PART 1 of 2 -- Installation -- The SmartCarb 2 (SC2) from Technology Elevated is the ultimate two stroke dirt bike carburetor for jetless fuel delivery. Similar to the Lectron, the SmartCarb uses metering rod technology and a sealed/pressurized float bowl to compensate fuel delivery for varying air densities and barometric pressures. Basically it's almost like fuel injection in practice, but a lot simpler in design. From what we can tell, the SmartCarb's proprietary venturi and sealed system make it a superior design to the Lectron, especially for single track riding. It's almost impossible to stall this bike now (GYTR flywheel weight helped too), the off idle response is incredible. It's perfect for these rocky/rooty Colorado hill climbs and technical single track. The bike's top end woke up more too (as compared to the Keihin with FMF Gnarly and JD Jetting Kit) with substantially more over-rev.
Take a look at this video to get a full understanding of the installation process on a 2019 Yamaha YZ 250X (same for YZ250 minus the reed valve spacer) and what to be aware of that is specific to the Smart Carb. Check out video 2 to go for a ride and have a full review of the carb after about 15 hours of riding.
