5.5.4 Checking and adjusting valve
clearance
1. Clean the surface of the cylinder head cover (1).
2. Remove the bolts (2) and take off the cylinder
cover (1) and the gasket (3).
3. Turn the engine in the rotation direction until the
first rocker arm (4) has fully opened the outlet
valve.
4. Check the clearance at the second rocker arm (5)
with a feeler gauge (6).
5. Turn the engine in the rotation direction until the
second rocker arm (5) has fully opened the intake
valve.
6. Check the clearance at the first rocker arm (4).
The valve clearance of the inlet/outlet must be
0.10 mm.
7. If the valve clearance has to be corrected, release
the bolt (7) and turn the hexagon nut (8) so the
feeler gauge (6) can be pulled through with a
barely perceptible resistance after the bolt (7) is
tightened again.
8. Reinstall the cylinder head cover (1) with the new
gasket.
Remove the access plate from the
canopy roof to perform this action.
