Hey guys, I'm new here and I have a question for you. I put a new head on my 1986 Honda 250sx and timed the cam chain according to the manual. With the T lined up with it's mark and the two notches lined up for the cam sprocket and all that good stuff per the service manual. When I put my chain tensioner back in next it moved my cam sprocket timing marks off just a bit. Looks like maybe a tooth worth off but the manual doesn't mention that happening. I put the valve cover back on and adjusted the valves and I can feel it suck on the intake stroke when I turn it with a ratchet. My question is the timing marks. Is that normal for them to be off after the tensioner is installed or did I do something wrong. I went by the manual but just want to be sure. Thanks for any help
