My cousins 400ex tick comes in and out and it is driving me crazy. I checked the valves twice, cam chain and tensioner. what else could it be? It is forsure coming from the cam-chain side up top. He got a 440 kit and stage2 cam he is going to put in soon and we want to find what the tick is before we dive into it so we can take care of it.
