I went with the R/S for reliablity issues,seems to run like ****.I need to find a source for the cotton-type air cleaner,I'm constantly cleaning it out and it looks like it may need new soon.I think staton may carry them,gotta check.I like the whole idea of gearing for power,I suppose you would have to convert to chain drive and not applicable for the gebe.Also, have you ever changed the fuel filter on the R/S?
