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.

5.0 - POWER COMMANDER TUNING TIPS

When using the Nitrous System, more fuel may be needed to be delivered to the engine using the Power Commander. To do this, you can use the Power Commander Faceplate and richen the high RPM. Another way is to go into the Map Program and richen 100% throttle table to the desired amount. Refer to the Power Commander manual for further instructions. Use of a dyno is recommended for proper tuning.
