    I'm using a 30t motor sprocket on my 47 WL. If I change to a 33t, does anybody know how many rpm I can expect to drop assuming a good clutch and using a 16" rear wheel? Chris

      30T 60MPH=3680RPM.......82MPH@5000RPM

      33T 60MPH=3340RPM........90MPH@5000RPM

      34T 60MPH=3250RPM........92MPH@5000RPM

      This is with 5.00 X 16 or 4.00 X 18 tyre. Both around 26" Diameter.
      If you use metric tyre speed will be less due to lower profile.

        Thanks a lot Dave. Kinda felt it was working hard at 60 with the 30t. It sure is a lot smother now with the 33t and little harmonic vibration in the bars. Chris
