1.0 - GENERAL SAFETY PRECAUTIONS
This dry nitrous system is intended for
Fuel Injected Motorcycles Only!
It should only be installed by a competent technician
with nitrous experience. This is
FOR RACE USE ONLY
and is not intended for public roads or highways.
All wiring and nitrous lines should be wrapped with the provided wire loom and positioned in a way to prevent engine heat from
doing any damage. The use of electrical tape at the end of the wire loom adds to the effect of “stock appearing”. We also suggest running
all the wiring and nitrous line alongside stock wiring. Be sure all wire terminals are water tight to prevent corrosion. The water proof
arming switch should also be located in a discreet location to prevent detection.
The nitrous bottle should be mounted away from any engine heat. Under the seat is a good location.
The nitrous nozzle should mount in a ram air tube or at the very front of the air box. This is to assure that the Airbox Sensors
are hit with the nitrous oxide. The nitrous will pass through the air filter.
Start with the smallest supplied jet. Try it on the dyno first, then try it on the race track. Use stock ignition timing only when
you are using the nitrous.
Advancing the timing can cause engine damage.
Using a minumum 90 octane gasoline is highly
recommended.
Do not use the nitrous to increase the horsepower by more than 40. Doing so can/will cause piston or spark plug failure resulting
in severe engine damage.
If your fuel injected motorcycle is equipped with a Power Commander, it is recommended that you increase the high rpm
faceplate by two bars. This is to insure enough fuel will get to the engine. Refer to your Power Commander manual for instructions.
Do not allow the engine to hit the rev limiter while using the nitrous. An RPM activated switch may be installed to turn off the
nitrous before the rev limiter has been reached. Refer to wiring diagrams for more information.
Do not attempt to use the nitrous in first gear. Tire spinning or an uncontrolled wheelie may result.
IMPORTANT -
Always wear proper safety gear while racing your motorcycle. This includes a minumum Snell 95
helmet, leather jacket, leather gloves, boots that cover your ankles, and leather pants. Additional padding is
recommended.
