Going to Baja in Feb and I'm more than concerned that I'm going to want a higher top end. Right now I'm running 14/50 and I feel like my top end is around 55mph with very high rpm. Does anyone have any experience in changing the gearing to get a higher top end? I would like to be able to cruise at 70+ for long periods of time. Can this be done with the 426 or no? Any information would be very appreciated.
