The FS Racing clutch is a 54mm clutch. This size is commonly found on most 1/5 cars and Go-Ped scooters. This clutch features an all metal construction for maximum life and reliability. The included spring is set for a popular 8000 RPM engagement point.
With the all metal construction this clutch will have a break-in period of thirty minutes to one hour before optimal performance. Regular inspection of the clutch shoes and clutch bell are still suggested. This clutch uses an 8mm hole and is a direct replacement for Zenoah clutch shoes. When used with a CY clutch mount, the Zenoah clutch hardware must be used (two GT285 mount bolts, two GT287 shim washers, and two GT288 belleville washers). This clutch shoe assembly will fit all CY and Zenoah engines 23cc-34cc when used with the Zenoah clutch hardware.
