Arlen Ness Big-Shot II Adjustable Fuel Injection Tuner for 2002-2008 Honda VTX1800


Not legal for sale or use in California due to federal anti-tampering laws.


Improving upon the original Big Shot, the Big Shot II 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 II 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 II; essentially only time adjustment is needed is when you modify your engine. The Big Shot II is a plug and play system and does not require the use of a computer or dyno machine to get your bike running great.

  • Pull up to 10% of fuel out of the system

  • 16 positions of adjustability

  • Adjustable to your riding style

  • Ability to tell the system how much fuel to add and when
