ADJUSTING THE VALVE CLEARANCE
The following procedure applies to all of the
valves.
TIP
• Valve clearance adjustment should be made
on a cold engine, at room temperature.
• When the valve clearance is to be measured or
adjusted, the piston must be at top dead center
(TDC) on the compression stroke.
1. Remove:
• Left side panel
• Right side panel
• Front fender
• Footrest board
• Air filter case
Refer to “GENERAL CHASSIS” on page 4-1.
2. Remove:
• Intake tappet cover “1”
• Exhaust tappet cover
• Camshaft sprocket cover “2”
3. Disconnect:
• Spark plug cap “1”
4. Remove:
• Spark plug “2”
5. Remove:
• Timing mark accessing screw “1”
• Crankshaft end accessing screw “2”

a. Turn the crankshaft counterclockwise.
b. When the piston is at TDC on the compres-
sion stroke, align the “I” mark “a” on the AC
magneto rotor with the stationary pointer “b”
on the AC magneto cover.
TIP
To position the piston at TDC on the compres-
sion stroke, align the “I” mark “c” on the camshaft
sprocket with the stationary pointer “d” on the
cylinder head, as shown in the illustration.
c. Measure the valve clearance with a thickness
gauge “1”.
