yeh im changing it on the cam, if your going to try it i'd say 1 tooth at a time, min not shure how many teeth i moved mine my cam sprocket differs from yours in the bottom end im using the internals of a Yamaha ybr euro 2 engine where as ajs uses the Yamaha ybr euro 1 the difference being the teeth on the cam & crank sprockets are smaller as the euro 2 uses a different timing chain than the ajs euro 1 o ring type
Are you altering the valve timing by repositioning the cam chain? How many teeth from standard in the ride 3?
