I know there has been post after post of cam chain adjustments but I can't seem to find one on the 2008/2009 450. Looking at the manual it tells you how to install the adjuster but not how to actually adjust the tension on the chain. This is my first time messing with one of these and it looks to me like it is an automatic tensioner. All there is a bolt cap and spring. Can someone help a 4 stroker newbie out with this?
