So my Drz has been making a noise that has slowly gotten louder over the last year or so.
It sounds like it is either the cam chain, or valves. A ticking that the Drz is known for, but it is just getting louder. I have checked the valves recently and are in spec, and the cam chain looks to be in perfect working order.

I am stumped as to where the noise is coming from. So short of a motor tear down, what have you guys concluded about the mysterious Drz sewing machine?

My friends engine on his DRZ was making a little more noise than usual and he just threw in a manual cam chain tensioner and that solved the issue.

So the chain just becomes too loose for the auto tensioner to work properly? It looks like it would hit the chain guide inside of the head.
