The 2016 Yamaha XC155 has two recalls, the more serious being a primary sheave nut that can loosen and fall off, causing the engine to stall with no ability to restart, raising the risk of a crash.
The second recall involves cylinder head nuts that may not have been properly tightened and can loosen over time, allowing coolant to leak onto the spark plug. A coolant-fouled spark plug can cause the engine to stall at idle and possibly not restart, also raising crash risk.
