Idle Screw
Turning it to the left lowers your slide height and your idle. Turning it to the right raises the slide height and your idle. If you adjust your idle too far down and the screw locks up, reach inside your carb, raise your slide up, and turn your idle screw clockwise until it catches again. If you lean out your rod, you will have to turn your idle down, and if you richen your rod, you will have to turn your idle up. Wait until your bike is warmed up and clears out before adjusting your idle.
Metering Rod
The metering rod is used in combination with the vacuum from the motor pull fuel from the float bowl. The flat side must always be facing the motor to do this. Don’t adjust it without running it first. It comes preset from the factory, and tuning it on the stand will not accurately represent conditions when the motor is operating under load at the track or on the trail.
To tune the rod, remove the slide and hold the slide to where the rod is pointing towards you. Turning it to the right will richen it. Turning it to the left will lean it. What you are doing is either threading it in and shortening the length of it (.006” per ¼ turn), or threading it out and adding length to it. Then, push the rod in towards the slide to collapse the spring and turn it back to where it is facing the motor to save your setting. You can use a set of calipers to measure the length of the rod and get back to the starting point (on your invoice).
Power Jet
The power jet is used to fine tune your top end and works like a faucet. If you turn it to the left, it opens the valve and richens it. If you turn it to the right, it closes the valve and leans it out. Tuning this has nothing to do with your idle or low to mid-range throttle response. NEVER ride with a closed power jet. If you are riding dunes, deep sand, outdoor motocross, or snow where you are wide open for extended periods, we recommend going ¼ turn richer to keep your motor cool. The fuel level in the line will be even with the level in your float bowl until the power jet is activated.
Cracking the throttle open is not enough to activate the power jet. The motor must be pulling a sufficient vacuum with the slide height over the bottom of the jet nozzle for about a second. Trying to activate it on a stand will usually not work because it is not under enough load to pull enough of a vacuum before revving out.
Most two stroke dirt bikes running pump gas will come with the power jet open between 3/4 of a turn and 1 1/4 of a turn from bottomed out.

I have a Lectron carb on my 300 for a few months. Rode long trails, rocks, mud and sand sections. It works very well. Very crisp and very responsive.
Just to make sure I put the original stock Keihin carb back on this week-end. After a whole day of re-jetting it... I must admit. The Lectron suits me better.
I can get a crisp jetting on the stocker, but there's always a spot that's off . Different weather/location and the whole jetting has to be re-done.
The Lectron hands-down is smoother everywhere. These should come stock on KTM and Huskys. Seriously.
Noticed that the stock carb DRINKS much more gas. Noticeable on the trails.
Much less spooge on the exhaust with the Lectron. Even the smell of the exhaust is a bit different. These guys have something right going on.
So happy with this carb. CANNOT go back to the stock carb.
Actually thinking of getting these carbs for all my other bikes, including the minis !!!
Great job guys.
Thank you for your excellent feedback!
100% agree. Great reply.
been using these for various applications for over 20 years. awesome system.
these carbs kick ass. Thanks David
I just literally bolted one of these on my completely rebuilt 08 KTM 200 and love it. Took it up to 2700 feet on an 45 degree overcast day and it ran great. I may richen it up a half turn on the needle, but its so easy to do and understand what you're doing!
That's great to hear, Brett!
hey kevin,just ordered mine this morning from slavens, im the one who called u a few days ago for the 2017 150 sx from ontario, they said they wont have the cam for the odi grips till next week and they will send it soon as they get it,im pumped cant wait to try it, thanks for ur help!
Best video on how to install and tune ,Thanks
I put these on my rd400 and wow are they great .very easy to tune and understand what's going on. I'm getting these for my rz350 and honda cb450
1:23 I always like to punch in or pinch in the air boot big spot on the center to open the round part towards the carb. Easier to move it around if you have a close fit. From there place the carb into the intake boot. Then when you let the air cleaner boot go so it pushes its way onto the carb.
Just installed my new Lectron 36mm on my 14 KTM 250 XC-W . It's late so gonna fire it up in the morning.
Somehow I knew it did not have jets on the bottom like any common carburetor, and I thought it couldn't be adjusted or , if it could, it would be a nightmare. I was so wrong, this is beautiful.
There is a REMOTE choke system available for bikes where the pipe is on the right side and the choke knob a bit hart to reach.
Im definitely gonna buy one for my YZ 125
After adjusting the metering rod and klicked it back into the spring load check that the rod has the SAME free play on to each side.( centered).
Helmut Clasen that's what I was wondering, only comment I've seen on this. Mine came not centered.
Put the weather seal on!! Just bought a bike running lean went to adjust it all sandy the boot wasn’t on and the cable much smaller. Things seem clean on other side so gonna try. The reeds are letting light in so may need parts.
Man I wanna get one of these so bad. I know they’re an amazing product but they are a pretty penny
Nice
mantap bos.👍👍👍.
"Be careful not to turn the carburetor over as the slide could fall out and be damage now at this point, turn the carburetor over" lol Thanks for the video fellas, it helped a lot...
Sweet im going to get one for my RM250 since its simple and self adjust with altitude. Plus my buddys KTM300 ran great in Utah. Just deciding on the Legacy MX or High Velocity.
The High Velocity gives you more bottom end and mid-range, while the Legacy is more top end biased. You will be impressed with either.
So if your float bowl always goes to full when turning on petcock, how do you adjust this? And why is choke on the exhaust side?
can you make video lectron install to yahama 125zr?
For some reason this handy 2T vid does not show up on the full list under the channel, some tweak needs to be made.
I saw a comment where someone wants one for the Minis. Do they make. 21 or 24 mm carb? Something for a performance scooter?
But how do you know what the needle height should be for a normal start up?
Its a pain to get my 1999 rm250 carb in and out of the frame. Not nearly enough room with the solid air boot. I hate my stock carb. I have an annoying bog just before the powerband should hit and it won’t open up. If you pull in the clutch and rev it out it’ll open up. I can’t wait until I can just get one of these
This will be my next upgrade to my 96 dyna. Will be showcasing this carb on my UA-cam channel doing the mountain passes etc on a 2000km ride.
I bought a electron for my sons yz 85 first put it on. It was awesome. Now. The bike bogs out when you give it gas. Put new spark plug in. Clean everything Tryed to do a few adjustments on card. Still same. Can you please help me with this ?
may I repost your video / content in the automotive section? 🙏🏻🙏🏻🙏🏻🙏🏻I like tegnokogi
Mine KTM exc 360 / keihin PWK 38 / 54 KM Lectron + - ?
Hi sir, can you suggest your carb size for my bike?
120cc (bore 54mm/stroke 51.9) been upgraded to 133cc (bore up to 57.25mm),
No PV,
Duration 10k rpm.
Much appreciated.
Does it need power?
Do you have lectron 50mm?
I have an after market FMF header and exhaust on my ktm 125sx. Am I going to have to change any jets or any thing with this carb?
No only thing you might have to do is play with the air screw and adjust your throttle
I don't know what bike that is but it sure has tons of room to mess with the carb. CR250s frame is right in the way.
They had the gas tank off of it, that's the only reason they had room
After adjusting,my idle screw is Will not engage.do you know what this could be caused by?
06 KTM 250xcw can't get it to idle and have to keep giving it slight amount of throttle to keep it running. If I give it too much throttle it wants to bog and die. What adjustments should be made to my metering rod and/or power jet?
First, turn your idle up. Then, richen your rod in 1/4-1/2 turn increments.
How would you say the bike does on increase in fuel economy with the Lectron Carb?
We get a lot of reports of folks getting around 20% better than a well jetted carb, but we've had reports of over 60% before. There are a lot of factors that go into fuel efficiency.
But on your Website it says: The Lectron can not be adjust on the dyno jet, because the engine is not getting anoth load to create a vacuum
Hi how to mix air
I have a yz 125 for mx, how put a 36mm or 38 mm lectron? the yz 125 have a mikuni 38mm. the lectron needs to much adjustments? or it's only install and run? I live at 0 meters altitud and the 10/ 35 ° Celsius
$465 + Shipping for the 38mm HV kit (includes carb, cable, and adjustment tool). We will set it up as close to your specs as possible. It may require minor tuning depending on personal preference and bike set up. You can order it here and fill out your specs: www.lectronfuelsystems.com/index.php/off-road/yamaha-yz-2-strokes/yz125.html
can i get one for my yz 125 02
Ok
Somebody know which tool Size I need for the small screws on top?
It s so poor for Europe that the tool is not with the lectron. Because here we never need this sice of tool😡
It s only in USA used
I was told that Counter clockwise leans the metering rod ?
The manufacturer just went over the correct procedure, go with that (yes counter clockwise leans / drops the rod).
I keep it simple with the Lectron... Right to richen and left to lean on adj....
I bought a used bike with a Lectron billetron carp on it. I still need to fine tune it but is there anywhere we can find the factory base setting?
Hello bc - could you please email your complete bike specs including your serial number from the carb to sales@lectronfuelsystems.com
อยากรู้ราคาในไทยครับราคาเท่าไหร่
Sit pra eu comprar pra minha dt180 aqui no Brasil??
Dá perfeitamente, compras um para 170cc e está bom
On mine, the tank thing that one the bottom is full with gas, not halfway like yours
Lectron Carb can use at Yamaha 125zr?
cant fit, the dimension of the carb is tall and the bowl is big, ( size lectron ni tinggi dan mangkuk minyak dia besar, so x muat - lagi besar dari carb tzm, carb tzm pun jenuh nak masuk kt 125
My bike wont start when its cold,starts awesome all day first kick after i get it going.leave it 2 days and it takes 30mins to start.any ideas?
Shoot us a message on FB, and we'll be able to get back to you faster. The first thing I would check carb-wise, is that the choke is working. When you get your bike started and warmed up, pull the choke up, and let use know if it changes RPM.
hey was away on holiday,finally managed to get it started after draining the carb,is there any way to do that without removing the whole carb? and the choke doesn't do anything when i pull it up with bike running
Replied on Facebook. We'll get you taken care of.
mine does same thing.after first start it kicks everytime and runs sweet all day.let sit overnight and refuses to start unless i lay the bike on its side for 10 or 15 minutes.it starts right up after that.why is this.
@@blainezinn2874 clean your carb thoroughly and check that your float bowl is working to manual spec. Don't twist the throttle at all when you are kick-starting it until it is running. Use choke when cold start. Check jetting is in spec for climate temp and elevation. Put in a new spark plug. Clean and re-oil your air filter. Check your Reed vavles are not curled. Don't let your bike sit long time periods with gas in the float bowl. Keep fresh premixed fuel running through it. Rev engine to high RPMs more often to clear it out. Don't bog it down so much.
Why do you have to take it apart before installing
The slide has to come out in order to install the throttle cable into the carb. After that, adjusting the metering rod is how it is fine tuned.
How to set my carb main n pilot ?
Block 62.50 mm
Carb 28mm no power jet .
None of our carbs have mains or pilots!
How carb control the oil ?
28mm? Keihin or mikuni's? Because this video for lectron carburetor. I can suggest you to check out graham bell guide to 2 stroke book for your settings.

Right richer, left leaner; remember that and you will know how to tune lectron
Nah. The power jet adjustment is opposite of that.
Debating getting one of these but the $500 price tag is pretty hefty.
Worth it
can for rx king?
Onok wong jowo jebulo😂
Hi sir. Im from philliphines. I have a motor bike. Suzuki 150 4strok. Can i buy your lectron sir
Ypu can buy it via lectrons website sir.
Việt nam. Hello ..!
How much broo???
5 bills
Why did you skip the next step of the installation process and move on to just putting the slide back in.
a honda with ktm plastics ? lol
Hah! Thats the same as putting a made in china sticker on a BMW...
The video on the dyno wasn't the same bike lol
***** NO. Hondas are good, KTM is sheit...
@@Namesakes.unit-x-10sq10 ? Bmw is made in china. And harleys.
@@theravedaddy Harleys have worse quality than most China items tho... I didn't know bmw's were also made in China, in Europe we only get the German made ones.
