Important Gen 3 / Gen 4 Fitment Check
YX and Zongshen clutch assemblies vary by engine generation. Some Gen 3 baskets use a removable kick-start centre gear, while some later Gen 4 versions use a fixed centre gear. Do not order by engine capacity alone.
- Confirm the existing clutch uses 5 friction plates.
- Compare the rear of the clutch basket and the kick-start centre-gear arrangement.
- Compare the 67T outer basket gear, inner hub and pressure plate with the original.
- Check the shaft fitment and centre spline before installation.
- For Zongshen 140 engines, compare the complete clutch assembly physically before ordering because several generations were produced.
