I have a Yamaha xt 500 1980 motorbike and need to reset the valve and cam timing. What needs to line up? How do i set cam position and timing?
You didn't say WHY the cam / valve timing needs to be reset. For some reason I get the feeling someone told you that resetting was needed and so you are asking how. Obviously, you may have installed new pistons and that is why the resetting is needed. In either event, when the cam timing is set the valve timing is also set. Other than adjusting valve lash, setting the cam sets the valve timing. Below is a web site where you can do a free download of a factory service manual. The process is not hard but having a manual will be more help and faster help than I can give online.

Testimonial: "Thanks for your reply. I've been to the web site before and downloaded the manual already. It does not really cover the situation I have. There also seems to be a lack of compression with the bike. A friend has lent me a workshop manual so I will try that in the mean time. Thanks again "
