Removable Seat
(Crossfire 800 Models)
These snowmobiles are equipped with a
removable seat. To remove the seat, use
the following procedure:
1. Inside the rear storage compartment
on the bottom of the seat-base, rotate
the latch cover away from the right-
side locking pin.
2. Lift on the back of the seat and move
it rearward to remove it from the
tunnel.
To install the seat, use the following pro-
cedure:
1. Slide the front of the seat into posi-
tion on the tunnel; then lower the
rear of the seat onto the locking pins.
2. Press down on the rear of the seat until
the retaining clips snap into place on
the locking pins; then rotate the latch
cover until it snaps into place on the
right-side locking pin.
Towing
If the snowmobile is to be towed by
another snowmobile, do not tow using
the loops in the skis. The tow rope should
be attached to the spindles.
Arctic Power Valve
(APV) System
This RPM controlled servomotor (servo)
actuated system adjusts the size of the
exhaust ports to provide peak perfor-
mance throughout the RPM range.
The system consists of an exhaust valve
assembly mounted to the exhaust side of
each cylinder and connected by adjust-
able cables to an electronic servo
mounted beneath the hood.
NOTE: The mounting location of the
servo will vary from model to model.
739-152F
At low RPM, the exhaust valves are held
in the DOWN position by return springs.
This gives the engine a “low port”
exhaust design calibrated to provide
maximum low RPM power and improve
fuel economy at trail speeds.
739-152G
At high RPM, the exhaust valves are
raised. This creates a “high port” exhaust
design calibrated to provide maximum
performance at high RPM.
739-152H
NOTE: The RPM ranges will vary
from model to model.
! WARNING
Make sure the seat is securely
locked in place or personal injury
may result.
CAUTION
The recommended engine oil to use
is either Arctic Cat APV Synthetic 2-
Cycle Oil or Formula SS Semi-Syn-
thetic Oil (see Gasoline-Oil - Recom-
mended Injection Oil sub-section in
this section). Any substitute may
cause an APV malfunction.
