ELECTRICAL
Electronic Throttle Control (ETC)
Always check the throttle pedal for smooth operation before
riding. Periodically check the throttle free play. It should be kept
between 1/16” and 1/8” (1.5mm – 3.2mm).
If adjustment is required, turn the throttle cable adjuster until the
free play falls within the acceptable limit.
ETC Operation
When the throttle is closed (idle), the throttle pedal arm
depresses a small micro switch that limits engine rpm. This
action opens the circuit.
When the throttle pedal is pushed forward, the throttle arm
moves off the micro switch and allows the engine rpm to
increase with lever movement. This action closes the circuit.
If the throttle cable would become hung up or stuck while the
vehicle is being operated, the spring loaded throttle arm will
return back and depress the micro switch, limiting engine rpm.
The ETC switch and throttle arm are located in a sealed throttle
pedal assembly. Switch or throttle cable replacement requires
removing the assembly cover. Always replace the cover gasket
with a new one during assembly.
ETC Switch Adjustment
1. Slide the boot off the throttle cable adjuster and jam nut.
2. Set parking brake.
3. Start engine and set idle to specified RPM.
NOTE: Be sure the engine is at operating
temperature. See “Idle Speed Adjustment” in
Chapter 2.
4. Loosen the adjustment nut on in–line cable adjuster.
5. Turn cable adjuster out until engine RPM begins to
increase.
6. Turn cable adjuster back in until throttle lever has 1/16”
(.16 cm) of travel before engine RPM increases.
7. Tighten lock nut securely and slide boot completely in
place to ensure a water–tight seal.
NOTE: Verify ETC switch plunger is held inward at
idle position.
