Will running oval make a difference in the gearing for the 13mm or is it not a good choice for that application?
I primarily run oval. There has not been any time where the 13.0mm rotor has been faster, other than in a 4.5 or faster motor. That is the only time. Stick with the standard sintered rotor in oval.
