    Default Flywheel magnet disappeared!

    Need your opinions here. I have a 1983 gs750es. I was doing maintenance work on my bike, when remove the stator cover I notice a few black grainy particles, ilooked at my stator and it's fine, touched the magnets on the flywheel and felt cracks and one is missing, and nothing fell off when I remove the cover.

    I check the net where to buy a new one or a used one but ever I looked none are available, and if there is one problem is I'm currently in the Philippines. Can this still be repaired(wishfull thinking) or can anyone point me where I can get a replacement.

    Bike still runs but I want to replace it.

    I would think that the vibrations from a rotational imbalance would be rather severe.
    Don't run the engine until the rotor (flywheel) is replaced.

    Your modelís rotor appears unusual....for some reason....maybe different mounting technique. Will be very hard to find.
    Out of curiosity, you said you removed stator cover for maintenance . Was bike still charging ok? odd vibration?

    That's the weird part before and after I did the maintenance there was almost no vibration my. Other bike has more vibration than my gs

    No odd vibration to be honest almost no vibration, my other bike vibrates more than my gs... Yeah bike still charges OK hooked up a volt meter to the battery while I uy was running reved it to 3k rpm voltage rises up reved it up to 5k rpm voltage went up to 14.2v... Its running like no magnets where missing very odd, but I'm. Afraid the vibration no matter how weak or strong it is will in time destroy my shaft or remove the other magnets... Really trying to find a way to repair it or find a replacement.

    While I haven't personally seen it on the bigger Suzukis, the 250 and 400 fours are prone to losing these magnets. If they can be found in the engine and are in one piece, they can be epoxied back in place....At your own risk.
    There's got to be some of those 750 rotors around surely. Enough of them have blown up that there have to be some somewhere.

    It appears this seller will ship internationally and you can calculate shipping cost too.

    That one is for an 8 valve engine. Is yours an 8 or 16V engine ? 83 is usually the 16V.

    From memory, the shaft diameter is different.
