Look closely at the box.

Ordered a 440cc motor and a 439cc showed up. Doesn’t seem like a big difference but the 439cc only has 7 cover plate bolts and the 440cc has 10 and is much stronger. I never took possession of the motor yet later that day they charged my credit card. Had to wait a week for a refund to go looking for a replacement motor. BTW They showed the 10 bolt pattern in the description.
