Hey... if you you're standing on the bike with the feet on the floor and the engine off, push your front suspension up and down hard...
My XT600E stock front suspension started making a "knock" sound when I hit a small bump on the road or when braking so I changed it...
It was when I made that same thing I said on the first phrase that I found out the noise was coming from the suspension and not the engine...
