Good To Know

Q: Is this an original Yamaha part? A: It is an aftermarket timing chain damper built to OEM cross-reference 6D3-12251-00-00. It is not an original Yamaha product.

Q: When should the damper be replaced? A: Replace it when the chain guide shows cracking, deep grooves, or looseness during a timing chain or top-end service. Inspecting it whenever the valve cover is off helps catch wear early.
