Want to increase the fuel mixture for that new Exhaust or want to fit DNA stage 1 & 2 filters & worried about running your XT660 to lean, then this is the fuelling device for you. It is very easy to fit; you only cut one wire & join the two ends to the fuel controller via a quick connector supplied with the mod. This fuel mod is designed to run with your O2 sensor connected. I also supply full instructions via download with the XT660 workshop & parts manuals. So if you can’t afford a Power Commander then this mod is for you. This fuel mod fits XTX XTR & XTZ all models & all years.

How it works:

How it works: This fuel mod adjusts the Air temperature reading down from the actual ambient temperature. By adjust the temperature reading down the Engine Control Unit (ECU) thinks it is colder than it really is, so in turn makes the mixture slightly richer.
