Ok, a buddies quad jumped time and bent the valves. We replaced the valves, got a new tensioner, and pit a crf450 timing chain in it. He has stock rocker arms and a white brothers cam. It is one of the splined cams and I guess the splines are a little wore cause the flange wiggles a little on it. We got it all done and it was fine. Rode a few times, and I noticed I heard the valves, so I told him I would readjust them. Took it down, checked them and they were good, but I adjusted them anyway. Put it back together and it still clicked.
I got to listening and it sounded like the noise was coming from the chain side. I checked the valves again and they are fine. When you are turning the motor over by the crank, you can hear a click everytime the valves start to come up, ex. or in.. Not when they close, but when they start to close from wide open. I don't know what it is and just wanted ideas, could the chain be lose or what?
