Frequently Asked Questions

Q: How do I know if the 80T #219 sprocket is the right size for my kart?

A: Choosing the right tooth count depends on your engine, track layout, and desired power band. An 80T sprocket is typically used to increase acceleration out of corners or to compensate for specific track lengths. Always check your gear chart to ensure this ratio aligns with your engine's RPM range.

Q: Is this sprocket compatible with #35 chains?

A: No. This is a #219 pitch sprocket and is only compatible with #219 racing chains. Using a #35 chain will result in improper fitment and potential drivetrain failure.

Q: How do I ensure the sprocket is installed securely?

A: The Black Diamond sprocket features an integral keyway designed for a precise fit on your axle hub. Ensure your hub key is in good condition and tighten the sprocket bolts in a star pattern to ensure even pressure and eliminate any wobble.

Q: What maintenance is required for an aluminum sprocket?

A: Regularly inspect the teeth for signs of "hooking" or excessive wear, which indicates the sprocket is nearing the end of its life. Keep the sprocket clean of debris and ensure your chain is properly lubricated and tensioned to extend the life of both the sprocket and the chain.
