I am in the process of mounting a 49 cc HS motor in a Genesis Onex bike. Anyone here have experience with that mount? The frame down tube is 1.750 Dia. that is way bigger than the radius in the motor mount. The mounting plate will require redrilling and the piece that fits the frame will interfere with the mounting holes. I would like to have the motor lower in the frame but I don't think it is possible as it is now it may be necessary to move the motor to check the oil. A different air cleaner and exhaust pipe may give me more room. I am trying to grind out the motor mount to fit the frame, very slow going. I have a die grinder and a drill press and lots of hand tools but that is it. If one of you has done this mount I could use some help. Thanx
