INTRODUCTION
The S&S® Fuel System Upgrade Kit includes a VFI (Variable Fuel Injection) module, 52mm single bore throttle body kit, manifold, and Teardrop air
cleaner. These components replace the stock fuel injection system on 1995 to 2001 Magneti Marelli® style fuel injected touring motorcycles. The USB
Magneti Marelli Style VFI module works with all 1995 through 2001 touring EFI motorcycles and comes pre-programmed with a calibration for an
80” Harley-Davidson® Evolution® engine or 1550cc (95”) Twin Cam 88® depending on the kit that was ordered. Additional calibrations are available
on the included Pro Tune II software CD and from the S&S website.
