Hilarious Posted June 28, 2010 Report Share Posted June 28, 2010 i have a 421 drag motor. i have alot of bottom but no top. i have a set of spacer they r between the cub and reeds. My question is should i run them or not? only if they are needed to space the carburetor on the left side of the engine to clear the clutch actuator. what kind of 421, cub or twister?

RadarRacing Posted June 28, 2010 Report Share Posted June 28, 2010 The spacers hurt topend very slightly but you should have topend. Do you happen to have a ricky stator? I had a bike that ran great till the top of 3rd then I'd lose to buds bikes. Mine was a bad ricky stator. Otherwise check pickup gap, plug caps and all electrical, reeds..., Quote Link to comment Share on other sites More sharing options...
