DYNOJET Stage-7 Thunderslide Jet Kit - Harley Davidson 8708

If you're running an 80+ horsepower engine and want throttle response that matches your bike's power output, a proper fuel delivery tune is non-negotiable. The DYNOJET Stage-7 Thunderslide Jet Kit optimizes your carburetor's air-fuel ratio across the entire throttle range, delivering noticeable gains in both horsepower and fuel efficiency. This is a bolt-on solution that eliminates hesitation and gives you the crisp, linear response your engine deserves.

The Thunderslide design uses precision-engineered lift holes that control slide opening speed relative to throttle position—faster slide movement means quicker response without sacrificing drivability. Unlike generic tuning approaches, this kit accounts for the specific demands of larger-displacement Harley engines, ensuring consistent performance whether you're cruising or pushing hard.
