Manual models use a wet clutch pack. In both cases, springs, weights, bearings, sheaves and plates all have to work together.\u003c\/p\u003e\u003cp\u003eWorn parts change how the clutch engages and shifts. Replacing them with the Suzuki parts keeps the drive working the way it was calibrated at the factory.\u003c\/p\u003e\n\u003ch2\u003eSigns of Wear\u003c\/h2\u003e\n\u003cp\u003eLook for a glazed or cracked belt, grooved sheaves, worn rollers or weights, a notched basket or burnt plates.
