Rotor for Rephased Crank Yamaha XS650
Rotor only for rephased 277-degree crankshaft to use with the Compass Ignition for the Yamaha XS650.
If you already have a Compass Ignition for the Yamaha XS650 with a standard crankshaft and have modified your crankshaft or wish to modify your crankshaft at a later date you will require this modified rotor.
We supply a rotor modified for the rephased crank. This is an additional rotor to the one supplied with the Compass ignition with a standard crank.
