Frequently asked questions

How do I know my sprocket needs replacing?

Look for hooked or worn teeth, visible grooves where the chain rides, or a chain that derails frequently. A worn sprocket accelerates chain and bar wear.

Do I need to replace the clutch drum with the sprocket?

Inspect the drum bearing surface. If it spins freely with no play, the drum is fine. If the bearing feels rough or the drum is scored, replace both together.
