A must-have shop tool for any GY6 CVT service. The 101 Octane Variator Locking Tool bolts to the engine case and locks the starter gear in place, letting you break loose the large variator nut safely with hand tools — no impact wrench required. The plate design also doubles as a piston stopper, minimizing the risk of piston damage during service. Includes mounting bolts, nuts, and zinc-plated spacers (spacer color may vary between gold and silver — no effect on function).
