Hey, you're in Flint! Do I have a deal for you!
I live in Waterford and have a piston, head, wrist pin and bearing (maybe even the circlips) from a Sachs that I put a 70cc kit on. The bike had only a few hundred miles on it, and all the parts are perfectly useable. Here's my proposition:
I'm hooked on Halo Burgers. They're heavenly. It's a real problem, since you can only get them in Flint (and the greater Flint metropolitan area). So, if you bring me two QPs with the works, olives and peppers, and two orders of curley fries, you can have the parts.
I know, I know, too good a deal to believe, but as a Flint resident, I'm sure you know that if you have a Halo Burger addiction, there ain't a whole lot you won't do to get your hands around one. Or two.
