Engine Compatibility Notice
Unfortunately, the 163QML and 161QMK engine platforms have too many manufacturer-specific variations for us to reliably provide fitment support.
While many parts may appear similar, critical dimensions and components can vary significantly between manufacturers, making compatibility difficult to verify.
For this reason, we currently do not offer support, fitment assistance, or guaranteed compatibility for these engine families.
We currently focus our support and product development on:
- GY6 50cc (QMB139)
- GY6 125cc (QMI152)
- GY6 150cc (QMJ157)
If you are unsure which engine you have, please contact us with photos of your engine and VIN information before ordering.
