On my 650 project I can't get the cam chain tick to go way. This is a 79 motor with the solid adjust type tensioner. I took the valve cover off and got the cams lined up and the slack out of the chain and then set the tensioner(several times now). The cam chain clanks at low rpm and under accelleration. Between 2 to 4K on the tach it runs pretty smooth, over 4k and I can hear it again but fainter. I have also tryed a new type ball-lock tensioner (of an '80 model) with the same results. So is this an indication that the chain is shot? Is there something I am missing since I have never owned a 650 before The motor runs very strong otherwise. The valves all have about .004" clearnce, on the tight side but still in spec, no reason the valvetrain would make noise...
If I knew what I was doing all the time life wouldn't be any fun.
