F. On the XTZ, rotate the engine 270° to the TDC
position of the rear cylinder; then repeat steps
A-E for the rear cylinder.
3. Install the spark plug(s) and timing inspection plug;
then on the XTZ remove the cap screw and install the
crankcase end cap.
4. Place the two tappet covers into position making sure
the proper cap screws are with the proper cover.
Tighten the cap screws securely.
Testing Engine
Compression
To test engine compression, use the following procedure.
NOTE: The engine should be warm (operating tem-
perature) and the battery fully charged for an accurate
compression test. On the XT/XTX, throttle must be in
the wide-open throttle (WOT) position. In the event the
engine cannot be run, cold values are included.
NOTE: The seats and center console must be
removed for this procedure.
1. Remove the high tension lead from the spark plug(s).
2. Using compressed air, blow any debris from around
the spark plug(s).
3. Remove the spark plug(s); then attach the high tension
lead(s) to the plug(s) and ground the plug(s) on the cyl-
inder head(s) well away from the spark plug hole(s).
4. Attach the Compression Tester Kit.
5. While holding the throttle in the full-open position,
crank the engine over with the electric starter until
the gauge stops climbing (five to 10 compression
strokes).
6. If compression is abnormally low, verify the
following items.
A. Starter cranks engine over.
B. Gauge is functioning properly.
C. Throttle in the full-open position.
D. Valve/tappet clearance correct.
E. Engine warmed up.
F. Intake not restricted.
NOTE: To service top-side components, see Section 3.
7. Pour approximately 30 ml (1 fl oz) of oil into the
spark plug hole(s), reattach the gauge, and retest
compression.
8. If compression increases to normal, service the pis-
ton rings (see Section 3).
Spark Plug(s)
A light brown insulator indicates that the plug is correct.
A white or dark insulator indicates that the engine may
need to be serviced. To maintain a hot, strong spark, keep
the plug free of carbon.
ATV-0051
Adjust the gap to 0.5-0.6 mm (0.019-0.024 in.).
! WARNING
Always wear safety glasses when using compressed air.

CAUTION
Before removing a spark plug, be sure to clean the area
around the spark plug. Dirt could enter engine when
removing or installing the spark plug.
