    Has anyone encountered an issue with the cam chain (timing chain?) tensioner failing?

    One of my CRF's has a knocking/rattling noise coming from the engine. Rather subtle, but noticeable enough to bug me. Online searches indicate it is the tensioner that has failed, and that it's a rather common issue.

    Anyone else have this? How did you resolve it?

    See video.

    I had to replace them on another Honda bike at 50,000 kilometres. They are not considered defective and are a wear-and-tear item on the bike. I think replacing two on the other bike was about $200 CDN, so is likely cheaper on our CRFs.

    I observed a similar rattle on my low-mileage CRF250L which had done only 600 mls.
    As the tensioner is about EUR 110 in Germany, I bought one in the UK for only 28 EUR including tax and shipping.
    Unfortunately it hasn't arrived yet so I can't tell wether it solved the issue or not.
    The price in Thailand is 402 BHT (10,80 €) by the way... :eek:
