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