This Mini Moto Flywheel Fixing Bolt & Washer set is essential for owners of 47cc and 49cc pocket racing bikes who need a secure, durable mounting solution for their engine's flywheel. It provides a precise fit to ensure engine stability during high-RPM operation, though users should ensure their specific crankshaft threading is compatible before installation to avoid cross-threading.

No, this set is specifically designed for 47cc and 49cc mini moto engines and may not be compatible with larger engine types.
This set includes the bolt and a standard washer. We recommend using a thread-locking compound to ensure security during operation.
The bolt features an M8 thread diameter.
It is not recommended. Use a hand tool to avoid over-tightening or stripping the M8 threads.
The cap nut is 12.85 mm in length.
Clean the crankshaft threads with a wire brush and check for cross-threading damage.
Ensure the washer is correctly seated and the bolt is tightened to the manufacturer's specified torque.
To install this set, first ensure the crankshaft thread is clean and free of debris. Slide the washer onto the bolt, then thread it into the crankshaft by hand to ensure it is correctly seated before using a socket wrench to tighten. Avoid using impact tools, as these can strip the M8 threads. Periodically check the bolt for signs of wear or stretching during your regular maintenance intervals. This part is compatible with most 47cc and 49cc mini moto engines, but always compare the 12.85 mm length against your existing hardware to confirm suitability for your specific engine casing.
