What's wrong?
The camshaft retainer plate on 2018-2022 Yamaha Xmax scooters helps hold the camshaft in position inside the engine. The camshaft opens and closes the engine's valves at the right time, so the retainer plate and bolt have to keep it seated while the engine is running.
On affected scooters, Yamaha found that the mounting structure for the retainer plate did not provide enough bolt tightening force. That lets the camshaft retainer bolt loosen and stop securing the camshaft correctly. If the camshaft shifts out of position, valve timing is disrupted and the engine can stall.
Owners are expected to notice engine noise, poor performance, a degraded running condition, or hard starting before an engine stall. Those signs mean the engine is no longer running normally, so the scooter should be checked by a Yamaha dealer before further use.

What happens at the repair
Do not ride the scooter until the recall repair is complete. At the dealer, a Yamaha technician installs a new camshaft plate kit so the camshaft retainer bolt is secured as intended. The repair is free under the recall, with parts and labor covered by Yamaha. Once the kit is installed, ask the service desk to confirm the recall campaign is closed for your VIN before you ride again.
