This sprocket was manufactured with two flaws, but is still will work on many go-karts or mini-bikes.
Defects:
Teeth were cut short (see alternate picture), the pitch (#40) is correct and will work with #40 chain.
Bolt holes are drilled with very little tolerance (may need reamed out to work with your hub)
No returns available for this product!
