ARCTIC POWER VALVE
(APV) SYSTEM
This RPM controlled servomotor
(servo) actuated system adjusts the
size of the exhaust ports to provide
peak performance throughout the
RPM range. The system consists of
an exhaust valve assembly mounted
to the exhaust side of each cylinder
and connected by adjustable cables
to an electronic servo mounted
beneath the hood.
NOTE: The mounting location of
the servo will vary from model to
model.

At low RPM, the exhaust valves are
held in the DOWN position by
return springs. This gives the engine
a “low port” exhaust design cali-
brated to provide maximum low
RPM power and improve fuel econ-
omy at trail speeds.
