Slavens Mule 38mm H-Series Lectron Power-Jet Carburetor for pre-`17 KTM, Husqvarna, Husaberg
Slavens Racing has teamed up with Lectron Fuel Systems to produce the ultimate carburetor for the 2016 and earlier KTM/Husqvarna 2 stroke models. Jeff is always looking for ways to improve performance, power delivery and fuel economy on all KTM/HQV models (old & new) so he asked for help from Kevin at Lectron. The combined team work has evolved into the Slavens Racing Mule H-Series carburetor for 2016 and earlier models. 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 Lectron is on auto-pilot.
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 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 power band 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.

Message: Mr Slavens, I have just purchased one of these items and thought I needed to share my experience. You’ll be pleased to know, despite being a Kiwi (New Zealander) and tinkering is a natural habit, I resisted the urge after hilariously reading your instructions and gathering there was nothing to tinker with that could cause good things to happen. For those that are slow readers I’ll cut to the chase, the bloody thing is brilliant, does what it says on the box (even without tinkering?) and I’d highly recommend. But then I knew that because you have recommended it and so far….. Ring ominous bell….. you’ve not been wrong!! It took a mere 20mins to install and most of that was the new throttle cable. I adjusted, touched or fiddled with nothing, absolutely nothing not even idle and the bike started second kick (it is due for a new top end ) and idled perfectly. Today I gave the damn thing a good test ride with 4-5 hours of mostly tight and very technical stuff, but also including WOT sections and “Oh my god I am gonna die” rhythm sections at speed. I believe you promised me the same if not better low end and significantly more top end with this carb (being a 38 over a 36 standard, you’d sort of hope so). I might be over stating your warranty ), but no less it delivered, in my opinion, more bottom end and the top…. should come with a warning on the box, my right arm is held on with bolts and sticky tape (I’m sure that is what the surgeon called it) and it certainly felt like I needed to get some enforcement work done on that after today’s fast sections. Thank you, sir, for yet another great product, great fast (to the other side of the world) service and as always great grin factor. Although you have left me with a twitch as I resist the urge to fiddle), there is no way I will be wanting to mess up that sweet fueling. P.S. more than happy for you to use this anyway you feel fit. You and your team have earned it.
