If you are installing a new exhaust , un-plug and remove the EXUP servo motor from the bike. remove the plastic cover , then disconnect and remove the cables. Re-install the servo motor and plug back in to the harness.

This photo shows where to mount the TFI box on the new FZ1.

Piggy back each TFI plug into the injector plug on the throttle bodies then connect the bikes harness plug to the corresponding TFI plug as shown. Note! Be sure all connections are fully seated and clipped into place.

Neatly bundle up extra TFI harness wire and nylon tie as shown.

Connect TFI ground wire directly to the negative battery terminal.

Be sure to disconnect the 02 sensor plug as shown , also internally plug the hose from the bottom of the air box leading to the AIS smog valve. This can be done with a solid cork shaped rubber plug. You can also cap off the nipple in the air box leading to the hose and achieve the same results, but if you do also be sure to nylon tie as well. This step helps eliminate most decel popping when a exhaust is added.

Using a 1" hole saw carefully drill the air box as shown, be sure to de-burr and use a vacuum to clean things up when finished. Also only run the original stock air filter in new or very good condition with this set up.

You can email Dale or call him with any questions you may have or to get your TFI base settings, once you have made your purchase.
