Description for Arlen Ness Big-Shot 2 C.A.R.B. Approved 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
