Engine Crankshaft Keyway – Honda GX Series Go Kart Engine

Aftermarket replacement crankshaft keyways for Honda GX series go kart engines. The keyway is the small but critical component that locates the centre clutch, drive sprocket, or other shaft-mounted components onto the engine crankshaft. It's one of those parts you don't think about until it shears — and when it does, the result is immediate and unmistakeable. The engine revs perfectly, the kart doesn't move. On a busy rental track that means a kart out of rotation until it's fixed.

The good news is it's one of the quickest and cheapest fixes on the entire kart. Keep a pack on the shelf and it's a five-minute turnaround rather than a problem that ruins your day.
