THROTTLE AND CHOKE CABLE 
ADJUSTMENTS

Idle Speed Gap / Throttle Free Play 

Adjustment - VM Carburetors

1.

Always set the idle speed when the engine is at
operating temperature.

2.

Turn the idle speed adjustment screws on each
carburetor out at least 2 turns.

3.

Reference the throttle gap drill bit size specification for
each engine. Insert the drill bit(s) under each of the
throttle slide cutaway(s).

4.

Loosen lock nut(s) (on top of carburetor) and turn the
throttle cable adjuster in (clockwise) or out
(counterclockwise) until a slight drag can be felt on the
drill bit.

5.

Secure the adjuster lock nut(s).

6.

Slowly turn each idle speed screw inward until the tip
begins to touch the throttle slide. Remove the drill
bit(s).

7.

Set the throttle lever free play by loosening both
carburetor adjuster lock nuts. Turn each adjuster out
equally until the throttle lever free play is set.

8.

Secure the adjuster lock nuts.

NOTE:  If the idle speed screw is adjusted inward and
the cable sleeve is not adjusted to take up the throttle
lever clearance, the engine may misfire or quit upon
initial throttle opening.

CAUTION

When adjusting throttle lever free play, always verify the
engine idle RPM does not increase when turning the
handle bar to the full-left or full-right positions.

After idle speed adjustments are made, the throttle lever
clearance and oil pump adjustment must be checked
and adjusted.

Throttle Lever Free Play - TM Carburetor

Throttle lever free play must always be at a specified
clearance (A) .010

-.030

 (0.25-0.80 mm) between the

throttle lever (B) and the throttle block (C). This clearance
is controlled by the throttle cable (D).

If adjustment is needed follow these steps: 

1.

Check the idle RPM and verify it is within the specified
range.

2.

Shut off engine.

3.

Locate the throttle cable that is attached to the
carburetors and adjust the throttle free play by
adjusting the barrel nut (E) and lock nuts (F).

4.

Once the proper free play of  .010

-.030

 (.25-.80mm)

is set, tighten the lock nuts.

5.

Verify the oil pump index marks are within
specification.

6.

Check the idle RPM and verify it is within the specified
range.

NOTE:  If the idle speed screw is adjusted inward and
the cable sleeve is not adjusted to take up the throttle
lever clearance, the engine may misfire or kill upon
initial throttle opening.

Choke Lever Adjustment - Mikuni VM

1.

Flip the choke toggle to the “OFF” position.

2.

Loosen choke cable lock nut(s).

3.

Turn cable sleeve adjuster counterclockwise on the
carburetor until choke toggle has zero free play, then
rotate it clockwise until 1/8" to 1/4" (.3 - .6) toggle free
play is evident.

NOTE:  Verify the plunger does not lift when checking
the free play.

4.

Tighten adjustment lock nut.

5.

Repeat steps on the other carburetor.

In. / mm. 

Throttle Lever Free Play: .010"-.030" (0.25-0.8mm)

CAUTION

When adjusting throttle lever free-play, always verify the 

engine RPM does not rise with bars in the full low and 

full up-right Rider Select positions (if applicable) and 

while turning the handlebars to the full left and full right 

positions.

CAUTION

After any idle speed adjustments are made, the throttle 

lever clearance and the oil pump adjustment must be 

checked and adjusted.

Flip the choke toggle to the “OFF” position.

2.

Loosen locknuts (1) on the carburetor.

3.

Turn sleeve adjusting nut (2) counter-clockwise until
the choke toggle shows no free play when pulled, then
rotate it clockwise until there is between 1/8 - 1/4in
(3.2-.6.4mm) free play (3).

NOTE: Verify the cable does not lift the plungers
when checking the free play.

4.

Tighten adjustment locknut (2).

Handlebars

Periodically inspect the torque of the handlebar clamp
fasteners.

1.

To adjust the handlebar angle, remove the handlebar
cover to expose the clamp.

2.

Loosen the four clamp fasteners. Slightly pry the
upper clamp up with a flat blade screwdriver.

3.

Adjust handlebars to desired position. Verify the
wiring harness, brake hose, and throttle cable do not
kink.

4.

Secure the front clamp fasteners first to 11 - 13 ft.lbs.
(15 - 18 Nm). Finish by securing the two rear clamp
fasteners to the same torque setting.

5.

Reinstall the handlebar cover.

Ski/Skag Fasteners

Periodicaly inspect the ski-to-spindle fasteners for proper
torque.

Inspect ski skags and skag fasteners for abnormal wear
and tear. Replace skags when carbide edge is worn away.

Always use new Nylock nuts and secure hand tight.

Track Tension

Track tension is critical for maintaining correct suspension
operation. If the track tension is too loose it may cause the
track to slip or “ratchet”. If the track is too tight it will wear
down the rail slides, reduce top speeds, cause rear
suspension vibration and cause track and rear suspension
durability problems.

1.

Lift the rear of the machine and place a jack stand or
secure the rear of the machine so that the track is off
of the ground.

2.

Start the engine and slowly let the engine turn the
track over. This will warm up the track for a correct
measurement.

3.

Shut off the engine.

4.

Place a 10 lb. (4.54kg) weight at point (A). Point (A)
is 16” (41cm) ahead of the rear idler shaft (E).

5.

Measure the distance (D) between the rail slider and
the track. This measurement should fall with in the
measurement range for the appropriate vehicle, see
chart on this page.

6.

If adjustment is needed, loosen up the lock nuts (B)
on each side.

7.

Loosen up the idler shaft bolts (F).

8.

Turn each adjuster bolt (C) clockwise to tighten track.
Turn the adjuster bolt counterclockwise to loosen
track tension.

9.

Torque the lock nuts (B) and idler shaft bolts on each
side to 35 ft-lb (48 N-m).
