Throttle Release Switch (TRS)

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.

TRS 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.
Micro Switch
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 TRS 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.
