So I did a little bit of work on the top end of my 77 cb550f (new rings, valves, gaskets, o-rings) and now upon re-assembly not only did I have a hell of a time even getting the cam chain back onto the cam sprocket, but now I can't get enough slack out of the chain to get the sprocket with the chain on to go up onto the lip of the cam shaft where it needs to be.
The tensioner is all the way back, the chain is on the lower sprocket, the motor is set to TDCC, everything seems to be together right, but I will not go.
If anybody else has run into this please help me out.
Thanks
