8731 Thunderslide CV kit, US models. Stage 7

This Dynojet Thunderslide US Stage 7 kit is designed for 2000 to 2006 Twin Cam models that need a more aggressive fuel calibration. The Thunderslide's unique throttle slide profile allows for incredibly precise control over the slide's movement, which creates a stronger signal for better fuel atomization. This leads to a more efficient fuel burn, providing more power and much sharper throttle response than a standard jet kit. It is also designed to improve fuel economy during normal cruising. Sold as a kit, this Stage 7 setup is the ultimate tuning solution for riders looking to push their Twin Cam's CV carburetor to its performance limits.
