NHTSA recall 18V730000
Engine And Engine Cooling · Yamaha Motor Corporation, USA
Details
What's wrong: The engine oil line flare nut may be insufficiently tightened, allowing oil to leak onto the rear tire.
Why it matters: An oil leak onto the rear tire can cause a loss of control, increasing the risk of a crash.
The fix: Yamaha will notify owners, and dealers will inspect the flare nut connection. If oil is not leaking, the nut will be tightened. If oil is leaking, the engine oil line will be replaced and the flare nut will be tightened, free of charge. The recall began October 31, 2018.
