@claws The Keihin carb is probably also fake. Most carb's are fake on eBay etc. If you order one directly from Yamaha, then it's most probably OEM, but will be double the price of the fake.
@Calum yea i know the disadvantages but its actually going to be cheaper to get an inner rotor kit than to get a brand new stator and i don't know if i would trust ebay
