down fall of sharing the drivetrain with the wing(lots more wind drag and common to pull trailers)Thanks for the add. I picked up a 1998 F6C Valkyrie. I really love it, but it seems to turn high RPMs on the hwy at 70-75. Does anyone know if parts are available to change the gear or final drive ratio. I'm wanting less RPM's at 70-75 on the hwy.
