Arlen Ness Big-Shot 2 Adjustable Fuel Tuner

• Improving upon the original Big-Shot, the Big-Shot 2 now gives the user the ability to add or subtract fuel from the fuel injection system

• Using the same load based technology as the original Big-Shot, the Big-Shot 2 always knows how much fuel your bike needs whether you’re going uphill, downhill, cruising or even towing a trailer

• Even temperature and elevation do not affect the Big-Shot 2; essentially, the only time adjustment is needed, is when you modify your engine

• Plug-and-play system and does not require the use of a computer or Dyno machine to get your bike running great

• C.A.R.B. approved systems are also available for customers living in California

If you are mechanicley inclined you can do this.Read the instructions.Do this till you understand them.When installed the functions work when the bike is running.The Big Shot 2 did take care of my modification problems ,from my new exhaust and intake.
