thanks ego, but i got plenty on orings.now if you want to be useful go out to your garage,get out your monkeywrench & hammer and start taking sidecase off your motor.seals are between waterpump bearing and impeller.let me know when you have #'s.you better start soon its getting late and you might need to borrow your neighbor's crowbar. P.S.my dog thinks im crazy everytime he go out in backyard i follow right behind him with my nose plug and rubber gloves

Here is a number off of the oil seal, actually there is several numbers printed on the Yamaha package. 93102-12321, K010419a, 500721.
Try them and see which one is the actual part #.
Sorry I don't have the outer seal #. These are #s off of a 98 YZ400. I'm assuming they are the same on newer models.
