38mm SC2

This 38mm SC2 model SmartCarb is designed to replace conventional, spigot mounted carburetors in 250-500cc 2-stroke applications, offering unbeatable performance and incredible ease of use. It is a direct fit in applications originally equipped with Keihin PE, PJ, PWK and Mikuni VM and TM series carburetors of similar size.

The SC2 SmartCarb is a precision metering instrument that provides extremely fine fuel atomization, precise mixture control, and air density compensation in a single circuit, jet-less fuel system.

• CNC billet aluminum construction
• Patented single fuel circuit design
• Extremely fine fuel atomization
• Optimal air/fuel ratio control
• Designed & manufactured in the USA

The SC2’s patented variable venturi shape focuses airflow directly at the metering rod, maximizing fuel atomization and combustion efficiency at all throttle positions.

• 8-10% increase in horsepower & torque
• 25-30% greater average fuel economy
• 30-50% reduction in emissions outputs (2X EPA certified)
• Crisp, clean throttle response & substantial top end overrev
• No compromises

The SC2 SmartCarb is externally adjustable track or trail-side in seconds. Patented, internal float bowl venting provides unmatched air density compensation.

• Tool-free, external adjustability – in seconds!
• Automatic air density compensation (elevation, temperature, even boost)
• NO jets & NO more jetting
• Integrated venting system – no dangling vent lines
• Zero fuel spillage
