The SmartCarb is the culmination of more than 45 years of development of the single-circuit, flat-slide carburetor by renowned carburetor expert and inventor William H. Edmonston. Its pedigree comes from the long line of Edmonston-designed carburetors, including the Lake Injector, Pos-a-Fuel, Ei Blue Magnum, Quicksilver, and Lectron. The SmartCarb combines the best features from earlier flat-slide, variable-venturi carburetor designs and incorporates design features developed by Technology Elevated, making it a real world solution to satisfying emissions regulations and OEM performance requirements in small engine applications worldwide. Technology Elevated is currently focused on the off-road 2-stroke and 4-stroke powersports market, offering 25, 28, 36, 38, and 40mm SmartCarb sizes. Application driven development is underway, most recently involving testing for integration in UAVs, mini-motocross bikes, alcohol junior dragsters, micro-sprint carts, snowmobiles, paragliders, and outboard marine engines. The SmartCarb has proven itself to be viable in leisure and competitive applications and is capable of competing directly with electronic fuel injection for both passing emissions regulations and meeting performance requirements.

Taught me everything I had to know when it came to bikes, learned the clutch, the throttle, turns, jumps, and top ends! Got me off an old quad and taught me what real adrenaline was. It's been fun af to ride with tons of powa and speed but it's always braking down 😅 Highschool being boring af, this bike gets me away from that chore and gives me a chance to mess around once in a while. As old as it is, it's still a great machine.

The 2004 KX250 has a lot of 1 year only parts, so beware. This is now a street legal supermoto. A lot of parts are custom, including the wiring.

SC2 SmartCarbs are available in 36, 38, and 40mm sizes and are designed to replace conventional carburetors in 2-stroke applications from 125cc up to 500cc or more. They are a direct fit in applications originally equipped with Keihin PE, PJ, PWK and Mikuni VM and TM series carburetors of similar sizes. 38mm size depicted.
