result in an unsafe riding condition.
- Tighten the chain adjustment nuts.

Drive chain, chain guide, chain slide, and rear sprocket
When the chain has worn so much that it is more than 2% longer
than when new, it is no longer safe for use and should be replaced.
Whenever the chain is replaced, inspect both the engine pinion and
rear sprocket, and replace them if necessary. Worn teeth will cause
the chain to wear more quickly.
