Be warned
Color: 140CC 4 Stroke
Would not recommend buying this engine don't waste your hard earned money on it. Got one sent out came in pretty quick but couldn't not get running had spark and gas and air simple should start nope customers service was nice enough to send a second engine got running same day but always had clutch problems either was engaging all the way or at all even bought a different cable length to help nothing worked. Ending up getting to a point and it was fun till 🙃 the transmission let go of 3rd gear no matter the adjustment or cable u have that clutch will not full engage for a smooth change of gears and no information available to help you fix the problem spend ur money some place else do more research than I did ... show more
