8730 Thunderslide CV kit, US models. Stage 7

For those looking for maximum performance on a 1999 Twin Cam, this Dynojet Thunderslide US Stage 7 kit is the answer. The Thunderslide design uses a custom-profiled throttle slide to precisely manage movement and create a stronger vacuum signal. This superior atomization of fuel is essential for high-performance tuning, providing a significant boost in throttle response and power delivery. It also helps with fuel efficiency by ensuring a more complete burn. This is sold as a kit and is intended for US models that require the more aggressive Stage 7 calibration. It is a top-tier choice for riders who demand the most from their Keihin CV carburetor.
