the muffler (see Figure 53).
Figure 53 – Spark Arrestor Clamp
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
bottoms out.
b - Place the spark arrestor band clamp over the

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°.
