! WARNING
Tighten the cap screws according to
specifications to prevent unexpected
"movement" of the handlebar during
operation over rough terrain. DO NOT
position handlebar so steering (maxi-
mum right/left turning capabilities) or
throttle and brake controls are affected.

2. Adjust the handlebar to operator's
desired position, tighten the cap
screws evenly to 2.0 kg-m (15 ft-lb),
and check steering for maximum
right/left turning capabilities.
CAUTION
Do not rotate the handlebar to a posi-
tion that allows air to enter the brake
system.

Exhaust System
The exhaust system is designed to reduce
noise and to improve the total perfor-
mance of the engine. If any exhaust sys-
tem component is removed from the
engine and the engine is run, severe
engine damage will result.
Air-Intake Silencer
Used in conjunction with the fuel intake
system is a specially designed air-intake
silencer. The purpose of the silencer is to
quiet the intake of fresh air. Since the fuel
intake system is calibrated with the air-
intake silencer in place, the engine must
never be run with the silencer removed.
Performance will not be improved if the
air-intake silencer is removed. In con-
trast, severe engine damage will occur.
These snowmobiles are not designed
to be operated in dusty conditions.
Operating the snowmobile in dusty
conditions
engine damage.
Cooling System
These snowmobiles are equipped with a
closed liquid cooling system for engine
cooling. The cooling system should be
inspected daily for leakage and damage.
Also, the coolant level should be checked
0747-828
daily. If leakage or damage is detected,
take the snowmobile to an authorized
Yamaha Snowmobile dealer for service.
If not under warranty, this service is at
the discretion and expense of the snow-
mobile owner.
When filling the cooling system, use an
ethylene glycol-based coolant/water mix-
ture which will satisfy the coldest antici-
pated weather conditions of your area in
accordance with the coolant manufac-
turer's recommendations.
NOTE: If operating on ice or hard-
packed snow conditions, it is recom-
mended that Ice Scratchers be
installed to reduce wear strip wear
and engine overheating.
For checking/filling cooling system, refer
to Coolant Level sub-section in the Main-
tenance section.
