I got my 81 back from getting a top end rebuild and have a very loud top end tic. I had a scored piston so we got new 50mm over pistons for 650 central. I have run the valves and they are set to my books spec. I just checked the cam chain and it was a bit tight so I have adjusted it so the plunger is to the end of the adjuster nut. Now when I was adjusting, I started the motor and you can see the plunger moving. So I put my finger on the plunger and push (while running) and the noise almost goes away. So what is the problem if the chain is adjusted correctly?
