Hello.  I am a new member who just discovered this site. I have a 1982 Honda Nighthawk CB750sc. I downloaded the manual (thank you for that) and I have a haynes manual. They don't seem to be specific to my bike when it comes to adjusting the cam chain and the chain between. The one says to start the bike and let it idle then loosen both cap nuts in the back of the cylinder head a half a turn. I only have one cap nut back there. In the front it says to back off the lock nut and then the other nut/bolt. That seems to be for the chain that runs in between. My question is this: Should I be looking for another cap nut in the back? It is a dohc so why is there only one? Hope you can guide me. My bike is getting noisy, particularly at 5000rpm. Thanks, Jeff Hebert.
