10.
All NX systems are designed to operate at 1050 PSI bottle pressure. This is extremely important and cannot
be stressed enough!!! If the pressure is below this, the system will be rich, if it is above this it will be lean!
The bottle pressure can be monitored easily with our bottle pressure
gauge (PN 15509P). In cool weather a
bottle heater is required (PN 15938P for 2.0lb or 2.5lb bottles or PN 15936P for 1.0-1.4lb bottles). The use
of an insulated bottle jacket will allow the heater to work more efficiently and will also stabilize bottle
pressure. In extremely hot weather a wet towel or chamois may be placed over the bottle to reduce
pressure.
11. A purge valve (PN 15600P or 15603P) is a must on all competition systems and a plus on the street
systems, as well. A purge valve is worth about a tenth of a second on a 1/4 mile pass. The correct purging
procedures for drag racing is listed here:
A. Complete your burnout.
B. Light the pre-stage bulb.
C. Push the purge button three times, in one second increments.
D. Stage immediately, go fast!!!
12. If traction is a problem a progressive controller (PN15957P or PN15835P) may be used to reduce tire spin
off the line, smoothly increasing power as the vehicle accelerates, eliminating ET robbing traction loss.
13. If there is a question about the purity of your nitrous supply, a filter (PN 15607P) should be used when
refilling your nitrous bottle. Contaminated nitrous will cause serious damage to your system components.
14. Periodically check all fittings, connections, and mounting bolts for leaks and tightness.
15. Always turn the nitrous bottle off when not in use, even between runs.
16. Always start with the lowest power setting in your system. Start out small and work your way up, NX
systems produce more “REAL” horsepower than any other on the market today!
17. If you run a 35+ HP system it is recommended that you run the highest motor octane racing fuel available.
Here are some tips to help you choose fuel for your bike:
A. The relevant number to look at when choosing a racing fuel is the “MOTOR” octane number or MON,
the research octane number is not a reliable gauge of fuel octane level.
B. Never store your fuel in a vented container; never store your fuel in white fuel jugs, or in direct sunlight.
If you must use plastic, use only dark colors. Sunlight will oxidize the lead out of racing fuel. Lead is
what makes it high octane. A steel “JERRY” can is the best.
C. Do not leave your racing fuel stored in the motorcycle tank. Keep it in a sealed, airtight container off the
floor.
D. NEVER USE AVIATION GAS!!!!!
Instant engine damage will be the result! The specific gravity of avgas is very light and it is not
formulated to operate in non-aircraft engines.
E. Never buy racing fuel from a vented container, or from an underground tank. Buy from a sealed drum
only.
IN CONCLUSION
This instruction sheet and power tuning tips are valid for NX systems only. If you have a kit from another
manufacturer this information will not help you. The instruction sheet from another manufacturer’s kit will not help
you with the NX system! If you need help call your dealer or the factory tech line.
DO NOT MIX ANY COMPONENTS FROM ANY OTHER MANUFACTURER, THIS WILL VOID ALL
WARRANTIES!!!!!
If you follow the foregoing suggestions, your NX system will operate trouble free. Got a problem? Call the factory
tech line 9AM to 5PM PST 877-648-7687.
