The PetrolScooter Mini Moto Clutch Bell Bolts are essential replacement components designed for owners of 47cc and 49cc air-cooled mini motos, quads, and ATV racing bikes. These bolts provide a secure and reliable attachment for your clutch bell assembly, ensuring drivetrain stability during operation. While they are built for durability and precision, users must ensure their specific engine model's bolt hole depth matches the 19.78 mm threaded section to prevent overtightening or bottoming out during installation.

These are designed for standard air-cooled 47cc and 49cc mini engines. Please compare your existing bolts to the 19.78 mm threaded length to confirm compatibility.
The overall length of each bolt is 25.88 mm.
This set contains four bolts only; you should reuse your existing washers if they are in good condition.
Most standard mini moto clutch bells use four bolts, which is exactly what this pack provides.
No, these are specifically manufactured for air-cooled mini moto and quad racing bikes.
While a torque wrench is ideal, these small bolts are usually tightened by feel; avoid excessive force to prevent stripping the engine block threads.
Check the hole for debris or residual thread locker and ensure you are using the correct bolt hole for your specific clutch bell model.
Use a medium-strength (blue) thread-locking compound on the threads before installation and verify the bolts are tightened to the manufacturer's recommended torque.
Ensure your hex key is the correct size and not worn down; apply even downward pressure while turning.
Before installation, ensure the engine is completely cool to avoid thermal expansion issues. Remove the old bolts using the appropriate hex key, then thoroughly clean the threaded holes on the clutch assembly to remove any debris or old thread locker. Insert the new bolts by hand to ensure they start straight, then tighten them in a cross-pattern to distribute clamping force evenly across the clutch bell. Do not use high-torque power tools as these can strip the aluminum threads commonly found in small engine blocks. Regularly check these bolts during your pre-ride inspection to ensure they remain snug.
