250 Yz250 Crankcases

[antharg96]

Hi, I am into the process of rebuilding my bottom end but my crank cases do not match. I know that other years from 96 can be used because that is what the previous owner has done.
Does anybody know what cases will fit into this frame as i need to get matching cases as the rest of the bike is mint and these mismatched cases will really let it down. I am strugglimg to find the 96 cases but thrre's plenty of other years on ebay etc.
Any info will be appreciated

This is a question for @PALMER84ONE.
He will know. There’s also @ossagp who has a vast knowledge of motorcycles.

1988 through 1996 Yamaha YZ250 all used the same left and right main cases.

Good luck as they are becoming harder to get.

I still have a gear set for a wr of that vintage if anyone wants it.
