Re: CB750 Valve timing
Typically, all you need to do is pull the chain tensioner to loosen the chain enough to reposition the cams. Are you sure the crank is @ TDC when you checked the camshaft position?
Also, if it's an automatic type tensioner, remove it and reset it before reinstallation. Your manual should have the details.
