ENGINE
ADJUSTING THE VALVE CLEARANCE
The following procedure applies to all of
the valves.
NOTE:

• Valve clearance adjustment should be
made on a cold engine, at room tem-
perature.
• When the valve clearance is to be mea-
sured or adjusted, the piston must be
at top dead center (TDC) on the com-
pression stroke.
1. Remove:
• bottom cowling
• front cowling
• rear cowling
Refer to “COWLINGS”.
• fuel tank
• air filter case cover
Refer to “FUEL TANK AND AIR FIL-
TER”.
• air filter case
• throttle body assembly
Refer to “ELECTRONIC FUEL INJEC-
TION” IN CHAPTER 6.
• radiator assembly
• thermostat assembly
Refer to “RADIATOR AND THERMO-
STAT” in chapter 5.
2. Disconnect:
• camshaft sensor coupler
• ignition coil couplers
3. Remove:
• ignition coils
• spark plugs
•
cylinder head cover
1

• cylinder head cover gasket
4. Remove:
• pickup coil lead holder
1

• pickup coil rotor cover
