If the gap is found to be too small or too large, reset the valve clearance as follows:

1. Carefully loose the locknut on one rocker arm with wrench.
2. Turn adjusting screw approx. 1/2 turn counter clockwise to open gap.
3. Insert 0.04 mm feeler gauge between valve stem and rocker arm, and gently turn adjusting screw clockwise with a screwdriver until it stops.
4. Re-tighten the locknut while holding the adjusting screw with a screwdriver.
5. Remove 0.04 feeler gauge, rotate prop through exactly two turns and re-check gap. If the valve clearance is correctly adjusted, check other valve and adjust if necessary. Then replace rocker cover.
6. Check the other cylinder and adjust, if necessary, in the same way
