I have the engine out of my brat to replace the crank and rod bearings and I noticed the ring gear teeth are pretty chewed up.  I can't seem to find a new replacement anywhere.  Even just a new ring gear would be OK.  As a last resort I could rotate the ring gear but I would rather just replace the thing.  Anyone have any leads?

Used is what I have resorted to.

 

Thanks or the reminder , I need to swap mine for the same reason. And as you probably know already it'll always be on that chewed spot when you are in front of a crowd. Something most morons don't understand and they snicker as if your car is a pos.

Ended up just rotating the ring gear 90 degrees.  Working great so far.
