I was hoping to fit a YEC rotor to my 07 R1 and was worried about the charging rate to the battery. To the best of my knowledge (secondhand info) the standard rotor generates 3 phase electricity and by using a YEC rotor the electrical system changes to 2 phase.
I know absolutly nothing about 2 and 3 phase electricity, so I was put off the idea of fitting one of those rotors. I like having working turn signals and lights etc, but I didn't want to buy a rotor and have to lose everything.
I talked to a guy who was running a race rotor on a race BMW, he said that his torque fell off a little. Did you by any chance dyno your bike before and after?
