TIMING INFORMATION
The PRO X 440 has been equipped with two switches that will change the timing curve.
The first switch is an ignition switch located on the console.
This switch is used to match the timing curve to the type of
fuel you are using. The fuel types are92 octane non-ethanol
premium fuel and 110 octane fuel. Do not run the machinein
the wrong ingnition key position or engine damage will oc-
cur.
The second switch is located on the airbox and has seven optional curves. These seven options are used to match the fuel
type and the racing conditions which may vary, depending on the race. The standard position is “D” and should not be moved
unless you are a knowledgeable engine tuner.

The exhaust system has a temperature sensor in the body of the pipe that effects the timing curve as the temperature
changes. This feature helps the pipe tune quickly and is not adjustable.
This engine is jettedfor operationat 0 degrees and warmer. Re-jettingis required fortemperatures colder than 0_ F.
CAUTION
CAUTION

lector switch can cause
