Hello! I have just reinstalled the camshafts on my 1983 Yamaha XS 400 E12 with a DOHC engine after a gasket change. When rotating the camshafts together with help from the ACG rotor, the cam chain seems quite slack just when the cams hit TDC. Apart from that the cam-chain is tense when it isn't in TDC or 180 Degrees from TDC. The cam chain tensioner and the cam chain guide are both installed.
So my question is this simple, Is the cam chain supposed to be slack when it's in TDC?
