8733 Thunderslide CV kit, US models. Stage 7

Designed for 1999 to 2017 Twin Cam models running a 44mm Keihin CV carburetor, this Dynojet Thunderslide US Stage 7 kit provides professional-level fuel tuning. The Thunderslide replaces the stock slide with a custom-profiled version that allows for much more precise movement. This creates a stronger vacuum signal, atomizing the fuel more thoroughly for a more powerful and efficient burn. You will experience a noticeable increase in throttle response and overall power, along with better fuel economy. This is sold as a kit and is the ideal choice for high-performance Twin Cam builds that require the aggressive calibration of a Stage 7 kit.
