New Lectron H-Series:  https://www.youtube.com/watch?v=MrDoA25r5X4&t=1s New mold with 60% more aggressive venturi and redesigned bell. Improved slide design Earlier power jet activation Double the idle adjustment Lighter throttle pull Shorter overall carb length New black and yellow themed sticker The new slide works in conjunction with the increased bore taper to create more air flow (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 tunable 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
