PRO SERIES Carburetor Kit for 4-Stroke | Precision Fuel Delivery, Peak Performance, Ultimate Simplicity (38mm-40mm)

My 2008 WRF 250 runs amazing after installing this carb! Easy 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.

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.

Ive heard the hype around the lectron carb for about 7-8 years and as someone who works on power sports as a side job, Ive messed with a few bikes that had these carbs from 2 stokes to 4 strokes bikes and four wheelers. I never did get one till about a year ago and coming from a guy who had rebuilt and tuned hundreds of stock and aftermarket carbs, I never want a non lectron carb again. Adjustments are super easy, even the slide adjustment can be made in less than 5 minutes. Your bike will run smoother and crispier with throttle response like no other. I was a little skeptical about the metering rod technology at first, but Ive yet had to adjust anything at different elevations. Great product thats worth every bit of the money.

I had a few issues getting the carb in. Not anything with Lectron. I am just a bit OCD and removing the back frame enough to pull the boot to the engine and air box wasn't giving me enough space to pull them back on all the way. So I removed the whole back frame and drilled 4 holes I'm the Air box and it looks amazing. Was having a few issues with getting the bike started after it was installed so I called Lectron and Hunter was very helpful and told me the setting for the idle screw they had on their bike and waited for me to take an engine bracket off and remove the gas tank to adjust the metering rod. And I let the bike cool down and start it a couple times and it works way better than the stock mikuni carb it had in it.
