I have heard and talked to people that did this only to regret it very shortly after installing the belt drive. Apparantly there is a very SMALL margin of error for installing a belt drive system. The chain drive system has a larger margin of error as far as measurements go. Get a chain a little off center, and it won't effect your riding much...get a belt off centered and your in for BIG trouble and a whole lot of belts being chewed up. Both the people I knew that tried this went back to their chain drives because converting to the belt was too damn much trouble. I would stick with the chain, unless you have some VERY precision instruments to line up that final drive system with. "Eyeballing" it just won't due.
