Honda Yamaha Motorcycle Valve Adjustment Tool. This valve tappet adjustment tool holds the tappet screw while the locknut is tightened during valve-clearance adjustment. Use during valve-service work after confirming the adjuster square, socket size, or shim access style. Use the correct wrench and driver size so the tappet setting does not move while the locknut is secured.
