💡 Why do pit bike engines suffer from worn cam chain tensioners causing rough idle issues?
These components manage chain slack which keeps valve timing precise during normal operation.
- Older chains stretch leaving slack that ruins valves and head gaskets quite rapidly.
- Fresh roller kits restore proper clamping force to prevent mechanical issues easily.
