GY6 Parts Store

This page covers parts for GY6 engines, the 4-stroke engine used in many 50cc to 150cc scooters, mopeds, go-karts, ATVs and dune buggies, plus 250cc go-kart and buggy engines. We carry 24 mm carburetors with electric choke for 125cc and 150cc engines, carburetor repair kits, automatic chokes, ignition coils, CDI modules, 8 coil stators, 4-pin rectifiers, 12V starter motors, fuel pumps, intake manifolds, air filters, kick start gears, front disc brake calipers and handlebar switches.

GY6 parts are matched by engine size and engine code. The 50cc GY6 is the 139QMB (also written QMB139), the 125cc is the 152QMI and the 150cc is the 157QMJ, and the code is stamped on the engine case. Many 125cc and 150cc parts interchange, while 50cc parts are different, so confirm your engine size before ordering. Can't find your part? Contact us with a photo of the old part, and we'll help.
