Smart Carb cost - $700 (add $75 for TPS)
Lectron Cost - $475 (includes throttle cable)
Both carbs ran fantastic on the test bike.
Both of them gave similar advantages over the stock Keihin carb.
Both carbs seem to dump less fuel on the ground
Better throttle response and properly metered for elevation and temperatures.
Both carbs have a nice idle adjustment that can be done without tools
Both carbs offer different metering rods for the end user to customize their tune
SC2 has no vent hoses (only a float bowl drain hose) so some might say that is a cleaner look.
Lectron Pro over Smart Carb
* Cheaper cost - Smart carb is $200 - $300 more depending on options - that is about 50% more.
* Translucent float bowl to monitor fuel level (stuck float situation)
* Doesn’t require trimming on air boot for the internal vent scoop like some models do on SC2
Smart Carb Pro over Lectron
* Choke on the correct side
* Tune the carb with no tools externally while bike is up to temp
* Uses Stock Throttle Cable
* 5mm shorter end to end making it easier to fit on install
* Has option for TPS which might give you the option to install on a couple other models
Notes -
* Have heard of two instances from SC users where the carb pumped fuel into the cylinder when in transport, or tipping over. One gentleman had this happen to him twice. Filled entire engine crankcase with gas. Important to shut the rule petcock off. Have not hear this from Lectron users as of the filming of this video.
* I’ve heard SC users and Lectron users tell me they have tuning issues with their carbs here and there. Neither one are fool proof. I’ve not had any problem with either.
Bottom line -
Yes, the SC2 carb allows you to tune the bike without tools, but at a cost of $200-$300 more. Keeping in context, I have installed the Lectron or more than 10 of my own bikes (I own 3 of them right now), Tuning for me has been a one time thing when I first install on the bike. Most of the time I’m close enough with NO TUNING, but some times, I need to turn the metering rod about a half turn. That is it. I’m done after that no matter where I ride. 3000 feet to over 10,000 feet and they run great. 30 degrees to 105 degrees. I’m not sure the extra $200-$300 is worth that to me at this point of my life.
If having the choke on the left side of the carb and not having to pull the slide off the bike once or twice in the beginning is worth the sacrificing th $200 - $300 to you, then go for the smart carb.
If you don’t care about the choke because you only need it a fraction of the time the bike starts (many times even when it’s cold I don’t need it), and you don’t mind taking a few extra minutes in the beginning (possibly) to set it up, and you like the feeling of $200-$300 in your pocket, I know the Lectron works very, very well. - Auta a dopravní prostředky
Have a Lectron on my 2001 RM 250 I kept blowing spark plugs and haven't touched a spark plug for 2 years now ! Lectron is a win win and it delivers !
Lectron doesn't have a phone number ANYWHERE on their website. Smart Carb does show their phone number prominently on their "contact us" page. I submitted an email inquiry to Lectron over a week ago and haven't gotten a response. No way I'm spending $500 with a company that I have no way to contact after the sale.
Alot of people say they're rude and the customer service is non-existent
From the looks of it they seem to be shifting their business into more of a dealer model. Not sure. Anyway how's your 28mm SC2 performing for you on your Freeride?
Their phone number is 100% in the top right corner of their homepage. I have never once had any issues with them or their customer service. Lectron has helped me and taken the time to answer my technical questions anytime I have contacted them. As well as SmartCarb. Both are exceptional companies with good customer service!
@@SmartCarbFuelSystems Ironic. The guy that complained about the company not getting back to him hasn’t gotten back to you.
@@2old4allthis many potential reasons why. Could have simply forgotten to. We consider no communication to be a good thing - assuming that the SmartCarb is working wonderfully and that the customer is happy. If they aren't then we expect to hear from them. There's no reason not to contact us for assistance. That's why we're here and we're always happy to help.
Cheers!
Didnt talk about smart carbs egg shaped venturi. Didnt mention smart carb is a true single circuit carb. Didnt mention the reason to vent lines, as it draws its air in through the air box instead of drawing unfiltered air like most carbs. Theres more, but just a few quick points to make for those watching. Great video. I ran the lectron, smart carb, and STIC back to back on my Gas Gas XC300 to find out the same thing. I was sold on the smart carb, but they were not as expensive then either.
I have the smart carb
I have two SC's. The second one SC-2 required zero adjustment and runs great. The knowledge base over at Tech. Elevated is expanding. The machine is a 363cc TRX. I love that I can run at 30 degrees at 1000' and 70 degrees and 6000'.
I run the lectron on my 1990 fxr, huge upgrade over stock.
You do some great videos mate, thank you for taking the time to share with us.
Kudos to you Kyle. Overall you do a great job on evaluations.
I've had the same Lectron (with different rods) on a KTM 150XCW, 150SX, YZ250, and now Husky TX300. I just access the choke from the right side of the bike. Reach in behind the frame, over the pipe, and ta-da. I actually kind of LIKE it there because the petcock and fuel lines aren't in the way. FWIW.
What he said ^
I bought the choke extension for the Lectron. It makes it very easy to use the choke.
Lectron would be cool for out west riding but at a cost of 1/3 of my used bike seems a bit steep.
I've compared both back to back, and my pick is the Smartcarb. The Lectron ran great, but the SC2 is noticeable crisper down low. With the ease of adjustability and noticeable low end gain over the Lectron, I can see why the price is higher.
What about the stock carb. I heard it hits harder
@@TruenorthmtGod there is a small trade-off in tq, but it runs smoother and feels less likely to stall with the Smartcarb. The left small trade-off is worth it.
Yes or no.
Did you exhaust (correctly) all OEM adjustments?
Did you change anything else other than the carbs, (gearing, pipe, etc.)?
Now tell the truth. That's all. :)
I am looking at the Lectron. First time I heard of the smart carb. No offense to anybody, just my opinion. Personally, I stay away from products that are claiming to be "smart", because it seems to me they may be designed to keep us stupid. :)
@@EarthSurferUSA what did you find? Is the lectron alright for the price?
@@EarthSurferUSA smartcarb and lectern are made by the same inventor and based on the same principle over all. The smartcarb is the newer version which is more refined and has more features.
Lectron on my 2018 TX300. Bike runs perfect at all times, all temps, any elevation.
Good vid kyle , I have run a lectron and found it worked well I recently fitted a Stic module to my 38 mm Keihen carb on my 18 -250 exc , all I can say is the bike hooks now lol ,and reasonable fuel economy still , i ride single / 2 trail rocky conditions this was easy to install and set up ,I can’t offer anything in regards to elevation and temperature ,I run at 300 meters above sea level generally from 10 deg C to 30 deg C ,the Lectron and Smartcarb might well be better options for elevation / temp etc just depends what your priorities are ,this bike is close to my 18 Husky Tx300 in terms of torque etc the other thing I have noticed is how easy the bike starts I am sure it’s possessed lol been riding two strokes since 85 never seen a bike start so easy ,anyway this is another option for carby guys .i bought my Stic module from Tokyo Offroad think it was about 370 US who is very easy to deal with ,I am not affiliated with whoever produces the Stic or Tokyo Offroad just my honest opinion I think you should try one ,cheers d.👍
Love your content. Keep up the good work!
My Lectron has been great . Slavens Racing Mule HV says do not touch any adjustments and call if you think you need to. One time the bike sat in the enclosed trailer for a week during hot hot weather. The bike did get access fuel in the crankcase . I blame the heat 100* type stuff causing the tank to pressurize enough to force fuel through the carb . Yes the tank is vented but that's all I can think of. I rarely turn the fuel off. It doesn't leak fuel in transit. Other than that one time it has been flawless.
Great reviews, beautiful family, awesome customer service and the best fitting shirts I can find. You're killing it Kyle, keep it up brother(son). 👌
Can you put a lectron carb on a 2018 110?
I just got a Ktm 125 sx on Saturday and I love it!!
Nice man I’m getting a ktm 450 Xc-F next week
Lil Croissant that’s awesome! Ktm fam!
Running the lectron on my 02 yz 250 an love it. Didn't know they where invented by the same guy that's pretty cool. May have to look at the smarty a little harder for my next bike. Nice info! Thanks
Very interesting and informative episode
Pretty happy with my stock one
Love your vids Kyle
We have had differences in professional opinion, but I think you sold me on the Lectron carbs, especially with all the seat time and variety of bikes you have used them on.
Originally, I just wanted to get rid of the electronics and power jet on my 2019 YZ250 stock carb. But the way these carbs stay in tune, with the price of fuel today, (you will save fuel, especially if you never jetted your carb.)----well those are pretty hard to deny for deciding factors.
Thanks man. Nothing tells a story better than intelligent experience. Doug in Michigan
Excellent video mate
Ok. He just needs to do a lot more technical talk on how they perform. I’ve had both and I keep going back to the Kiehin due to the superior power characteristics. Power delivery would be more important to talk about vs price. Anyone can look up the price and dimensions.
My Lectron has way better to end power than the Kiehen. Like reeves to the moon type power and gets 30% better fuel economy. I would try again and get Lectron staff to help you. They’ve been awesome
They both made the bike run extremely well and I wasn't able to tell any noticeable difference. I said that in the video. They made the bike run fantastic... but you can do the same thing with the stock carb and some tuning.
The only tuning issue I had with a Lecron on my KX500 ice racing bike was float height. It came slightly too high and was flooding the engine out. After adjusting that, the bike fired up no issues from sub 0 to +40 f spring race weekends
When I was 18 I bought a new 01 KX250 on the "Kawasaki Good Times Credit", almost bought the 500 when I saw it was around the same price, I think cheaper actually, and the brochure said it would hit triple digits....stock. But I bought the 250 because I was 160lbs, and it was a great bike. But now I wish I woulda bought the 500 and kept it. I ice raced and dominated most of the time, I can't imagine what that thing feels like on the ice. Keep it pinned man!
David I had this exact same issue on my kx500. Once adjusted, it’s a dream.
Hey Kyle really Digg the Chanel! I'm an older guy (50) and I'm strongly considering getting back into dirt bikes. I used to live and breath motocross as a kid but have twisted a throttle in over 30 years! Considering the YZ125X or the new 2021 KTM 125 XC 2-stroke? Just say'n thanks is all! Love that you're geared to enthusiasts, keep'm coming brother!
just got the lectron h series on my bike, have about 6 hrs on that carb already and my bike rips, all my friends say it sounds good and dialed .
Only adjustments i made was turning the idle screw because it was running way to high idle out the box.
3 years later 2023....Lectron Billitron is out w $7 stock cable adapter, choke on left side and drastic improvements to power curve on lower half of the scale vs older Lectrons....and then only since May '23 the 'Pro' billotron w low throttle angle torque jet is out for even more low end on top of that(no fuel mpg increases anymore on that one) ....really no upside to SC except the external top knob metering rod adjustment instead ofnpulling the lectron apart. And now the bottom end is there w Pro version to wax any old school jet carb. Lectrons website has a phone number on it and they answer every time. They have been known for TOP NOTCH cust service w proactive follow up tech calls and email responses. I got a billitron pro for my cr250 and eventually will probably get a SC for my daughters KLX140 since they make one specific for it or the BBR big bore kit(170cc). They are both from the same dudes mind cant go wrong.
There is no direct affiliation between the two companies. SmartCarb had the good fortune to work with the original inventor of both technologies, William "Red" Edmonston before his passing in 2007 and have continued advanced development of the single circuit metering rod carb concept ever since.
Having tested both the 38 Billetron and 38 Billetron Pro we see no discernible improvements in performance compared to earlier versions. Ease of use with stock cable acceptance and correct choke placement, yes. Easier starting with the "torque" jet, yes. Like the HV and H Series before them they are 34mm carburetors when measured at their narrowest cross section just behind the slide. Metering rod adjustment still requires slide removal. Conversely the SmartCarb is true-to-size (the size you order is the size you get), has that full external adjustability, and provides superior fuel atomization using only a single metering rod circuit due to its patented, integrated float bowl venting feature to assist fuel flow at all throttle positions. Proportional at-manifold float bowl venting with no dangly hoses and no need for secondary or tertiary fuel circuits.
Our setup for the KLX140 stock or big bore are rock solid. Reach out when ready and we'll set you up!
Good review Kyle. Been thinking on getting one of these for my 2013 Beta 300RR, and now I think I've made my final decision.
100% recommend the Lectron.
The SC2 is so much better than the lectrons on that 300!!! Bottom of second and 3rd gear with the lectron sucks
Good channel. Seems like straight shooting:
I have seen the same thing happen with the lectron filling the crank case with fuel because operator error by not shutting off the fuel.
I dumped my lectron and went back to stock. Love the stock carb on my Yz125x
Lectron my17 250xc works great. Love it but the choke on the wrong side has always bothered me. Electric start with kicker and I need to use the kicker more due to how stiff it is to open out to get to my choke.
Looking at both for a TC85 trail bike for my kid. Which one starts more reliably with one kick? Which one has less tendency to flood when tipped over? Which one clears out the flood easiest?
I have had both, smartcarb had nothing but issues. Lectron was spot on.
Me n my friend Danny watch ur videos your the best Carl
His name is Bart 😂😂😂😂
I like how clean the Smart carb is! Plus it has a blue tube. Lol!
I have an old Suzuki LT-250 air cooled 4 wheeler (1996)and was wondering how a smart carb would work if possible. I would much rather preferer to not have to mess with elevation adjustments etc as well as cold and warm starts.
If having to purchase parts for new throttle cable, they might end up being around the same cost after those expenses are added depending on your unit.
I put a jd jet kit in my muckini mis spelled but don’t care,
But the jd jet kit gets better fuel mileage than other 300’s running lectrons and runs more crisp just sayin bud keep up the good work appreciate your videos and time. Keep riding and stay safe 👍🏻
I have 2 Lectron Carbs. 1 in a highly modified KX500 and 1 on a Yamaha blaster. On my KX it changed the game. I could get it to idle, with 1 metering rod adjustment, the bike runs beautifully. The bike even sounds different. It’s like it’s always in it’s sweet spot. I’d say power is the same but the bike is so much more user friendly. I will say however it did fill my engine with fuel one night when I forgot to turn the petcock off and had fuel dripping out of the power valve shaft on the floor. I have heard from multiple sources that the lectron will do this if you don’t turn off you petcock every time you stop it. It’s just a risk each time you shut the bike down. And with a big 500 kick start, you do not want to flood a bike out remotely in an area where you can’t push start it. That piece I don’t like. The blaster has run good right out of the box with the carb, don’t have a lot of rides on it, but it has been good. Sounds like there is a similar issue with the smart carb with the needle seat leaking and overfilling the carb/bike by. This I don’t understand because with 35 years of dirt bike riding I’ve never had a Mikuni or Keihinn do that. I’m sure they do but I just haven’t had it happen. But I have had it happen with a $500 Lectron, in my mind that should not happen.
Nice honest popping
Thanks mate, thinking about one of these for my CR500R engine in a CRF450X frame, cause the carb on it works great when riding but dumps a shit load of fuel on the ground and I like doing long rides and although I’m yet to run out of fuel with the price of synthetic two stroke oil I hate wasting it, and if I put it on the stand for a few minutes I have to turn the pet cock to off, and there has been a couple of times where I forget to to turn it back on which is kinda dangerous in certain situations,
plus I don’t even know if I’m wasting a lot of fuel the same way while I’m actually riding. 👍🏻
Kyle I have a smart carb. Do you notice that the carb thats comes on pwk. Hits harder. I here that alot.
I wonder if the slides are bouncing open repeatedly during transport. It could also be the check balls inside the SC pumping under vibration.
I was turned off by aftermarket carbs after I bought a lectron and the slide was warped or something due to quality control causing it to stick wide open blowing my motor after my second ride. Took the thing apart and the slide was ceased in place. Love the idea, wish I could try it again, but after spending $500 on it in turn blowing a fresh $2500 custom built race motor I’m too scared to try again!
i would like to know if the lectron carburetor can be used in your daily motorcycle, i know it's design for performance but i see that it says that it's also good in fuel milage. Something else i want to know is how the lectron carburetor works on non-motocross bikes so... i really want to know some comments about using it in the street and for daily commute. Thanks !
How about the autonomy of the bike? How much more miles you can ride with a fuel tank? Against the stock carburetor?
I am the second one watching LOL. Awesome videos Kyle
Ohh, I thought the choke on the Lectron right side would stink a bit after you mentioned it. But, with the kick starter out, (which I will use), I can reach that side fine. Nope, the pipe will not be hot. :)
Just jet the stock keihin to perfection. It works great for wide ranges of altitude and my 300 got better mileage with jetted stock carb over a friend's lectron. JD kit is easy and works.
It got better mileage because it has a lean spot when you are at low rpm and high throttle input. A big reason that the Lectron is better is because it doesnt have that lean spot. It yields more precise and prompt throttle response, which shines in technical terrain.
I have both. Lectron works great. Needs to be tuned after large changes in temperature through the seasons. (Summer, Winter). Smart carb worked great and needed to be tuned after large changes in temperature aswell. However the smart carb apparently had "needle seat o ring failure" and dumped gallons of in the carburetor, cylinger, airbox, and even the header pipe. Around 2 gallons to be precise. This was not "slow" as stated but happened very quickly. Enough to completely flood the motor within a couple minutes. That is a very dangerous design flaw. So I will be rebuilding mine and getting another Lectron.
In conclusion wich carb actually makes the 2strokes run better/crispier, better throttle response?
Have you tried the newer version of lectron? The Lectron Billetron PRO?
I've just fitted a lectron to my sherco se 300 and it came with a remote choke so it can be on what ever side you prefer and they do make some lectrons with the throttle position sensor
Per Lectron's own site they say that they will not develop TPS for their carbs: www.lectronfuelsystems.com/tps_faq#:~:text=What%20does%20the%20Throttle%20Position,to%20help%20it%20run%20cleaner.
@@nathandyess5310 just going off what the dealer said
@@allaneccleston389 no worries.
I got the lectron hv38 for my ktm 125sx. All I’ve had to do was turn up the idle. It was kind of set it and forget it. (It’s been installed for about a year now)
Thank you for not buying a 250f
Kyle I have not heard of anyone using a smart carb on a yz250x...do they make them for the x? If so do u know how they perform ?
I always left my petcock open bike started fine every time
I love these videos buy can you do a lectron or smartcarb vs a PWK with the STIC metering block installed. Please o please man
@Mateo Nieves well if your bike comes stock with a PWK it's cheaper than a lectron. But if you have to buy a PWK then its roughly the same price. The power gain are so worth it. It feels like you bolt a supercharger on your bike. And it compensates for altitude. It's the real deal
Kyle, have you had a chance to compare the newest Lectron "Pro" to Smartcarb SC-2? There are lots of comparison videos out there but they are obsolete now that lectron has the new pro model. I am trying to decide which one to get, each seems to have its own advantages.
i have a 2004 Cr 250 that came with a smart carb installed , the previous owner said he ran the bike on 40:1 , i have been running it on 32:1 . The bike is in excellent shape , if the smart carb was built to run on 40:1 but i run it 32:1 will that cause hard starting issues ? The bike has good compression still , thank you .
I would like to get a 38mm smart carburetor for a cr250 but who sells them or where can they be bought?
Nice video
Awesome comparison Kyle! How about performance? Which one gives a better low end grunt climbing and which is better wide open?
They both made the bike run extremely well and I wasn't able to tell any noticeable difference. I said that in the video. They made the bike run fantastic... but you can do the same thing with the stock carb and some tuning.
So what one is better smart carb or electron
Give some consideration to the customer service. I'm happy to give SC my business given the reputation Lectron has.
Any review of the Billetron in the works?
Ok smart carb for me!! Due to I can afford it! If I am going to have a bike it is going to be the best!!
Just read this...Nice infornation, but a bit dated. How about a repeat testing of both now that Lectron has released the Billetron 38? Own a 2017 KTM 250 sx and have a modded Mikuni TMX, Keihin PWK with STIC and a Lectron Billetron 38 (Orange, of course.) Truthfully, with all the work done to the Mikuni, it now runs pretty darn well so long as the temps don't change too drastically. The Keihin I literally did nothing to, it came to me flawless. Even so, I added an extended idle/air screw and that was that. The Lectron took 2 tries to get the metering rod right, but it now runs flawlessly as well....Probably give just a bit of a nod to the Lectron, though, as the best of the bunch. Your video has given me the bug to try the SC2. Between 4 carbs and especially like you've done between the 2, it would be great information to have for a dedicated MX bike.
For me the biggest selling point for the smart carb is the TPS compatibility. This is also the deal breaker for me on the lectron.
Don't forget the external adjustability without tools, more than twice the adjustment resolution, true-to-size variable throttle rate venturi (not 4mm smaller like Lectron's latest H-Series and Billetron models), and internal/sealed float bowl venting!
What do you need a tps for?
@@SpeedDemonExpress my 22 yammy 250 and 125 have tps - there is an ignition map in the cdi
I would’ve liked to hear more on your opinion on performance ? Does one rev out more, more low end etc? I feel like that’s what people really wanna know. But other than that, great break down Kyle.
my bike revs out more, at least i feel so
i have lectron h series
They both made the bike run extremely well and I wasn't able to tell any noticeable difference. I said that in the video. They made the bike run fantastic... but you can do the same thing with the stock carb and some tuning.
Running Lectron on my KTM 300 XC, rather have that than a TPi bike. So much so I'm switching brands next time as I don't want a TPi bike.
Highly recommend Lectron. The choak on the other side isnt an issue at all. Not for me at least.
I tried the Smart Carb on my 2018 TX300 for like 5 weeks, always seemed to run lean. Put the Mikuni back on, ran fine, SC lean, Mikuni fine, SC lean. it was crazy. Finally had to give up and send it back.
Jd jet kit rips on the mikuni carb way cheeper
I used to live 10 minutes from JD Jetting. Great guy and spot on advice to get jetting perfect.
Curious, what are the stands that you are using in the garage with the casters on them? I need to get me a few of those.
Looks like they’re home made. 2x4s and plywood stained black with generic casters.
Will it work I on a125 chinese dirt bike ???
Plus electron puts the choke on the wrong side of the bike where you can't get to it plus I could never get my idol to quit fluctuating either it was low or high as they don't have an idle circuit
Did you try the Stic mod on the kehin?
I am asking because I just bought a yz125x
Not a fan of either one of those. If you want to make a significant difference in power delivery get a Keihin air striker & the STIC insert. Turned my 500 into a rocket & it really livens up the 300 nicely!
You forgot to mention the stock carb length. My 2019 YZ250 2-stroke stock carb is shorter than both at 75mm. (you measure 83 and 88mm) That is quite a bit, like 3/16" and 1/2" longer than my stock carb. Maybe different models have different lengths? I really don't want to compress my air box boot 1/2", (but I will if I have to), and I am not buying the smart carb.
Aside from tuning, how is the power both in delivery and peak HP between a tuned Keihin and either of these carbs?
Size for size and optimally tuned we claim 10% over dialed conventional carburetion (Keihin or Mikuni) at peak and we stand behind those claims. Charts are strewn across the forums and on our social media accounts/website. Have yet to be impressed with a Lectron on the dyno or on the flow bench.
I've got a Polini Dellorto VHST carb and had to drill out the idle jet tonight because it costs $80 to ship an idle jet from Italy, German, or UK. You say these carbs are Made in USA?
For our part, yes, SmartCarbs are made in the USA - namely Missouri with some turned parts coming out of Colorado.
What's this about carving out the air boot? Mine just fit straight in. Is it maybe a bike model year thing?
It depends on the bike model and/or year. Some bikes like the KTMs or Shercos require a slight trim inside of the airboot to clear obstruction of the SmartCarb's vent scoop so that it can vent. Proper venting is important for air density compensation (elevation/temperature) and also top end fueling. We cover the boot trim in a number of our installation video tutorials and advise customers individually when ordering. The Beta bikes do not need any airboot trim when being SmartCarb equipped.
Which one would you recommend for a yamaha banshee the smart carb or electron
We're a bit biased commenting here but our Banshee setups are fantastic. Reach out direct for guidance on kit/sizing recommendations.
I guess its plauseable if the carb has no over flows/breathers that it could spill out into the crank case if the fuel tap is left turned on every bump would let a little more fuel in and it has no where to go but up. It would have to be a very bumpy road but we have all at some stage forgotten to turn the fuel off on the way back from a ride and had fuel stain below the bike fromt he over flow. If the bike tipped on its side and the float was just open a little bit i can also see that filling a crank case over time. Normally if you did that the fuel comes out the over flow or side breathers. There is an advantage to no breathers tho and that is no chance of getting them blocked on a muddy ride.
Those works on 4t too?
no talk of power of fuel usage differences?
just want to know which one gave the most power gain. Should have put the bike on the dyno and tried both carbs.
I don't own a dyno, or have access to one. I'm just a dude working out of my home. The bike ran so similar with both carbs, I couldn't feel enough of a difference to talk about that.
so whats the advanage to change carbs out from the stock carb ? i have a 2011 ktm 2 banger ,,, never had a problem ,,, ? cheers steve / Australia
Not having to change jets when temp changes and elevation changes. These carbs self meter for density altitude.
You can buy a lot of brass, needle, and slides for the price of either of those aftermarket carbs.
The Smart Carb is just to pricey. I mean, even the Lectron's price is a bit steep as well for a carb, but it's not too far off from a Kiehin short bodies price. The Smart Carb, if they're argument is that it's more expensive because its billet and not cast, I'd say start making them cast then again and bring the price back down to stay competitive. A cast carb is going to outlive the bike more than likely anyway, so while the billet is cool and all, I'd rather save the $200 and have them make that SC2 more affordable.
Do lectron cables pop out like the smart carb? This is a bit of a pissing contest for an issue that doesn’t exist
has lectron fixed the issue with loss of low end torque compared to conventional carburetors ?
@@SmartCarbFuelSystems cool thanks for the reply !
Ok question for y’all out there. Anyone else have a noticeable increase in throttle pull with the lectron over stock? I cut down my slide spring and that helped ( and yes I already checked all the obvious things like cable routing, position, etc)
Yes, many of the Lectrons come with a stiff spring. You can request a lighter duty spring so it's not so hard to pull.
Yah I bough the lite slide spring from slavens racing and didn’t seem to make much difference. The arm pump is insane
I put a lectron on my 18 ltm 150sx because everyone knows the 17+ ktm 2 stroke carbs are JUNK. Totally transformed the bike well worth it.
For XR650L, Lectron is priced at $799. Why such a difference in cost from model to model?
4 stroke carbs are different and cost more than 2 stoke carbs
How well would a lectron or SC work on a 2 stroke supermoto for on the street?
Great, same gains. Once you have tried a Lectron vs stock carb you will never go back. Game changer
@@twowheelpilot Aight, i might have to save up for one. Because i use stock carb right now, and it doesn't really suit my needs.
@@nerfmaster33 You end up with more over rev too. The Lectron has what they call a power jet that draws fuel under load. They scream alright. Once set you dont have to fiddle with them ever again either. Most are perfect out the box however mine did need 1/4 turn richer.
So basically I can choose between a couple aftermarket carburetors, or a new bike? 🤔🤑
After you drop money on a new top end, including resleeving, because of a lean condition piston failure you'll learn to trust older stock carbs less too. Plus the resale on Lectrons is almost full price.
@@kevinfoster2308 I've got almost 85 hours on my stock top end and stock carburetor.
@@foolwithatool2052 the carb I'm replacing is 25 years old, thousands of hours on it. Plus where I live and ride can cover hundreds of feet of elevation, 30 degree temp swing in 5 hours, the relative humidity changes drastically too. Parts for a 95 are getting hard to come by. My hopes are that this actually saves me money in the long run.
@@kevinfoster2308 Well I guess in those conditions it'd be nice to have but where I live you have to travel about 200 miles to have a great enough elevation/climate change to make a difference.
Where are the carbs made? Could that be part of the price difference.
Both the Lectron and the SmartCarb are made in the USA. Price differences are due to the different manufacturing processes involved: cast vs billet CNC machined.
Is smart carbs only for two stroke engines?
They are designed primarily for replacing the stock Keihin PWK or Mikuni TMX in 2-stroke applications, however we are now selling and developing model specific kits for 4-strokes. More to come.
Hated the lectron, prefer a jetted carb, friend loves his smart carb, i now ride fuel injected 4T..
Do these carbs get Vapor Locked ?
It's possible, yes. We've only really seen it happen when a customer overheats the carb with a carb heater on a snowbike application. In that case opening the choke for a second does the trick. We recommend ball valves in-line for those coolant circulating heaters to turn down the flow some.
