DYNOJET Jet Kit - Harley-Davidson 883/12/1340 8105

If you're running a stock Keihin CV carburetor on your Harley-Davidson 883, 1200, or 1340, you're leaving performance on the table. The DYNOJET Jet Kit recalibrates your carb's jetting and needle positions to unlock the full potential of your engine, delivering measurable power gains across the RPM range while maintaining the smooth, predictable throttle response you expect from a street-tuned machine. This is the proven way to transform a stock carb into a performance asset without a complete fuel system overhaul.

Installation is straightforward—no fabrication required, just carb removal, internal recalibration, and reassembly. You'll notice improved mid-range response and top-end pull, especially if your bike has been modified with intake or exhaust work that's starved the factory jetting of proper fuel delivery.
