Thanks for the answer. But I did a little more searching and found this post:
Not a big deal as long as you hear the starter spinning over.
DISCONNECT THE BATTERY , FINGERS GET EXPENSIVE.
*Drain the primary and you probably have to remove the rear floorboard to get the cover off.
*Remove the primary cover, make a template for the bolts from cardboard , draw a primary picture on it and stick the bolts in holes you make showing their position in the cover, there different lengths and can screw you up.
*You'll see the ring gear with the starter drive in the upper right of the primary area. (the small gear in the pic)
*Remove the bolt in the center after bending the lock tab down
*Remove the starter drive and replace it with the new one.Check the manual to see if blue locktite is recommended.
*Reverse the foregoing procedure and fill the primary with the proper amount of oil up to the bottom of the silver ring around the clutch basket with the bike straight up after putting on a new gasket and you're done. Use the HD gasket if you do it. The aftermarket gaskets tend to leak without the silicone bead on them.
So is it the gear in the primary or the clutch in the starter?
