- Hey guys, I am trying to find best jetting for my 2 stroke dirt bike KTM 300. I have been running Lerctron H series carburetor and had very good results, but in this video I want to compare it to stock Keihin PWK 38 with the jetting from JD Jetting. check out the video and let me know your thoughts! what would you guys run Lectron or JD jet kit? cheers!

2-stroke dirt bike JD jet kit vs Lectron on KTM 300
Very good review. I'm leaning towards Lectron. When I lived in HA. The Big Island, I carried another carb setup for high alt. just under 14000'. It was faster and easier just to swap carbs at around 9000'. Ride safe my 2 wheel friends.
Go smart carb, way better than a lectron..
thanks for sharing Randy, ride safe too
I had a Lectron for a while on my 300xc and had a lot of problems and constantly adjusting the meter rod. It kept bogging on downhill bumps and jumps. I went back to my Keihn and put a STIC metering block and now it’s the cleanest power I’ve ever had on a 2 stroke. I highly recommend the STIC meter block from Tokyo Offroad
thanks for sharing Sam
JD jetting is the best mod I have ever done on my YZ 250, once I installed and rode bike I couldn’t believe I didn’t do it earlier, thought bike ran right before but after I did the jetting it was night and day.
cool, thanks for sharing!
Worth the money, they have a chart you follow and everything figured out.
@ Michael pullins, not sure for the kx but I have the kit installed on my 05 yz 250 and it came with a different pilot, needle and an array of mains, I believe the magic is in the needle where the taper is not noticeable and in the stock khein needle you can see where the needle tapers. On my brothers 250f we also installed a jd jetting kit and we did not have to touch the pilot jet and it still made the bike run much, much better.
My bike like to bog while riding rough terrain and going uphills and sputters at the powerband and sometimes doesn't hit. Is my bike running too rich?? I've had the same jetting for two years and it acts differently now. I have cleaned powervalve and carb and float height is right
@@HaydenHowardH inspect the power valve
I replaced the jet block gasket on my 2018 KTM 300 XC-W Mikuni carburetor with one from JD jetting. Also put the JD blue needle setup in the Mikuni. I like the Mikuni better than my Keihin with a JD Kit. The Keihin lives in a box now.
All the Mook needs is a new gasket where the jet block attaches to the carb body. My original one was crimped from the manufacturer.
cool! thanks for sharing Joel!
Joel Cowdrey III Man I had the jet block gasket problem on my yz125 for a year and couldn’t figure out why it didn’t run right! Oem doesn’t sell it and I finally came across the jd gasket. It runs great again now 👍
@@tylernewsome217mikuni is junk it gave me alot of problems I put lectron on an it runs good I hate mikuni I got mad one day threw a rock at bike put dent in frame now I see bike I think of junk ass mikuni carb an all the problems it gave me an mikuni was new
The mikuni is a great carb, in stock trim it has a couple issues that are a real issue, but most are super easy fixes. The JD jet block gasket and jet kit make a huge difference for under $100.
thanks for sharing Bryce, appreciate it!
Yeah I’ve had zero issues with mine, put the JD kit in with the gasket and when I was changing it I could see the stock jet block gasket was about to fail so that’s a worth while investment. Jetting kit smoothed out the throttle everywhere
@@BoostedFB6 id really like to try the jd kit on my mikuni. I wonder how it feels compared to the keihin set up in the 2023 yz125x.
I bought a second hand Lectron from the wreckers for a good price to put on my older KTM380 that wasnt running too well..Gave it a good clean out..no mods and straight on..The transformation was unbelievable and even up to 6000 feet elevation with 35 F temps it ran exactly the same..wish I did this before I spent all the effort time and parts trying to jet the stock carb to give acceptable performance..For this old bike Lectron has given it a new lease of life.
cool, thanks for sharing Albert!
Wondering if you experienced bogging at 1/2 throttle to wide open by chance? I have a 2000 380 mxc and wondering if I'm too rich. Should I go smaller on the main jet?
I have a 2019 yz 125 , 2019 ktm XC 300 and a Suzuki Rm 250 2002 all with lectron h series and Boyesen Rad valve combo and I love them all !!!
cool, thanks for sharing!
I have a YZ125 and I am going to install the Boyesen Rad Valve but I can't decide on stock carb or Lectron. There is way too much conflicting information out there! Can you power wheelie without the clutch?
Josh L sure!!!!! It’s a different bike !!!!
Josh L yes
Thanks! Good to hear. Sound like I'll be ordering the Lectron carb
I've said it before, and I'll say it again. I'm always impressed with how comprehensive your video collection is. I'm considering a CRF150R for my son's next bike, but it seems like they are hard and frustrating to start and idle when cold. It seems like that could be corrected with proper jetting. I found out about JD Jet Kits, which is what brought me here. Why they don't come properly jetted from the factory is beyond me.
Deciding between a Lectron and a JD kit is hard. I like the way you said the Lectron is kinda like fuel injection, where it just adjusts itself, and you don't have tool around with it and get gas everywhere to make changes. But I like how much money you can save with JD. I live in Florida, so elevation is a non issue, so I'd probably go with JD, and hope I don't have to tinker too much.
Very educational video, which I appreciate very much.
right on, glad you find it helpful! JD will make you happy, I used it many times
They are sold with rich jetting for carbed bikes because the air quality is different all around the world, and even every hour in some places sometimes. So they have to be sold on the rich side to avoid engine failures for their customers all over the world.
Keihin PWK 38S is a very good carb when jetted correctly. I use myself Suzuki RM 250 NECJ needle in my Husky 250. Much better throttle response than with the original needles.
yes, its a really good carb once jetted correctly
your videos are getting really good, glad to see this comparison - subscribed!
thanks Vadim, glad you like it. Welcome on board!
I put the JD jet kit on my 2006 yz 250 I built. Couldn’t be happier with it. It rips. I know what it’s gunna do where I ride. I saved money and it’s easy if I go to the mountains to set up for that.
cool! thanks for sharing Brandon
Jd jet kit for me. I’ve put 2 in and both were spot on for my elevation going by there chart. Just adjusted the af. My sons kx112 I had resorted to going to 4o to 1 just so he wasn’t fouling plugs everyday. Jd I drained it put 32 to 1 in put it in and it was perfect, just needed a half turn on af screw. But I’m never in big elevation changes.
For winter riding I've been wearing -100 sorel boots and snowmobile gear. I live in northern Ontario Canada and rode all winter with my wife at our ice fishing shack where we go ice fishing all winter. For fall riding I wear a joe rocket ballistic insulated and armoured jacket with the rest of my normal gear.
My yz250 always works perfectly with the jetting that's included with the parts kit that comes with purchase of a new yz250, I run the 180 main in winter and 178 main in summer as per the manual suggested, works perfectly and I'm still on the original spark plug at 157 hours with original piston. I use Yamalube r oil mixed at 32/1 with shell gold pump gas with a lil splash of lucus octane boost. My wife rides a xr100 so my bike is lugging all alot of the ride.
thanks for sharing Ernie, you guys really know ho to have fun !
@@dirtniron someday if I'm lucky enough I want to travel out there to ride with you. That'd be fun. I've never been to western USA.
Great review Rado. I do not have any experience with the Lectron but the JD kits have always worked well for me, but the older I get the smoother transition/power curve I want on the throttle, I don't crave that hard hit as much anymore that the JD kit provides IMO. If you ever get the opportunity to try the SC2 Smart Carb I would love to see that review. Keep up the great work, stay healthy my friend
thank you Vince, I will have SC2 on my YZ250 build
@@dirtniron SWEET! Can't wait
@Dirt N Iron I use my rainjacket from the Austrian Army. It is just one layer but its really big an protects fine from the wind. And its big enough to wear the Protectors underneath. Nice video big effort, keep it up!! Greatings from Austria, Land of KTM ;)
sounds good, thanks for sharing brother!
I am new to the whole carburetor world. I recently swapped out my Keihn for a cheaper one. I am looking at rebuilding the Keihn and so far I have heard nothing but good things about JD jetting. I would like to invest in a Lectron or SmartCarb but until then I want to learn as much as I can about carbs.
if you have the cash its a no brainer lectron carb! after simple initial set up a turn of the screw with your fingers and your corrected for the altitude at idle and on! if not i think a little labor is much better! lectron carbs are kinda irritating to start cold but once it warms up the fun is on! :)
thanks for sharing, appreciate it
Awesome comparison and thanks for the tip about always riding in the same place which I do so JD for my CR250! Cheers
thanks, glad it helps!
I have always had very good luck JD jetting, but discovered that you have to deviate from the chart with the needle choice and clip position slightly.
richer or leaner?
Lectron it seams to be the best option for overal use.
smart carb, far superior than the lectron
yea, good carb
@@mixalis6168 not price per value though
Getting closer to 100,000 from when I was last here. Looking into getting another bike and watching your videos more. 👍👍
cool man, get something good and get it soon ;)
Dirt N Iron I ended up getting a decent 2018 yz125 I just put some sprockets and chain on it last night. Super fast
@@dirtniron You ended up getting to 100k .. next stop, 500 000!
omg have i really found someone who dosent engine brake on a 2stroke
haha, I try to pull the clutch in when on heavy engine brake, but little bit of engine breaking is fine.. cant really do it all the time. How do you ride ?
@@dirtniron have to use the clutch all the time because I live in fear that my top end loses compression and as a 16year old Finnish boy I have no job so even150€ for a new 70cc top end rebuild kit is a shit ton of money that's why i at least try to avoid engine braking:DD
what the hell is an engine brake! what are you a four stroke rider? LOL!! i cant keep of either one!
@@snowrider4495 alot of people just can't use the clutch on a 2stroke
@@gulag_dt I'm included! it's just a lever to take off with and the brakes to get off the bike and with the rest does not need the clutch or brakes while racing! LOL I'm into enduro and only use the clutch to climb things and pop the front end up to climb over things! I can not do a wheely to save my life it freeks me out! I can do it on a bicycle all day long!
Wow I'm impressed. I have spent 3.5 years restoring a cr250. The used mikuni carb I put on it to hard to jet. I just ordered a Keihin from California that comes with JD JET KIT. hoping for better. Results
$319 total from Ebay
thats a good deal!
I’ve always used JD Jetting and never had any issues
thanks for sharing James
Hi there I have done the same , and had the same thoughts and running the stock carby now
cool! thanks for sharing Dennis!
Good video Rado, well explained the differences and who what may suit what, good work. 🤙
thanks Mav!
i use the Fly Racing Patrol sized in XL which fits perfect over my body armor. Works great and has been durable for quite a few winter seasons.
Thanks for sharing Christopher!
On thing you can do that should be fine for your riding, (not super hard on the engine like MX), to change your jetting very quickly for a colder day, is use less oil in your gas for that day. If you change the oil/gas mixture, you are changing the amount of fuel that is going thought the jets also. I would stay between 32:1 to 50:1 with a very good oil for your riding, and I can roughly say that will be good for a 20 or 40 degree change in air temps. IMO, setting your jetting to 32:1 oil/gas mix on a cold day for a nice crisp plug, would be a good place to set anchor. I would not run thinner than 50:1 in any 2-stroke engine. The EPA may say it is OK, and force oil manufactures to sell it that way,--but no engine builder or manufacture would.
Interesting video. JD must put a lot of time in on jetting. I was expecting the Lectron to walk away with the comparison. Years ago I switched a CR480 keihin onto my YZ 465 to replace the mikuni. Was surprised how much more crisp the keihin was for me.
yea, JD has good packages for many bikes.. I like their products
@@dirtniron Thanks for th comment....I would love to see their facility and how they go about making up their jetting kits.
Aloha from Hawaii 🤙🏽 what kind of handle bars do you have on this bike? Your controls are setup really clean 👍🏽👍🏽
Excelent comparation.
Very interesting
Actuali I run a jd jetting kit, and bery happy.
Chears from Argentina 🇦🇷
Great to hear! thanks Martin!
I still have no issues what so ever running 3 different size Keihin PJs on my bikes. People make jetting out to be a horror show, just do some reading and talking with people who know what there talking about and you should be all set. With that said im still very interested in buying a lectron for my new bike build.. Im kind of leaning towards putting a 92-01 cr250 motor in the gen3 frame. Im very comfortable with those motors and like them more then the RCs. Time will tell. Sorry for the rambling this being locked inside is killingg me.. Off to dismantle a cr125 motor now lol
haha, thanks for sharing! no riding for you this time ? i can still ride without having to meet anybody, perfect for social distancing
@@dirtniron im riding just not on the dirt unfortunately. Taking the Electra glide out for a cruise right now. Stay safe brother
The 2002-2004 RC valve engines are just a little lack in power just nkt as good for some reason. But the year your talking about is a good engine
My lectron just works everywhere without me having to mess with it. I rode this morning and it was cold (only 28)when we started. Me and my buddy both on 17,18 KTM 250's. My buddy has his stock carb perfectly tuned but he had to mess around with the air screw to get his bike working decently and never really got it working as good as it could with the cold. Not that big of a deal but I've ridden from 4000'-13000' and 10-100 degrees and have never had to touch my lectron. I could probably get a tiny bit more power or punch out of other carbs but I like to ride. Not tune.
18 250s use a Mikuni not a Keihn
TT 17's too. I have one sitting on my shelf. Either one doesn't matter. They both have jets
Yeah ive heard the mikuni is 10x worse than the others in regards to needing to rejet it to make it work in the cold / hot ect
thanks for sharing Brian!
Hello! Nice review. The chart probably works best for stock engine. What if the bike have fmf exhaust and Vforce? Did you had to add fuel somewhere?
yes, I believe I did paly with the needle a bit and increase the main jet one size
For my 21 yz the jd kit is stock jets with a custom needle but does wake up the bike
where do you live? beautiful. awesome video. just ordered a kit for my CR250 and considering it for my YZ250 aswell. I have a lectron but think this may actually be the better way to go
i live in Socal
I like the carbureted feel, I want the crisp, snappiness of the 2 stroke rather than neuter it like a 4 stroke.
thanks for sharing Jason!
Apparently they state they fixed the crispness and snappiness people complained about on the H-series with their new Billetron series.
Have you tested the smartcarb? What do you thinck?
Way better than the lectron in my opinion.. best way to go!
no not yet, getting one for YZ250
@@dirtniron Will you do a video on the smart carb vs lectron carb please!!!!
Love your videos brother, very informative!!!
Glad you like them! thanks bro!
I've used JD jetting kits on 2 bikes and they both made more butt dyno power but the recommended jetting was way to rich on the 2 stroke and on the 4 stroke it was to rich on the bottom end. Still would recommend getting one but you might still need to learn to jet
yea, its good to get some jetting experience/knowledge.. its not that hard
Love your vid but id love to know where you get a lectron for 400 all the ones i see arelike 799 i think it will be jd jetting
that was old Lectron, they used to cost around $400 before..
Does the JD kit give you a variety of jets so you can fine tune it, or just a set to replace the stock jets? If it is just a single set of jets,---it can't be perfect all the time for your bike and area. But if you like the performance better than the Lectorn,---it's a winner just getting started.
Multiple
Need to do a review on Smart Carb to complete the test shootout :)
coming, got one for my yz250 build
Very cool videos. No BS. On the money
Great review and very useful information. I have a Question if this has been asked do excuse me. The New Lectron with the Yellow Sticker, with what metering rod does that come from lectron and also the measurement? I have the older lectron with the Red sticker on my 17 300 xcw here in South Africa and currently run the 4-2m Metering (set at 3.25 turn in) rod at sea level we mostly ride anywhere from 750 feet up to 3500 feet. I find this rod to be rich. looking forward to your response.
I dont remeber exactly, but it was same as in the old one.. I would have to check in the garage..
@@dirtniron ok let me know what you find. Thanks
Man look at those clouds ⛅️
beautiful, right
I'm going down the JD Jetting path on 2019 300XC looking forward to it thanks for the down low real good, keen to chuck an RK Tech head on too, do you have any other mods ont he bike exhaust etc?
fmf exhaust, vforce 4 and some porting
Really enjoyed your video!
Glad you enjoyed it!
Hey Dirt n Iron. That beautiful background, were is that?
Thats Thomas Mountain in San Bernardino forest. Southern California
Beatiful place.
My 98 kx250 runs really good snappy runs at 165 to 175 degrees im running 32to1 and I've only ran it for 15 minutes at a time and I'm not seeing hardly any smoke im afraid its lean i have jd kit but haven't tried it yet does it sound like I'm running lean
When properly set up the Lectron is better. Normally you get better fuel mileage and power along with rideability. You need to take the time to set it up correctly. However, properly jetting a stock carb is always the first and least expensive step.
how to you set your lectron?
yo solo hablo español pero me gustan los videos
I only speak Spanish but I like your videos ( I think )
Smart carb is for superior in my opinion and friends who have used them..
cool, I will have one on YZ250 build
@@dirtniron You will love it..
@@dirtniron Yes please, looking forward to your feedback.
Will you be doing a first impression or review of Smart Carb? Possibly a lectron vs SC vs TMX review? I have a 2018 YZ125 struggling with TMX fouling plugs.
I will have smartcarb on my YZ and will probably compare it to stock Keihin with JD jetting
Dirt N Iron Dobré! looking forward to it. Ran mine tonight with 102 race gas and it made it perfect. I just don’t want to pay 7.75/gal.
You should loop your overflow tube up and around the carb and you will not dump fuel out and get better fuel mileage, I have a lectron on one of my 01 yz125's and just got one for my 13 Yz 250, I was swapping carbs all last year testing lol, I changed the rod in the lectron for the 125 to try it on the 250 before the got one for that bike
thanks for the tip Mike, appreciate it
Hey Mike how do you like the lectron on your yz125, how's the low end on it, I just bought one last night but heard mixed reviews with lower cc bikes
@@christophgallo2347 the lectron carb is great , I had to tune it a bit after the first couple of rides, it was lean and had bad low end power and I couldn't tell until later on because I put the new lectron on a fresh motor rebuild and had to do heat cycles (low rpm/load) but after the heat cycles and tuning the rod it was good from top to bottom, great over Rev and bottom end power, better fuel mileage. the bike still ran when it was quite lean and didn't hurt the motor but i ran 16 to 1 for break in, ( took the top end off to inspect it after I found how lean it was)
Trying JD jetting on 2001 KTM 125 SX, had to go one size bigger than recommended for pilot jet to get good throttle response. Bike starts easy, idles good, really nice response to throttle to get the bike moving. However, sometimes the bike accelerates good past half throttle and sometimes the bike lacks power or cuts out just past half throttle. I tried going to leaner positions on the needle clip, but no change in acceleration when accelerating past half throttle. I am thinking of trying a bigger main jet and going back to the recommended blue needle clip position. All this is on a fresh rebuild of the engine. Does my condition sound like I am too lean on the main jet and needle?
Would be interesting to through smart carb into the mix too. (Obviously that cost more money)
i got one for my yz250 build
Dirt N Iron very nice. Will keep an eye out
Another great video!
Glad you enjoyed it!
What spring are you running? I'm guessing yellow or red the way it lifts the front end up!
His year of bike doesn't use different springs you adjust tension on the spring by screwing the adjuster in or out.
exactly, I have old bike 2004.. no different color springs just the adjustment screw..
@@dirtniron oh yeah I keep forgetting your bike is an older one. I consider mine an older one too but mine is an 08 with swappable springs. Either way, that thing is rippin!
Thumbs up on vids made by
Dirt N Iron guys, help him out because he helps us
thanks brother!
SmartCarb 2 is better than all of them. Been there done that.
what are the differences you felt. I used SC2 on my yz250 build, but never compared them back to back on the same bike
My 18' TE250 runs ok on stock, yet so much oil is always coming out my pipe, being in Australia we don't have much difference in elevation, can get cold in summer, would JD be the go to help with the oil? Just don't think lectron would be worth as we just don't have the elevation difference other countries get?
JD jetting will be a very good upgrade, I think they also have a kit ti fix some of the mikuni little problems.
@@dirtniron yeah I just brought one. I'll see how it goes!
Hello from Greece. I have one question. In my yamaha dt with 170 cc athena big bore kit. Zeeltronic cdi , exhaust especially for 170 kylinder , v force 4 reed, its worth it to buy 34mm lectron ?? Now i have one oko carburettor 38mm but in the middle of rpm i have little less power and in low and hi everything it's ok. What you think? Thanks . Keep good job👍👍
I think I would play with the jetting first.. but good lectron will run really good too
@@dirtniron i play with jettings ooh mayde 4 weeks every day. I buy from ebay others i buy from Greece after. I try a lot of stuff with filter with out filter i distraction from indian vespa 150 cc carburettor collar . A different collar to go in original filter box to work the carburettor with original filter. Nothing again. With full middle throttle everything was good in full throttle the bike dound like one person in the sea try to not drown . And i think the problem is the carburettor or the reeds .i dont have other explained. Anyway thanks for your answer . I thinking its time for lectron no 38mm but 34mm .i hope they work ☺️
Just wondering what kind of oil you mix in your gas and do you run race gas or pump fuel only..?
i just bought 1 gallon of Klotz r50 and I mix it with 91 pump gas
Indonesia present, i'm like your video👍👍👍
Thanks for visiting
I prefer keihin carb plus jetting, if I want to have experience like FI I would buy 4 stroke FI :)
haha, sounds good ;)
Yeah I just bought a keihin with a jd kit and it’s coming in the mail I’m over this lectron haha I want my bike to feel like a two stroke again I constantly tinker with the lectron to get more snap off the bottom but just doesn’t have it
2001 Yz144 JD jetting.. love it for single track in the South.
thanks for sharing Dustin!
I’ve also got the same bike with a 144 kit, just brought the jd kit, what jetting and needle/setting are you using ? Also what elevation, cheers
Yeah man, I'm at sea level in Texas.. but I think I'm either running a 185 main or a 180 main now that it's a little warmer and more humidity. And I think it's a 48 pilot.. and I'm also running 100 octane low lead aviation gas, which was recommended to me by JD jetting.. and I will never switch back to pump now.
Honestly I can't quite remember my needle clip position right now, I think it's 4th still.
But I also redid gearing to compensate for single track
My drz400 seems to have about 5 more HP below 55 Det. F.
try to drop needle one notch down during warm weather. Sounds like the bike is running rich in warm weather.
Thanks, dropped needle a notch and running much better.
Lectron all the way
thanks for sharing
What is your rpm at idle in neutral?
not sure the number, I tune it by ear
You ride without body armour ?
yes, I stopped using it last couple months.. doesnt fit well under the jacket..
Great videos! Sorry to hear you live in California.
haha, thanks man ;)
don't get a lectron, I did and it required just as much tweaking as a stock carb. Stock carb runs so much better, jsut elarn howt o jet it properly
wow cool
thanks Tanner!
"Jetting is not rocket science guys." I would be willing to bet that liquid fuel rocket science has a few similarities. :)
Yeah I’m sick of my lectron just feel like I lost a lot of bottom end always searching for a better power delivery off my 2019 ktm 300xc it’s smooth but not exciting, my friend just bought. 2013 ktm 250 xc runs a carb with decent jetting and it’s got more bottom then my bike...
Kirk, you might want to try Keihin and JD, it runs really well
Dirt N Iron just bought one put it in and it’s a whole new bike runs super clean and crisp with the jetting and my bottom end amazing now the bike just seems more alive than with the lectron.
Ill take a kehin any day over a lectron
I'll take a kehin any day over a lectron. Lectron are never crisp.
Thanks for sharing Adam
Kehin > than Mikiuni > Stic > than Lectron > than Smartcarb !
If you want looks of a supermodel and good performance Lectron, it does what it says and that floatbowl SAF!!!
Performance because if you are me I don’t look at my carb when I’m riding you guys maybe super flexible and ride and look at your carb at the same time, if your bike has a Keihin PWK and you ditch you don’t know your bike well and they’re are very good options for that carb at nearly half the price of a Lectron or Smartcarb that will do all and more!
Do your research!
If your bike comes with a Mikuni carb esp a 17-19 KTM or Husky then the cost to performance ratio is a different proposal and the 3 main options imo become a personal decision on what you believe is best for you.
Overall price?
Support by supplier?
Performance?
Reliability?
Buying a Kehin with a Stic MR is similar cost to buying a Lectron or a Smartcarb only you can make a decision at that point.
If yr bike has a Kehin PWK imo/e it’s a no brainer!
but as in these unprecedented times leading people to water is one thing getting them to drink it is a whole other problem, common sense or fat wallet you decide..a
haha, sounds good thanks for sharing ;)
Dirt N Iron You need to try that option sometime and test compare a video your findings, I am surprised this is still such an underground mod though I have seen some recent 500 builds using the Stic solution 🤙
You should compare the lectron vs the PWK with the STIC metering block
yes, I would love to
@@dirtniron get a hold them. They might send you one to test out if you ask

Spoilt for choice
What language is this guy speaking?
not the one my mom taught me ;)
It seems like you will promote whoever gives you free stuff. Not sure if you have ridden an FI 2 stroke but it's not like a Lectron at all, Smartcarb is the only one that comes close to FI performance.
is that so
Keith, if you or someone you know has a SmartCarb that's lean on top, have them reach out to TE for advice. Typically top end leanness with an SC is related either to vent scoop obstruction in the airboot or it may need a richer metering rod, but it's not an inherent issue with them. They've been used to set PPIHC records and are being tested and adopted by factory race teams.
@Keith Peterson, I’d encourage you to do some more research about the history of these products, their operating principles, and more recent customer and racer feedback. You mention APT, but that is a defunct company. The SmartCarb has been owned and sold by Technology Elevated for 5 years now. Full disclosure, I work there.
The first flat slide carburetor using a metering rod was the Posa-fuel and it came out in 1967. The inventor, William Edmonston went on to develop the Lake Injector, the Lectron, the Ei Blue Magnum, the Quik Silvers I and II, and eventually the SmartCarb before his passing. To say that the flat slide, metering rod style carburetor concept and the SmartCarb is undeveloped is incorrect.
SmartCarbs are sold in more than 50 countries and the claims made including 10% or more power, 30% greater fuel economy, reduced emissions, air density compensation, external adjustability, etc are the reality for our customers and sponsored racers, not just bluster from us. Third party dyno testing, including from JD Jetting himself, show that SmartCarbs do make power. The charts are on his website. Not exactly unbiased testing but the smaller 36mm SmartCarb held its own against larger 38mm Keihins, Mikunis, and Lectrons on top. They’ve been tested, again 3rd party, on drones up to 22k feet elevation with no changes in A/F ratios. Our racers continuously tout the ability to skip fuel-ups during races. And the product has been twice EPA certified for on-road use and produced the lowest evaporative emissions ever tested with a carburetor.
It’s not snake oil.
The 2 liter bottle and gas can analogies as well as your understanding of carburetor venting are also incorrect. Unlike the 2 liter bottle or non vented gas can, all carbs are vented. Vacuum or negative pressure do not “suck” fuel into the engine by way of jets or metering rods. Rather, higher atmospheric pressure falls/pushes into lower pressure spaces, which drives fuel flow. That’s true for any carburetor whether it be through vent hoses used by the Lectron and conventional carbs or through the SmartCarb’s vent scoop. The SmartCarb simply uses this phenomenon in a better way by using manifold absolute pressure to vent the bowl instead of just atmospheric pressure. By using both atmospheric pressure AND dynamic air flow inside of the airboot, the SmartCarb allows for fuel driving forces that are both proportional to the air density but also its velocity. That’s how it compensates for extreme air density changes and also why it, unlike the Lectron, does not require a power jet for sufficient top end fueling. All that to say that yes, vent scoop blockage in the airboot can hinder top end fueling in the SmartCarb. It’s imperative that the scoop be able to “breathe” and a trim of the in-molded rubber ridge in the top inside of some airboots is required. The KTMs are prone to having that rubber ridge and so in this case we would advise checking for and correcting for any vent scoop obstruction.
The short vague explanation of metering rod vs jet fuel atomization capabilities is also incorrect, mostly. You’re right in that the more finely atomized the fuel can be entering the engine, the more completely it can burn. The result is more complete and efficient combustion, and at proper A/F ratios, more power. To say though that jets provide finer fuel atomization compared to a metering rod is not correct. The opposite is true which is why you find many instances of metering rod carb customers talking up the improved fuel economy. That the metering rod more finely atomizes the fuel is precisely why these carbs, and in particular the SmartCarb, make more power using less fuel. The Lectron’s deficiencies in terms of power delivery are more related to its venturi shape and poorly atomized top end fueling through the power jet than it is about the metering rod atomization.
To make power, you need to burn fuel more completely… period.
😂
@Keith Peterson, speaking of snakes and snake oil, aren't you the guy at KPRacing that was partnered up with Boswell (aka InventorX-con) who created the STIC metering block? If so your baseless claims and understanding of the SmartCarb make a whole lot more sense 🤔
How's things going in the great communist state of California?
not that great.. but still going
Neither. SMARTCARB
My 18' TE250 runs ok on stock, yet so much oil is always coming out my pipe, being in Australia we don't have much difference in elevation, can get cold in summer, would JD be the go to help with the oil? Just don't think lectron would be worth as we just don't have the elevation difference other countries get?
JD jetting will be a very good upgrade, I think they also have a kit ti fix some of the mikuni little problems.
