Section 04 ENGINE MANAGEMENT (SDI)
Subsection 03 (COMPONENT INSPECTION, REPLACEMENT AND ADJUSTMENT)
Before installation, clean throttle plates and bores
with pulley flange cleaner (P/N 413 711 809).
NOTE: The throttle body is designed as a single
part for both cylinders. No synchronization is re-
quired as it has already been done at the factory.
However, proceed with throttle cable and closed
TPS adjustments as described below.

THROTTLE BODY
1. Zero position stopper screw
CAUTION: It is not allowed to perform any
change on the zero position stopper screw.
The adjustment of the zero position stopper screw
is optimized by the throttle body manufacturer and
locked to prevent any modification.
CAUTION: Never attempt to adjust the zero po-
sition stopper screw (the capped one) or the
idle speed adjustment would be impaired. Be-
sides, no adjustment could be performed by
the dealer nor the factory to correct the zero po-
sition stopper screw. The throttle body would
need to be replaced.

TYPICAL
1. Idle speed screw
2. Zero position stopper screw
CAUTION: Do not alter or tamper with throttle
cable adjustment or routing. It may cause poor
startability and erratic idling.
The only screw that has to be adjusted is the idle
speed screw and it has to be adjusted only with
the closed throttle reset procedure or for high al-
titude application. This has to be done only if the
ECM or throttle body are replaced or if screw has
been tampered with by mistake. Refer to THROT-
TLE POSITION SENSOR (TPS) in this section.
Throttle Cable Adjustment
Handlebar and throttle cable must be at their nor-
mal position.
Adjust top nut to have a small cable free-play at
idle position.
