Boondocker Nitrous Kits

The Boondocker Nitrous System uses a patent pending nitrous manifold that injects nitrous before the carburetor into the air intake and at the same time pressurizing the carburetors to increase the amount of fuel being vaporized. This results in an effective horsepower increase because the amount of nitrous being injected is matched by additional fuel. A push button switch located on the handlebars activates the nitrous - 15 or 20 shots available. The amount of nitrous being injected can be adjusted on the manifold so it can be set up for different applications and riding types.

  • Dry shot Nitrous system uses carburetor pressure to adjust fuel automatically as needed and is totally adjustable for your personal application.
  • Nitrous manifold automatically adjusts fuel for variances in bottle temperature
  • Solenoids run off of the stock electrical system so no battery is needed
  • New Polished bottles available
  • Easy to adjust by turning a screw on the Nitrous manifold
  • Kits come with brackets custom designed for each application
  • EFI kits available!

We are a NOS refill station too!
