For US models. Stage 1 kit. Used with stock CV carburetors unless specified otherwise. The Thunderslide for Harley-Davidson and Buell sets the new benchmark in jet kit design. It incorporates a custom made throttle slide. The unique configuration allows precise control over the slide’s range of movement. It creates a stronger signal, improving fuel atomizing which is essential for a good fuel burn. This provides more power, increased throttle response and improved fuel economy. **Dynojet product not available to purchase by Dealers located in the UK**
