{{Note|type=warn|text='''Attention:''' The valve clearance is to be adjusted only on a cold engine.}}
# Remove the valve rocker cover after loosening the two socket screws
# Rotate the engine twice counter clockwise and enjoy the movement of the valves. Continue turning the propeller counter clockwise until you feel compression, then turn it another 1/4 turn. Both valves should be just closed and the piston at the top dead centre (TDC).
# The correct clearances are between 0.04 mm and 0.10 mm between the rocker arm and the valve. A 0.04 mm feeler gauge (the thinner one) can be inserted, a thicker one (0.10 mm) cannot.
# If the gap is narrower than 0.04 mm or wider than 0.10 mm, carefully loosen the lock nut on the rocker arm with a 5 mm wrench; turn the adjusting screw to increase the clearance about half a turn counter clockwise. Insert 0.04 mm feeler gauge between the rocker arm and the valve and gently screw the adjusting screw (clockwise) until it hits the feeler gauge.
# Tighten the lock nut again. Remove the feeler gauge, crank the engine a few times and check the valve clearance again
# Finally, screw the valve cover back on.

Pozor: Ventilová vůle se nastavuje jen na studeném motoru.
