Primary Chain Tensioner Assembly for Triumph 1963-72 650 Models
We are selling a new duplex primary chain tensioner blade assembly kit. Fits Triumph Twin 650 63-72. If you are rebuilding your clutch there are a few things you will need to check and possibly replace. The primary chain and tensioner are very important and need to be checked for over adjustment. If the tensioner has a rainbow shape it is time for a new one.
