I've done a lot of riding in the last two days. I am amazed at the gas mileage, it's gonna take me longer than I thought to burn up three tanks. I've been asked by about a hundred people what I was ridin on and I think these things are gonna get a lot more popular. One thing that worries me a little bit is a funny squeal noise that I hear once I get goin pretty fast. It sounds like a belt squeal in a car, but there aren't any belts on this thing so I'm not sure what it is. Could it be a bearing or something? I gotta say, I LOVE MY MOTORED BIKE! Any help about the squeal would be appreciated. I don't even know where to start.
