I'm getting ready to sell my old bike finally. It's making a ticking noise.. Not sure if it just needs a valve adjustment or maybe a new timing chain? I'm not all that familiar with the engines yet since i've never had to crack this one apart. Xr's seem indestructable. I actually know someone who tried to blow one and couldn't.

Here's a video of the sound

Sounds like cam chain .. Have you adjusted the cam chain lately ..

 

Nope.. It's still got the origional in it from 1998 so that was my guess too hah but i'm not too experienced with them yet.

 

 

Thanks.. It worked but I snapped the damn bolt. I wasn't even putting it on that tight. I was using about half strength... I guess the metal weakened some over the years. Not sure how I'm gonna fix it now.
