Stop struggling with "starter slip" on your big-bore build. The RDLN High Performance Starter Clutch is a massive durability upgrade over the standard factory unit. While stock clutches rely on a weak 3-roller system, this RDLN unit features a 20-sprag "one-way" bearing design. This dramatically increases the surface contact area, allowing your starter motor to grip and turn over high-compression engines (150cc to 232cc) without the dreaded "clanking" or slipping of a failing bendix.
This starter clutch fits the "Large Format" GY6 engine series (125cc/150cc/170cc). It is a direct fit for 152QMI and 157QMJ-based engines found in:
Mechanic's Note: If you have installed a 170cc or larger Big Bore Kit, a standard starter clutch is your weakest link. To ensure a long life for this 20-sprag unit, always check your Starter Idle Gear for chipped teeth before installation. We highly recommend using Blue Loctite on the mounting bolts to prevent them from backing out inside the flywheel.
