The official notice
Defect
On certain motorcycles, incorrect programming may cause the engine to stall. This could happen when downshifting (if the clutch lever is not fully pulled in) or when the throttle is opened from idle. Also, the engine warning light may not turn on when a part fails. This problem could also cause the engine warning system to turn on and give limited throttle response. Note: This recall replaces recall M22-014 (Transport Canada Recall No. 2022-099). Vehicles that received a software update under that recall also require this repair.
Safety Risk
A sudden engine stall could increase the risk of a crash. A sudden lack of acceleration could surprise the rider, and in certain situations, could increase the risk of a crash.
Remedy
Yamaha will notify owners by mail and advise you to take your motorcycle to a dealer to update the engine control unit (ECU) software.
