The Nikko Racing Injection Adjuster can change the stock fuelling map to allow for after-market exhausts, air filters etc.
A standard workshop tool allowing a fast adjustment without any installation worries.
Similar to the Yoshimura Fuel Injection Adjuster Box but more economical.

Compatible with almost all Suzuki fuel-injection bikes including the GSX-R600 (2001-08), SV 650 (2003-08), DL 650 V-Strom (2004-08), GSX-R750 (1998-1999), GSX-R750 (2000-08), GSX-R1000 (2001-08), SV 1000 (2003-07), TL 1000S (1997-01), TL 1000R (1998-03), DL 1000 V-Strom (2002-07), GSX-R 1300 Hayabusa (1999-08), GSX 1400 (2001-07).


The injection adjuster plugs directly into the diagnostic connector and can work with both 16 and 32-bit processors.

It has two modes of operation:
A - For idling and low revs: can ajusts the fuelling mixture +/-8% on individual cylinders.
B - For three throttle position ranges (0-40%/40-80%/80-100%): can adjust the fuelling -10%/+15%.

Simple to use and nothing to install on the bike itself.

Operating Instructions

To achieve perfect fuelling and precise modification of the fuelling map, we recommend the Healtech FI Tuner Pro (installed on the bike itself).
