How to Modify a Suzuki Hayabusa 1300

The Suzuki GSX-1300R Hayabusa is one of the world's fastest and most powerful motorcycles. The 1300cc engine is fuel injected and controlled by a central computer. Fuel and air mixtures are set at the factory to give high performance while meeting a broad range of emissions requirements. A popular upgrade to the Hayabusa is the installation of a Power Commander module. The PCIII unit is the latest model of Power Commander and can be installed in minutes. It can improve mileage, horsepower, throttle response or change the horsepower and torque curves.

Things You'll Need

  • 5mm Allen wrench
  • Brake cleaner
  • Shop rag
  • Remove the rear cowl using the ignition key. Use the 5mm Allen key to remove the two bolts securing the seat to the frame. When the bolts are out, lift up at the back and remove the seat.

  • Remove the prop fuel tank prop rod from the rear storage area. Lift the back of the fuel tank and support it with the prop rod.

  • Unplug the fuel injector wiring harness connector. This is a white connector that has wires coming from the fuel rail and connects to the main wiring harness.

  • Locate a spot in the rear storage area to mount the Power Commander unit. Clean the spot using brake cleaner and a rag. Mount the Power Commander unit to the spot using the Velcro tape supplied with the Power Commander.

  • Route Power Commander's wires along the frame rails towards the front of the bike. The wires from the Power Commander have two connectors. Plug each connector from the Power Commander to the white connector you unplugged in Step 3. The connectors will only plug into each other one way.

  • Lower the fuel tank and reinstall the seat. Start the engine and follow the procedures for programming the Power Commander according to the instructions in the manual.
