    Those are aftermarket. Not sure you can buy anything from Yamaha that goes inside the supercharger.

    Not to be a Thread-Jacker but when my SC was out, it was pointed-out to me that there was a (very) little bit of oil getting into the intake airstream. I believe this was from a leaking seal(?). Anyone have this and know where to get the seal?

    Thanks.

    Aftermarket. You can't get any internal supercharger components from Yamaha.

    Craig, more than likely this is just a normal amount of oil that enters the supercharger through the postitive crankcase ventilation system and is not due to a leaking seal.

    Anyone tried the grooved bearings that ET sells? The grooved design is supposed to provide better oiling & I'm just wondering if they have a longer wear life than others available.

    Another Q...I noticed the replacement bearings from ET are made of a bronze alloy & have the same yellow color as the R&D & OEM bearings. My Riva shaft had a gray colored bearing, so I'm wondering if theirs is made of a different material. Just a guess, but it would seem that you'd want a bearing made of a soft material so that they will wear instead of wearing the aluminum housing. Has anyone using the Riva bearings noticed any wear on their shaft housing.

    Is anyone selling the c-clips that hold the bearing(s) in place. I know mine are worn on the sides. Brought this up a few months back with no success.
