This video shows how to disassemble, inspect, and reassemble the CVT transmission systems popular on motor scooters. This includes the variator, rollers, drive belt, clutch, clutch bell, torque driver, and more. Complete disassembly and reassembly. This video shows a 1E40QMB / Jog / Minarelli 49cc two-stroke, but the basics apply to a wide range of scooters and some youth ATVs and karts. Sorry, I'm not a good narrator.
