SmartCarbs are proudly made right here in the USA. Backed by nearly 60 years of American ingenuity, the SC3 distills the best of its predecessors into the ultimate mechanical fuel system. 📐🇺🇸

58 years ago, William “Red” Edmonston changed carburetion forever with the Lake Injector. In it began the technological journey that would culminate in the SmartCarb SC3.

But a blueprint is only the beginning. SmartCarb Fuel Systems’ founder, Corey Dyess, worked directly with Red and he has subsequently built upon those foundational principles, relentlessly refining them for the modern rider over the past two decades.

Every SmartCarb built is precision CNC-machined and assembled with care here in America’s Heartland by a team of technicians who refuse to settle for “good enough.”

Upgrade your ride with the best.

If dirt bikes weren’t meant to fall over they would have put a third wheel on them.

It just happens, and when it does, fuel spills out of the vent lines onto the ground, into the crank, down your pant leg, you get the idea.

Not so with the SmartCarb. This carburetor uses a patented, integrated venting system with check-valves designed to prevent flooding whether upright or when tipped over. Even upside down. No more fuel spillage no matter how much of a pickle you get yourself into.

Integrated venting with tip-over protection is just one more thing that sets the SmartCarb apart from the competition. Get equipped!

It’s one thing to copy our claims. Matching our tolerances is another story.

SmartCarbs are precision instruments designed, machined, and assembled with care right here in the USA. No cheap components, no dangly hoses, no compromises - just genuine American ingenuity and a product with nearly 60 years of development behind it.

Don’t be a squid.

Look at your carb. If it has more hoses than a Home Depot garden center you’ve got yourself a potential liability. They leak, they clog, and they can pull water in. When venting stops, so do you.

Now look at the SmartCarb. No external vent lines, no problems. SmartCarbs vent their float bowls right at the manifold, inside of the airboot. Not only is it a cleaner look, it makes the SmartCarb a sealed system with zero fuel spillage.

Ditch the brass. Keep the freedom. 🇺🇸💨

Every minute you spend fiddling with jets track or trailside is a minute you aren’t riding. What’s your time worth?

Designed, machined, and assembled right here in Raytown, Missouri, the SmartCarb delivers precise air/fuel mixtures using a single-circuit. It compensates automatically for elevation or temperature changes and if you do need to do some fine tuning, you do it entirely by hand, without tools, using the external clicker adjuster on top.

No jets to drop in the dirt, no sensors that fail, and no apps to download. Just pure, American-made performance that lets you focus on the ride, not the wrenching.
