Just imagine another 20 to 40 horsepower in just 2 hours! That’s the reality of our Dry Nitrous Kit For Fuel Injected Motorcycles. Flip the switch to activate the nitrous and turn your starter button into a horsepower button. Our kit comes complete with all wiring. The MPS Dry Nitrous Kit was designed to easily increase horsepower of a four cylinder fuel injected motorcycle. These Dry Nitrous Kits exploit the ability to add fuel and yield between 20 and 40
horsepower. They are strictly for fuel injected motorcycles. The MPS Dry Nitrous Kit For Fuel Injected Motorcycles is for use in closed course competition events only and are not for use on any public street or highway.
Please note: The Dual Nozzle kit does not contain any jets. The standard Dry Kit comes with 28,32 and 36 jets. We can substitute jets as needed. Just let us know. The Dual Nozzle kit includes a flat nozzle mount.

Danger: Nitrous bottles can explode. Never exceed 1000 lbs of bottle pressure. Nitrous pressures over 1000 lbs or so can prevent the nitrous solenoid from opening. Do not expose the bottle to direct sunlight or leave the bottle enclosed in a container in direct sunlight. If you mount your bottle in your trunk or under the seat be sure to take the bottle out before letting the bike sit in the sun. Nitrous gains pressure with temperature. Do not mount the bottle near any source of heat. You will need to find a place that the bottle is out of sight, away from heat, secure, and accessible. Above the motor, under the tank is not a good spot in other words! To heat your bottle, use a bottle warmer, not a torch!
Fuel Injected Horsepower


That's right...........an incredible 216.5 horsepower from a stock Hayabusa! Our customer came in and bought our Dry Nitrous Kit and a Fast FI Mixture Control for his Hayabusa. Went home and installed them both. A couple days later he wanted some help with jetting so off we went to the dyno. We made the first pull with all stock settings in the Fast FI Mixture Control and no nitrous. That baseline pull netted an average 155.9 horsepower. The next pull we sprayed it with a 36 nitrous jet using the instant rich feature on the Fast FI Mixture Control. That pull was good for 194.1 horsepower and the sniffer indicated its still pretty rich. This is really good news because we can get almost 40 horsepower from a really rich mixture providing an extra measure of safety from hurt parts. We made the next pull with a 43 nitrous jet. It made 216.5 and was still rich. We stopped there even though there was more left obviously.
