I have done a search of the Yamaha forum, and didn't find the proceure to adjust the timing chain on my beast. Can anyone help? Thanks, Ron.

 

the timing chain tensioner is spring loaded and adjusts the chain tension automatically. its the big bolt looking thing on the left side of the cylinder next to the intake ports. if you want to see how far the adjuster is, just unscrew the big bolt and remove the spring, then unscrew the two hex screws and the depth of the plunger will let you know how far the chain is being pushed, so you can get an idea of chain stretch.
