It’s a straightforward OEM-style replacement engineered to engage automatically at higher RPMs, so you regain drive to the rear sprocket on vehicles such as go-karts, mini choppers, and utility equipment.\u003c\/p\u003e\n\n\u003ch3\u003eWill this clutch fit my 97cc mini bike engine?\u003c\/h3\u003e\n\u003cp\u003eCompatibility depends mainly on shaft diameter, chain size and mounting style. This unit uses a 5\/8\" bore and an 11-tooth sprocket cut for #35 chain; if your engine shaft is 5\/8\" (or you use a compatible bushing) and your drivetrain uses #35 chain, it will typically fit as a direct replacement.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/8\" (0.625\") internal bore — standard for many mini bike engines\u003c\/li\u003e\n  \u003cli\u003e11-tooth sprocket sized for #35 chain engagement\u003c\/li\u003e\n  \u003cli\u003eDesigned for ~97cc, 2.8 HP powerplants commonly found on mini bikes\u003c\/li\u003e\n  \u003cli\u003eMay require a key, washer or retaining clip consistent with your existing setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does this centrifugal clutch behave on startup and at speed?\u003c\/h3\u003e\n\u003cp\u003eThe clutch is centrifugal: it remains disengaged at low RPMs so the engine can idle without driving the wheels, and it progressively engages as revs rise.
