GY6B Starter Clutch for GY6 150cc Scooters with 16 Inch Wheels
The different brands like CF Moto E Charm, ITA 150 with 16 Inch Wheels that have a GY6 engine use a different starter clutch as well as a few other parts than a normal GY6 150 engine.
The fact that these have 16 Inch wheels calls for a different engine case that is larger so larger parts are needed which do match a CN250 engine fo rthe starter Clutch and a few other parts like the belt, variator, weights the head is also different as well as exhaust mount.
