DYNOJET Thunderslide Jet Kit - Harley-Davidson 1200 8109

If you're running a stock or modified 1200cc Harley with a CV carburetor, throttle response and fuel delivery are often the first limitations you'll hit. The DYNOJET Thunderslide Jet Kit addresses this directly by optimizing how your slide opens relative to throttle input, delivering measurable gains in both power and fuel efficiency. This is a bolt-on solution that works with your existing setup—no fabrication required.

The lift-hole design on the composite plastic slide controls the rate at which the needle rises, effectively tuning your carburetor's response curve. A faster slide opening means quicker throttle response and better fuel atomization across the RPM range. Whether you're running stock or aftermarket air and exhaust, this kit is engineered to complement your current configuration without requiring a complete carb rebuild.
