4. Loosen the clamp holding the spark arrestor onto
the muffler.
5. Slide the spark arrestor band clamp off the spark
arrestor screen.
6. Pull the spark arrestor screen off the muffler
exhaust pipe.
7. Using a wire brush, remove any dirt and debris that
may have collected on the spark arrestor screen.
8. If the spark arrestor screen shows signs of wear
(rips, tears or large openings in the screen), replace
the spark arrestor screen.
9. Install the spark arrestor components in the
following order:
a. Place spark arrestor screen over the muffler
exhaust pipe. Push on the screen until it fully

CHECKING AND ADJUSTING VALVE LASH

CAUTION
Checking and adjusting valve lash
must be done when the engine is cold.
1. Remove the rocker arm cover and carefully remove the
gasket. If the gasket is torn or damaged, it must be
replaced.
2. Remove the spark plug so the engine can be rotated
more easily.
3. Rotate the engine to top dead center (TDC) of the
compression stroke. Looking through the spark plug
hole, the piston should be at the top.
4. Both the rocker arms should be loose at TDC on the
compression stroke. If they are not, rotate the engine
360°.
5. Insert a feeler gauge between the rocker arm and the
valve stem and check for clearance (see Figure 20). See
Table 2 for valve lash specifications

6. If an adjustment is required, hold the adjusting nut and
loosen the jam nut.
7. Turn the adjusting nut to obtain the correct valve lash.
When the valve lash is correct, hold the adjusting nut
and tighten the jam nut to 106 in-lb (12 N•m).
8. Recheck the valve lash after tightening the jam nut.
9. Perform this procedure for both the intake and exhaust
valves.
10. Install the rocker arm cover, gasket and spark plug.
