The best upgrade you can get for your carbureted dirtbike! Makes tuning an ease and allows for a one and done setup. The best part is that the power delivery is felt stronger everywhere throughout the powerband.

Cable Adjusters | Legacy & H-Series Carburetors (2x Pack)
I am very happy with the ride quality and power delivery. I had to adjust the needle 1/4 turn leaner but other than that it was easy to install and get going. The videos out there are great to watch before you install as well.

First impressions even before tuning the carb I noticed instantly that the bike started up way faster than ever before. And with the stock carburetor Id have to pull the choke and or prime kick it a few times. With the Lectron carb I go and turn my key on and the bike starts within a second or two of touching the e-start. And throttle response was crazy good before tuning as well. No more randomly stalling or cutting out when it was semi cold and doing an almost WOT acceleration. Then after tuning it with the a few email interchanges between Tommy and I Tommy was able to tell me exactly what it needed in order to run cherry. I've never ran or ride a bike with a Lectron carb but after getting a few bugs out the way and can firmly say I 110% percent stand behind these guys and will always use their products and support their products. The bike runs absolutely incredible and honestly forget sometimes that it's not fuel injected cause it runs insanely good. Best thing I've done to my Ktm and plan to do it to my yz125 as well. And I can't thank Tommy enough for all the help and the 15 plus emails that were sent, Tommy's an awesome dude and really appreciate him.

Outstanding Performance
I bought the 38 Mil Lectron carburetor for my 1986 250R with only a pipe on it. This carburetor really released the true potential on my 250 with its great performance and throttle response. The throttle cable is a tad bit long but thats absolutely fine as it leaves play in the thumb throttle. Super smooth throttle response and cable. This carburetor and how it performs will turn your machine into a whole different kind of animal. I love the tuning on this thing too. Also not having to change jets for different elevations is nice. Never going back to any other carb I definitely recommend!

H-Series EVO Carburetor for 2-Stroke | Performance + Simplicity (38mm)
1 day to install and tune, i'm good to go
i have an older 2001 DRZ 400 with a large aftermarket fuel tank and a yoshimura exhaust, with the air box opened up for fun, elevation doesn't affect 4-strokes as much but when i i can go from 100' to 4000' in a day of riding its something to considerinstallation was very easy considering that its smaller than a flat side pumper carb, and the bike ran right away, it was a little rich at the start but like any new carburetor it needed to be tuned to my bike and thats where the big difference for me was.the process of tuning my old carburetor took about 2-3 hours to make a change depending on how much of a struggle the intake boot would be, i would have to take off the seat and fuel tank, part of my luggage rack, and exhaust brackets ao i could move the sub-frame te get enough room to get the old carb out of the bike and get the the jets in the float bowl (to spare you the details i couldn't simply rotate my old carb to get access, it HAD to come off), and that was for every adjustment, the old carb was too close to the starter to even get to the air mix screw, it was not fun.now onto the Lectron, i needed the remote choke for my bike due to the larger fuel tank, if your wondering if you need one for your bike just go over it and see if you can easily reach the top of your carb, if you can then you probably dont need it, lectron doesnt list a remote choke for my carb but the sales team contacted me quickly and we worked it out, (it works great BTW), i didn't end up using any of the brackets they sent and isted just tuck it behind the frame.tuning, the important subject here, it couldn't be easier with the lectron, i dont even need to get off the bike to make the small adjustments, i just pull off to the side of the road, give a knob a little twist and im back back on the road again literally 5 seconds, and when i had to do a "major" adjustment i just pulled the tank off (i only need to because of my aftermarket one im sure with a stock tank i woulnt even need to do that) loosen the carb boots so i can rotate the carb and thanks to the easy tune kit i bought with the carb i dont need any more tools to pop off the slide cap, adjust the metering rod and put it back together, its a 30 minute job for a "major" adjustment, and thats only because of my aftermarket fuel tank, if it were a stock one im sure it would be 5 mins tops.in the end if your racing your dirt bike and want every last possible ounce of performance and have hours or days to kill, a shop to work on it in not to mention all the different jets you might need to tune it, then a pumper carb might be for you, but if your like me and just want to go have fun on your bike get a lectron it took 1 day to install and tune and im good to go.
