I put a Sparx 3 phase charging system on my 850 some years ago to keep up with halogen headlamps. The rotor that came in the kit was undersized and didn't fit the crankshaft, so I used the old Lucas rotor. Now I'm wanting to increase the output a bit to better handle my Li battery and I wonder if changing rotors could have any effect. Has anyone noticed a difference between rotors?
