Performance Tips

Operating a high performance snowmo-

bile requires a special attention that is not

required by a low performance snowmo-

bile. Often, a minor adjustment will

result in a large increase in performance.

This section is intended to highlight

minor conditions that adversely affect

performance and the adjustments needed

to correct them. Be sure, however, to

thoroughly read and understand this

entire manual especially the section on

spark plugs, track tension and alignment,

and suspension.

DRIVE BELT POSITION

Drive belt length, condition, and position are

all important for peak performance. To

check and adjust drive belt, remove the belt

guard; then use the following procedure.

NOTE: Removing/adding shim

washers may be done by the snow-
mobile owner if qualified to do so.
If the owner does not feel qualified,
take the snowmobile to an autho-
rized Yamaha Snowmobile dealer
for this service. This service is at
the discretion and expense of the
snowmobile owner.

1. Turn the engine off; then open the

left access panel.

2. Make sure the drive belt is posi-

tioned from 1.5 mm (0.06 in.) above

the edge of the driven clutch sheaves

to 0.5 mm (0.02 in.) below the edge.

SNO-337

3. Adjust the position by removing or

adding a spacer on each adjusting

bolt.

SNO-338

Spacer Part Numbers:
90201-061H1: 0.5 mm (0.02 in.)
90201-06037: 1.0 mm (0.04 in.)

4. Close the access panel.

DRIVE CLUTCH AND DRIVEN 
CLUTCH

Keeping the drive clutch and driven

clutch clean should be the primary con-

sideration of the operator. The drive

clutch and driven clutch can be cleaned

of any drive belt accumulation using

compressed air. The sheaves can be

cleaned using a clean cloth and parts-

cleaning solvent.

WARNING

If the belt is not positioned cor-
rectly, the clutch engagement speed
will be changed. The snowmobile
may move unexpectedly when the
engine is started. 

CAUTION

As the belt wears, adjustment may
be necessary. To ensure proper
clutch performance, the belt posi-
tion should be adjusted by adding a
spacer (2) on each adjusting bolt
(1) whenever the belt position
reaches 1.5 mm (0.05 in.) below the
edge of the sheaves.
