I have an '01 WR250F. I was cleaning the carb and pulled it apart mid body not knowing that you're not supposed to do that. I posted yesterday looking for the seals that were shot. Where can I get these carb parts? Couple of replies and I've learned that the needed seals are available, only for 2003 and up. The seals I see look close and the ads say " Will not fit 98-02 Yamaha". I need to know if a carb from an 03 or later bike will fit mine. Has anybody done this swap? I've looked on ebay and see used carbs. No way will I buy an 01 or 02 carb if some parts are not available.
