around the tire and causing wrecks. Funny, that's exactly what happened to the kid I got mine from. I drilled some holes and wrapped some bailing wire a bunch of times around the fender/braces/fork, so it should stay put. If there's anything you can tell me to keep the engine in shape, I'd really appreciate it. I know the first thing I'm supposed to do is replace the spark plug/cable... What's the maintenance routine look like? Can anyone Identify the engine and point me to a manual?
