How do you check the timing on a Harley Davidson?

Once the valve opens and closes, start watching for a vertical line on the flywheel through the timing hole. Stop the rotation when the mark is centered in the hole. Rotate the engine in the normal direction of rotation and never back the engine up. If you pass up the right spot then you have to go around again.
