Remove the throttle stop screw from the throttle
control on top of the engine. Place a couple of
drops of red thread locker on the front third of the
screw. Reinstall the throttle stop screw; it should be
turned in about a third of the way.
NOTE:
Before adjusting the speed, make sure
that the rear wheels are o
ff
of the ground and
secure the chassis so the engine can be started and
accelerated to full speed.
Re-adjust the throttle cable so that there is a small
amount of free-play where the cable connects to
the pedal. Tighten the throttle cable lock nuts. Re-
check that the desired RPM/speed has not changed.
Reinstall the air cleaner on the engine.

With a J&J Vortex gauge or a tachometer (where you
can see it), rev the engine up to full throttle. Adjust
the throttle stop screw until the engine is set at the
desired speed or RPM ( J&J recommends 17mph or
3650rpm). See page 6-29 for gearing & speed setup.
NOTE:
Rookie karts (Talon & Stinger) are set
to 3300 rpm at the factory. This translates to
approximately 12mph.
