THROTTLE BODY
1. Idle stop screw (do not tamper adjustment)
CAUTION:
It is not allowed to perform any
change on the idle stop screw.
The adjustment of the idle stop screw is optimized
by the throttle body manufacturer and locked to
prevent any modification.
CAUTION:
Never attempt to adjust the idle
speed through the throttle body tamper proof
screw. If so, it would impair the idle speed
stability.
Besides, no adjustment could be
performed by the dealer or the factory to cor-
rect the idle speed. The throttle body would
need to be replaced. Also take into account
that it might change the engine emission level
and the engine might not meet the EPA/CARB
requirements.
CAUTION:
Do not alter or tamper with throttle
cable adjustment or routing. It may cause poor
startability and erratic idling.
When the throttle body has been replaced, per-
form throttle cable adjustment (see below) and
then the
Closed Throttle and Idle Actuator reset
.
Refer to THROTTLE POSITION SENSOR (TPS) fur-
ther in this section.
Throttle Cable Adjustment
Mechanically adjust the throttle cable.
Lubricate cable with BOMBARDIER LUBE lubri-
cant.
When throttle is released, cable must have a free
play of 0.5 - 4 mm (1/64 - 5/32 in).
Besides, throttle lever must reach handlebar grip
without causing strain to cable or brackets. En-
sure throttle lever fully closes on it's stopper.

1. Must touch handlebar grip
Ensure throttle body is fully open at full throttle
position. At this position, throttle lever stopper is
almost in contact with throttle body.
NOTE:
Apply a light pressure on the throttle plate,
a slight play should be obtained.
CAUTION:
If there is no free-play at idle posi-
tion, it may cause poor idling and startability.
Improper cable adjustment will cause strain on
cable and/or damage cable bracket or throttle
lever at handlebar.
To adjust, loosen jam nut then turn adjustment nut
as necessary.
