Re: what did you do to your motor bike today?
Well, when we're dealing with diff. manufacturers motors, get parts from a retailer of that motor. If it's a Grubee, go with BikeBerry or GasBike, if it's a Raw, get it from Raw. Etc etc.
Though, it would be nice to have some custom stuff made - I myself would like a custom machined 48cc hemi with a shortened skirt on the intake side.
