Vance And Hines 61003a

  • Item weight – 1.1 pounds
  • Best milage provider

Pros
  • Easy to install
  • Provides best air/fuel ratio
Cons
  •  It does not blend with the motorcycle design

Your fuel injected bike 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 Fuelpak.

The fuel pack plugs directly into the factory wiring harness and ECU using a t-tap and OEM style connectors to stay fastened securely to your bike. The Vance and Hines Fuelpak is easy to install and simple to use.
