Lectron HD-X Carburetor Kit for Harley Davidson & Similar | Powerful, Responsive, & No Jetting Simplicity (56ci - 124ci)

Yes, the HD-X is compatible with most OEM throttle assemblies. However, we do not recommend removing the cruise control stop from your throttle to achieve full pull. Doing so can cause excessive tension, leading to premature wear on the throttle cable and reduced overall lifespan. For best performance and durability, using the included throttle and cable that come with the HD-X kit is required.

Lectron carbs are built for riders who want simplicity without compromising performance.

Unlike stock carbs that rely on jets and constant tuning, Lectron uses a metering rod system that automatically adjusts fuel delivery based the conditions around you (elevation, temperature, humidity, etc..) . No jets to swap. No guessing. Just ride.

Here’s what sets us apart:

• No Jetting Required – Adapts to changes in altitude, temperature, and mods automatically.
• Smooth, Predictable Power – Strong bottom-end and midrange torque with linear throttle response.
• Fewer Parts, Less Tuning – Simpler design means less time wrenching and more time riding.
• Built for Performance – Whether you're racing or trail riding, you get better performance without the hassle.

It’s the performance you want, with the simplicity you’ve been missing.

We recommend using premium fuel with a minimum octane rating of 91 for all 4-stroke applications. Lower-quality or low-octane fuel can cause tuning issues, poor performance, and starting problems—not just with our carburetors, but with any carb system. For the best results, stick with fresh, high-quality fuel to ensure consistent combustion and optimal throttle response.

No problem - we've got you covered. Our dedicated support team has extensive experience tuning and installing Lectron carburetors across a wide range of bikes and riding styles. Whether you're working through your initial setup or fine-tuning for specific conditions, we're here to help. Reach out anytime - we'll make sure your carb is dialed in and your bike runs like it should.

We have over 50 years of experience with tuning carburetors. We setup each carb to a fundamentally determined setting based on information you provide to us. Your carb will be very close or spot on when received. With that said, varying factors like the bikes condition, wear, maintenance, oil ratio, and age of fuel can have an effect with tuning. We suggest a simple, slight tuning at install to achieve max performance and preferability. Once you set it, forget it. Enjoy no-hassle.
