Getting the Most out of your Fuel System with a Fuelpak

   When it comes time to install performance, an exhaust system is the first step to adding power to your ride. Now, you need a fuel management system that can handle the job and install with ease. You need a Fuelpak from Vance & Hines, available from your friends at K and G Cycles (

   Your fuel injected Amfuel pakerican V-Twin is equipped with an ECU (electronic control unit) that’s programmed to deliver fuel to the motor based on an air/fuel ratio for a stock air filter and stock Exhaust system. While the ECU can self-adjust for environmental factors such as temperature and altitude, it can’t adjust for mechanical changes like adding performance parts. When you install a performance Exhaust system, your airflow changes, so you need a fuel management system that adjusts your air/fuel ratio to match the changes. That fuel management system is The Fuelpak from Vance & Hines. The perfect combination with your performance Exhaust system. Ahead of the competition, The Fuelpak is the most advanced system of it’s type. Nothing will compare.

   Asfeul pak chart shown in the illustration, your stock air/fuel ratio runs just slightly lean, however, when you install an aftermarket Exhaust, that ratio changes, becoming even leaner. The white dashed line reflects the baseline air/fuel ratio and where you want to be for optimum throttle response. Unlike other fuel management systems that can only add fuel, The Fuelpak from Vance & Hines adds or takes away fuel, allowing for a more precise range of refinement in your air/fuel ratio. Designed and manufactured entirely in-house, the technical staff is constantly at work developing custom fuel maps for popular brands.

   Don’t settle for a system that is difficult to install. Afterall, you want to focus on what you enjoy most. Riding. When the engineering staff at Vance & Hines designed Fuelpak, the focus was on making installation and use as simple as possible. The Fuelpak from Vance & Hines plugs directly into the factory wiring harness and ECU using t-tap and OEM style connectors to stay fastened securely to your bike. Fuelpak fits so discreetly that, with the exception of the improved throttle response and rideability, you won’t even know it’s there. And should you ever remove Fuelpak, your motorcycle will return to operating at it’s original factory settings.

  No computers are needed, and there is no need to tune your bike on a dyno. All the hard work was done for you. Once the Fuelpak is installed, locate your fuel map from the setting chart provided or look it up here. Next, wth the ignition turned on, enter the values for your specific map directly into Fuelpak and calibrate your TPS (throttle position sensor). Finally, shut off the ignition, put the cover back on and you’re ready to ride. That’s the beauty of Vance & Hines Fuelpak,  the settings you entered are the result of our extensive dyno and road testing to find the ideal fuel map for your Harley.

   So call your friends at K and G Cycles ( and let them help you get your hands on one of the easiest tuners on the market for your Harley and experience the difference.
