Service bulletin M2023-002

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

The 2015 ~ 2021 YZF-R1 and YZF-R1M Oil Strainer Cover has been changed due to procurement reasons. The magnesium Oil Strainer Cover is no longer manufactured and has been superseded to the current aluminum Oil Strainer Cover. As a result, when replacing the magnesium Oil Strainer Cover with the aluminum Oil Strainer Cover, the relating parts and service procedures will change. If the magnesium Oil Strainer Cover is ordered, it will automatically supersede to a kit part number once the current stock has been depleted. The superseded kit parts will include the new service procedures as well as all related parts.

The document
