Arlen Ness Big Shot II Adjustable Fuel Tuner - Harley Davidson V-Rod (08 - 11)

ZOOM

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 the only time adjustment is needed is when you modify your engine.
