Arctic Cat F 800 LXR User Manual

A. TAN or LIGHT BROWN insula-
tor indicates correct spark plugs
(heat range).
B. LIGHT GRAY or WHITE insula-
tor indicates over-heating of the
engine. This condition is caused by
a too lean condition or incorrect
spark plugs (heat range too hot).
C. BLACK insulator indicates fuel
in the combustion chamber is not
burning completely. This condi-
tion is caused by a too rich con-
dition, too much oil, or incorrect
spark plugs (heat range too cold).
 NOTE: If the center electrode insu-
lators are light gray, white, or black
and if the oil-injection pump synchro-
nization
, and ignition timing are cor-
rect, different heat-range spark plugs
may be necessary. Authorized Arctic
Cat Snowmobile dealers have
detailed spark plug information. Con-
sult a dealer before changing spark
plugs, as incorrect heat-range spark
plugs could cause poor engine per-
formance or engine damage.
Checking/Adjusting
Valve Clearance (1100
cc Models)
After 5000 miles or prior to seasonal
storage, valve clearance should be
checked and adjusted as necessary.
 NOTE: Take the snowmobile to an
authorized Arctic Cat Snowmobile
dealer for inspection and service.
This service is at the discretion and
expense of the snowmobile owner.
Checking/Adjusting
APV Cables (800 cc
Models)
Proper cable adjustment is critical to the
operation of the APV system. Although
inspecting cable adjustment is recom-
mended every 1000-2000 miles, the cable
should not need adjustment often. To
check the cable adjustment, use the fol-
lowing procedure:
0745-819
1. Using a small needle-nose pliers,
remove the servomotor cable holder.
0745-823
2. Using an adjustable wrench, rotate
the servomotor actuator counter-
clockwise to loosen the cable; then
pull the cable housings down and
out of the servomotor.
CAUTION
If a spark plug is light gray, white, or
black and another is tan or light
brown, take the snowmobile to an
authorized Arctic Cat Snowmobile
dealer for inspection and service. If
not under warranty, this service is at
the discretion and expense of the
snowmobile owner.
CAUTION
It is critical that the checking/adjust-
ing valve clearance be done at the
recommended intervals or severe
engine damage may occur.
