PROX Clutch Cover Gasket for YAMAHA YZ 250 1990-1998

On YAMAHA YZ 250 from 1990 to 1998, the PROX 19.G2390 clutch cover gasket fits in place of the original part. On the clutch side, the cover holds in the gearbox oil. Its gasket crushes when tightened: refitting the old one means risking an oil leak onto your boot or into the engine.
