Well Doc said take two bottles and call me in the morning. So I am out yo, I guess I would have to test drive this but Seriously Belt Drive..... the yamaha touring bike will never be the same, However the shaft has been the show stopper for Trike Conversions, But I would have to cut alot of weight to even attempt one of those. If they have Cat converters that would be the first thing to go, however if its computer monitored that may be more trouble then its worth.
