8. Shut off the engine, and disconnect the timing
light and portable tachometer. Install the timing in-
spection cover (A, Figure 9).

Valve Clearance

Valve clearance measurement and adjustment
must be performed with the engine at room temper-
ature (below 35° C [95° F]).
The exhaust valve is located on the rear side of
the rear cylinder and on the front side of the front
cylinder.
NOTE
This procedure is shown with the en
gine removed from the frame for pho
tographic clarity. The valves can be
adjusted with the engine in the frame.
1. Remove the rider and passenger seats as de-
scribed in Chapter Fourteen.
2. Remove the fuel tank, air filter housing and the
surge tank (Chapter Eight).
3. Remove the cylinder head covers (Chapter
Four).
4. Remove both the intake (Figure 11) and exhaust
valve covers from each cylinder head.
5. Remove the timing inspection cover (A, Figure
9) and flywheel nut cover (B) from the alternator
cover.
NOTE
A breather plate is not used in the rear
cylinder head.

6. Remove the mounting screws (A, Figure 12)
and remove the cam sprocket cover (B) and its
O-ring from each cylinder head. When working on
the front cylinder, make sure the breather plate and
its O-ring (A, Figure 13) come out with the cam
sprocket cover (B).
7. Remove both spark plugs. This makes it easier to
rotate the engine.
NOTE
When a cylinder is set to TDC on the
compression stroke, the timing mark
on its cam sprocket may not precisely
align with pointer on the cylinder
head. On some models, the mark
could be off by as much as 1/2 tooth.
8. Use the flywheel nut to turn the crankshaft
clockwise until the rear cylinder is at top dead cen-
ter on the compression stroke. The rear cylinder is
at TDC on the compression stroke when the T-mark
(A, Figure 14) on the flywheel aligns with the cut-
out in the alternator cover (B), and when the timing
mark on the rear cam sprocket (A, Figure 15) aligns
with the pointer on the rear cylinder head (B).
