I put an SE Compensator Kit in my bike a couple of years ago. Went for a ride a couple of weeks ago and noticed a slight vibration in the bike, ( This was after I changed the clutch hub bearing). Anyway I thought nothing of it at first, then when I gave it some in the higher revs the vibrations were really bad. Well I dropped the primary tonight, to have a look at what might be the problem. I was hoping something easy. But alas it never is. Anyway on first inspection everything looked ok. When I noticed magnetic crap inside the case, the first thing that came to my mind was the rotor has crapped itself inside the alternator. And yep it has... As you can see from the photo. There is minimal damage to the inner primary and case. A few scratches at most where some of the magnetic material has come between the rotor outer face and the case.
Anyone have any thoughts as to the cause?
Hopefully I will be able to just buy the Rotor on its own as the rest of the kit is good. The Stator is fine no damage of any significance, which is a relief. I cleaned it up and got the major bits of the magnets off as the rotor is non ferous....
had a magnet come loose on my old bike and screw up stator as well aj,looks like a magnet has come loose,replace both parts you can get a rotor with enclosed magnets and end that problem,cheers
