Slavens Mule 38mm H-Series Lectron Power-Jet Carburetor for Beta
Slavens Racing has teamed up with Lectron Fuel Systems to produce the ultimate carburetor for the Beta 2 stroke models. Jeff is always looking for ways to improve performance, power delivery and fuel economy on all Beta models (old & new) so he asked for help from Kevin at Lectron. The combined teamwork has evolved into the H-Series carburetor. The 38mm H-Series Beta Lectron carburetor delivers the low-end and mid-range torque/grunt of a 36mm carburetor and the horsepower and top-end over-rev of a 38mm carburetor. The increased performance and smooth power delivery combined with a big increase in fuel mileage and automatic elevation/temperature compensation make it a no brainer. Once correctly set-up, the Beta Lectron carburetor is on auto-pilot.
The new slide works in conjunction with the increased bore taper to create more airflow (CFM) at low throttle positions. This generates higher velocity, more fuel lift, and a faster, torquier hit immediately off idle without being snappy or uncontrollable. The higher velocity also activates the power jet earlier to create a stronger, more tuneable mid-range.
Lectron’s dyno testing has shown a 20% increase in torque and horsepower at 5000RPM compared to the outgoing 38HV on a KTM 250. This is what riders refer to as “bottom end.” It is the meat of the powerband for off-road riding and creates faster acceleration out of corners for all disciplines. In layman’s terms, this carb straight barks. Rideability is improved with a lighter stock spring for reduced forearm fatigue. Shop Slavens Racing for all your Lectron Carburetor needs!
