Go-Kart Centrifugal Clutch Kits with 3/4- or 1-Inch Bore and #35 or #420 Chain Options – GYMMEDS
A go-kart centrifugal clutch transfers power automatically as engine speed rises in a compatible mini-bike, kart or small-equipment drivetrain. GYMMEDS offers three bore, sprocket and chain combinations for matching the crankshaft and final-drive setup.
The fully documented option uses a three-quarter-inch bore, 12-tooth sprocket and number 35 chain for compatible two- to 6.5-horsepower engines with a three-sixteenths-inch keyway. It includes the clutch, chain, bolt, washer kit, wrench and two set screws.
