- I've been having a issue with the Smartcarb. Every winter when it starts to get cold and wet condensation gets on the slide causing it to stick. This causes hanging idle and run-away rpm's. The only fix has been to pull the slide off and wipe it down but this is not ideal to do on the side of the trail when the bike is dirty. Smartcarb has sent me their latest design with dimples on the inside wall of the carb that are meant to help with this problem.

I ride in the same area as you, been running a SC 36 for 4yrs now and initially had the same issue with side sticking.
Carb heater solves everything. No issues at all
I have the original cast version Smartcarb. Never had any issues over the last 6-8 years. I run ethanol free super unleaded and VP race gas @ 60:1 too 👍
Install a stiffer slide spring
I can't wait to see you on the 24 XCW TBI. The videos are going to be amazing!
Likely see me on a new 2T in the spring, have not fully decided which one yet.
I went through the exact same thing with the SC. It was extremely frustrating because they had me unnecessarily modify my air boot to address a problem it (the air boot) had nothing to do with. I am now back to the Keihin. It’s nice having a air screw adjustment again👍
Modifying or trimming the airboot would have no bearing on any issue like Greg mentions in this video and we wouldn't advise anything of the sort. Airboot modification may be necessary on some bike makes/models for proper venting, however such modifications have no effect on the stock or any other carburetor that may be subsequently used. If you still have your SmartCarb SC2 we'd ask that you reach out directly for the latest guidance. Happy to help any SmartCarb owner new or used.
You could try the STIC PWK metering block or their Super X carb. Mark @TokyoOffroad YT channel has 250 and 300 bikes demonstrates challenging mountain single track. Better performance than PWK's and his big dollar mods to TPI/TBI. I have my 200SX hanging with bigger bores at the tracks and it grunts on trails so well, I no longer need RPM or wheel spin to make power.
This is my Smart Carb story/experience 2 guys buy 2 brand new 22 Sherco se & 2 brand new Smart Carb ‘s, same day, we’ve been jetting carburetors since the 90s, Polished up the intake boots Yes you can get a iPhone picture down in the intake Boot My buddy gets his carb on the bike it’s working with minor adjustments except it doesn’t wanna idle, he’s scared to make any adjustments, it doesn’t run to bad. my carburetor is set up to run at 84 clicks, it’s starting to run better at 117 clicks, I was going to take it out west so I spent time off of work trying to turn this thing, it drove me crazy, every time I shut it off and let it cool down it was like a different carburetor had been put on the bike. I sent it back to Smart Carb and they told me it had a bent needle, have you seen how big that chunk of steel is 🤔they don’t just bend ? I get it back/put it on the bike now it runs at 134 clicks, I’ll admit one thing you can really tune it to run like a tractor on the bottom, or make it scream on top, but there’s nothing there in third gear but sputtering. Oh yeah I’ve never had mine idol. I do like how you can use a dial caliber to put the settings back to the original, they are accurate.
700’ at home, I found it completely useless in South Dakota Black Hills. I’ve tried to like this carb, I don’t want to hate it but 😭 The mileage difference is impressive and I’ve had great luck with leaving it upside down on the hill’s while I am laughing at what just happened🙃 apparently it’s too much to ask for your motorcycle to run as good as your chainsaw. I ride mostly hard Enduro, Smart Carb just won’t let me enjoy single track. Factory carburetor, pilot 38 main 162, And it runs perfect at 40° 🤔🤔🤔
Hey Bunky, we'd have you reach back out to us for tuning assistance to get your SC2 SmartCarb working properly. Records indicate that your SC2 was received, refurbed, and sent back in October '22. The bent A-Q11 metering rod was replaced at no charge. They're 440A stainless but are still susceptible to bending upon even mild impact, especially with the weight of the throttle slide that they're attached to.
We'd want to take a close look at the installation, particularly the airboot trim and also the intake manifold clocking nib trim. The nibs that locate the stock carb upright must be trimmed flush to ward off potential air leaks there. We also recommend removing the stainless steel spacer on the intake manifold clamp to get a little extra tightness on the carb. Since that time we have introduced a new metering rod series: D-F developed in large part with feedback from the top US Sherco racers including Cody Webb, Cooper Abbott, and the satellite team. The new rod is richer off-idle through the mid for stronger bottom end response and is now the default rod for all Shercos, Riejus, and TMs used in hard enduro.
I had nothing but problems with my smart carb. I tried it on two different bikes , and never could get it to run right. Their customer service was ok in the beginning, but it changed as time went on. The funny thing is when I put the Kehin back on both bikes ran great . I ride 5000 to 10000 feet so the smart carb was appealing to me for that reason. I guess it works great for some people , but it was a total waste of money for me.
I'm having the same issue. My bike ran good through the first ride with the smartcarb sc2. On the second tank of gas the bike died and wouldn't restart. I sent it in for warranty work in the fall last year. I tested it last week and it still just floods out the motor. I put the stock carb back on and the bike runs great. I contacted them and they said sorry, you're out of the 6 month warranty even though the carb didn't work on the 1st try getting it back from warranty. I doubt the settings are so far off that it won't run because it did run good on its 1st tank of gas last year, it suddenly sputtered and died on a small uphill and wouldn't start after that and still has the same issue after sending it in for warranty work.
@@jacobcall1699 that sucks! Yeah they pretty much did the same to me. They said it must be something wrong with my bike. So I just happened to buy a brand new sherco 250 , installed it on that bike , same problems on that bike as my previous bike. When I contacted them trying to sort the issues out they were pretty much done with me. I since then did some research and learned how to jet the stock carb , the bike runs fantastic. I got rid off the smart carb . It sucks I really wanted it to work.
I just recently purchased a SmartCarb 2 for my older 2011 KTM-300 xc and I love it! When you install the carb you have to trim the boot so air gets through the carb properly + it's also recommended after the SC-2 carb is installed to ride the bike for 4 to 6 hours before making any adjustments. I bought the Billit SmartCarb 2 & it works & runs very,very good! One very small issue & Technology Elevated will tell you this and it does save some fuel & also you will lose a miniscule of low end but I put a 12 tooth front sprocket on my KTM-300 + just a quarter turn on the powervalve and the old 2011 runs like new! Give it a chance it is American made & I know you will iron the small issues out.
Lol. I’ve given it several chances. Five different carbs from them to be exact and ALL of them have failed. I’m glad yours is working well for you but here in the Pacific Northwest in winter when we have cold wet humid conditions the slide will stick. I have many examples of others with the same issue including two riders with the latest dimpled design. Unfortunately, they either only use the carb in the summer now or have completely given up on it altogether.
I had problems getting my 300se jetted right all summer, now that the air is colder it's running better than ever on the stock Keihin. I'll take that spare SC off your hands for the summer 😛
I experienced the same issues with my smart carb in a paramotor application. Sticking throttle and really bad carb icing compared to the standard carb. A carb heater solved it but was another faf I could have done without. I eventually gave up on it as the supplied metering rod which was supposed to have been correct for my application could not address correct fueling at both upper and lower rpm ranges. A potential great product but brought more issues than it solved for me.
Interesting information. I actually was fixing to order a smart carb even though elevation changes isnt my problem its more of climate changes. I work long hours and I was hoping the smart carb would allow me just go ride without having to raise or lower the clip. I live in Louisiana where it gets very humid so if humidity causes a issue with these carbs you just saved me a small fortune. I guess another reason to hate our humid weather haha. Merry Christmas
It’s the combination of cold, wet weather and high humidity. It may be be fine in you area, hard to say. All the new ones have the dimple’s which they say resolves the problem but I can’t confirm this.
I'm down in the swamp air SETX and my STIC Super X carb is rock steady, year round. It easily creates excessive power gains and the powerband gets broader and linear. Small bore magic for the low end. BTW, it's not a metering rod carb and it looks and weighs the same as a PWK.
I had the same problem with my smart carb on my 2018 300 xc. I sent it to them to repair. Cost a lot. After I got it back it ran great but decided to sell the bike and upgrade to a 2024 300 hard enduro xcw.
Have been thinking of getting a smart carb. Some great info here to consider!
I'm about to install one on a 2024 Beta Xtrainer 300. Definitely worth speaking with the Smart Carb team or jump on the forum it's great.
TBI 300…I love my Beta with the carb, but I find myself grabbing the TBI bike more often.
Hard to deny how good those TBI bikes run.
Hmm. Justifying a new KTM 300xcw are we? 😅😅 i just put keihin back on my 300se and love it. The SC2 is on my beta 200 and works perfect for that bike. No super cold temps where i live.
🤫 shh. 😂
Sorry to hear that and that's not a inexpensive carb. Hopefully they will give you a break on third one.
They are replacements, I would never have paid for the 2nd or 3rd carb.
I recall Morgan from Highland Cycles putting out a video last winter where a buddy of his was having a similar issue(freezing \ condensation) inside a Lectron Billitron they had installed.
I have heard of this on Lectron as well. Not Keihin though!
@@PNWEnduro The cold weather issues seem to be relegated to the "auto" carbs.
can confirm
@@PNWEnduro
It would be really interesting, if you know someone with a TBI XCW, to hear from you how it performs under the same cold and wet conditions.
It's fuel injection, it performs great. How does your car run in the cold? A carb is an immediate deal breaker for me.
@@OtisFlintThe only proof is to actually try it. Never assume. I’ve experienced EFI systems that did not work flawlessly.
@fredwernett while I've only ridden the new XCW in dry weather I have tired the new 250 and 300 XC's in the same wet winter conditions and they ran fantastic.
its interesting to see all the compromises we have in this sport in terms of upgrades we do to our bikes that benefits one thing but hinders the other. These smart carbs seem to be awesome for the elevation changes you got and both run very well. I have also had issues with the smart carb i had flooding my motor during a hard enduro and ruining the race for me. It seems smart carbs (although they work great) can affect reliability and keihins are always working (as long as you jet them) i have never heard this issue on a keihin and am curious to if it has happened.
I will say the new lectron pro model might actually pull harder than a keihin if youre splitting hairs. BUT i dont like how you cant customize the power delivery like a keihin. Its a one and done type of deal. You should try one out! Only downside is no 36mm
@@jamesoso259 no there's no variation in needles with different tapers. You get the needle for your engine size which is a linear taper and that's it. You can go rich or lean with it but it doesn't change the power curve just makes it not run how it should. Does that make more sense to you?
@@jamesoso259 then what doesn't make sense
@@bobbybecker8834 please reach out to us direct for assistance if you haven't already. We're happy to help. SmartCarbs work so well in hard enduro that we have some of the top level racers in the world using it in competition including Cody Webb and Alfredo Gomez.
You mention no 36mm size option for the Billetron Pro 38 and that is correct, but not because they're 38mm in size. They're 34mm measured. Anyone with one and a telescoping gauge can measure it for themselves. One of the key differences between the SmartCarb SC2 and the Billetron and Lectron H-Series is that the SC2 is true-to-size.
@@SmartCarbFuelSystems I did and bought a rebuild kit from you guys and did it myself. I ended up selling it to someone but he had issues with it as well due to getting dirt clogged in the float I believe and you guys cleaned it for him. You do have great customer service I will admit. As for the billetron pro I'll have to measure for myself. The one I have was sent out to me for testing as I'm looking to become a dealer for them. I'm using it on a gpx tse300 which normally takes a 38mm and it works pretty well. I have yet try a 38mm sc2 though
I think I agree with warren. I work in aviation where in flight temps get low and they do use heat. Carb icing is an age old problem. Hopefully the new design will work but in the meantime you need heat! Snowbike riders use some sort of heat shroud made from plastic to shroud the engine around the cylinder/carb and trap heat. Maybe you could even fab something although I agree you shouldn't have to.
What is wrong with the Keihin carb? Is the SC that much better in summer? I've never tried one but on my past 17 Te300, had a Lectron and loved it over the unsorted stock Mikuni. Never ran into this in dry Colorado... well... because its dry.
Love your content! Good luck and keep us posted.
For me the major advantage of the SC is not having to change jetting. I ride a lot of places from close to sea level all the way up to over 12,000' in Colorado so I really don't want to be messing with jetting all the time. It also gets great fuel economy at any elevation. Nothing wrong with the Keihin, it works well and is very reliable.
TE's rebuild kit came with 3 different springs. One of which had more tension, which could overcome the "sticking" you are describing. Then again, if you have been working with them, it seems this would have already been suggested if it was thought to be a fix...Those guys are sharp. I never had the issue you described. I'm also interested to see their new fix/design correction. Is it prompting a V3? Thanks for the video and information.
Yes, already using the stiffer spring. All orders will get the new design now but they are not calling it a SC3.
I love the concept of the smart carb and really hoped I could make it work for me as I ride year round on a Snowbike and Enduro. Aside from the carb freezing issue the other problem I had was fuel leaking into my cylinder and locking the motor. The first time I tried to clear it out it caught my bike on fire. I did a rebuild kit and had to readjust the carb settings close to 20 clicks which seemed strange. Then with the gasket design they have to sandwich the carb together it was leaking fuel with brand new gaskets. It’s a brilliant design but at the moment my keihin is more reliable.
Caught on fire? Damn!
Jason we'd have you reach out to SmartCarb direct for any tuning assistance. Snowbiking requires the use of a carb heater to prevent icing. We absolutely do not recommend using the SmartCarb for snowbiking use without it. Power Sports Tech makes a water jacket style heater specifically for the SC2 and that's who we recommend.
It's also extremely important to remember to turn the fuel off at the tank petcock while not actively riding the bike and especially when storing or transporting it. Carburetors aren't mean to be petcocks or positive fuel shut-offs. Any tiny bit of debris or stickiness in the float system can cause a loss of float control. By keeping the fuel off at the tank and both starting the bike before turning it on and turning it off at the end of your ride, you can greatly reduce the potential for flooding. Annual maintenance including a thorough cleaning and rebuilds with rebuild kit components every 2-3 years are advised.
@@jamesoso259 any carburetor can freeze or flood. And with any carb, the key to best results is proper use and maintenance. That means running carb heat to prevent icing, using the fuel petcock as intended, and keeping up to date on cleaning and maintenance intervals.
@@jamesoso259 they can and have, but more often they'll piss it all out on the ground via the external vent lines in the event of loss of float control. SmartCarbs are internally vented. Check-valves prevent fuel flow through the vent passageway but it can still go by the metering rod, slowly, over time if float control is lost. That is why we stress good petcock hygiene, include an in-line fuel filter with every purchase to ward off dirt/debris coming from the tank/fuel line, and recommend replacing all service parts with a rebuild kit when necessary, particularly the o-ring on the float needle seat. We use Mikuni seats and upgrade that o-ring to a viton material for durability but it will still degrade over time due to fuel exposure and pressure.
It does bring into question the trade-offs of not having an overflow . While I like the aesthetics and fuel savings of not having an extra tube, the downside of having the engine fill up with gas is quite major and seems to outweigh the minor benefits. I think I'd take the hose if given the choice. What happened to me was I tipped the bike over to do an oil change, and then stood it back up, without turning off the petcock. Everything seemed fine and after the oil change I went to bed. Came out in the morning to gas dripping out my exhaust flange, about 5 litres was all over my garage floor and the engine was gas-locked. Turned into a pretty big headache and took the better part of the day before I could get it running again and ruined the plans for that day.
It was my fault for not turning off the petcock, but the design of the SC2 makes it quite easy to forget this as it doesn't spill when tipped over and sometimes you can rely on that a little too much. With a stock carb I would've noticed the gas leak immediately and turned off the petcock. Would be nice if there was an option to have an overflow tube when ordering so we could get all the other benefits, without the worry of ever filling our crankcase with gas.
So is this caused by varnishes from fuel burning? IDKnow anything about this but I have been watching just to know this is
an option in some cases? Yeah, I'd be frustrated & I'm glad you're being straight up...... peace
Condensation from cold moist air being pulled into the carb.
@@PNWEnduro >> No, I didn't realize it ran warn enough to create condensate but you are the "Pro".... lol, I know
about condensate in Heat Pumps/Air Cond'rs & other crap but didn't know that happens in a carb? Thanks for the
share.... I wouldn't have ever known. peace
Great content. Appreciate the honesty.
I have been having the same issue. Carb works great until it's wet and cold out. Take it off and pull the slide and it has moisture. Usually a little grit too. The rep has said that I need to tape or seal around the cable boot better to keep that from happening. Doesn't seem to work. So frustrating. In September I was on a big riding trip and was having the hanging throttle issue getting ready to leave camp and I yarded that offer out and threw the Keihin back on. Problem solved. Almost chucked the smartcarb out into the bushes, I was so pissed. Seems when good dry weather it performs excellent like it should, but when wet, it somehow let's in moisture. Very frustrating. They have no fix for this yet. Don't know what to do. I've been on the phone with them too many times to count.
Let's hope the new design helps with the problem, although I'm about ready to give up and get a FI bike instead.
Thanks for sharing your experience. -potential sc2 owner
@PNWEnduro yeah, pretty frustrating. The bike runs premium with my Keihin when jetted for the area I'm riding and I would keep that carb in if I didn't ride so many different elevations during the mountain season. Even tho it only takes me 10 minutes to re-jet the smartcarb spoiled me not having to do that. I will definitely being buying a fuel injected Sherco when they come out in 2025. Stoked for that!
@ridgerunnersmc yes I wish sherco did not push the TBI bike back a year. I’m a little hesitant to buy the first model year of it. They will definitely need to shave some weight off the bike as well, it’s already on the heavy side without FI. The new frame design will likely address that a bit.
I had a problem with an open bellmouth carb on 2T engine with water droplets gathering on the slide and they would cause it to stick wide open, a stiffer spring stopped it from ever happening again, the spring cost £5 and a mechanic was trying to sell me a new carb for £200 saying mine was worn out at 8000K miles !
I wonder if a carb heater would solve the issue
Greg, thank you for keeping it real and sharing your latest experience.
We are always looking for ways to improve and refine our product, through constant in-house testing but also through feedback from users all over the world. SmartCarbs see some of the most extreme conditions related to elevation, temperature, and humidity across many different disciplines including amateur and professionally ridden off-road 2-strokes, on-road scooters, drag racing applications, paramotors/light aircraft, and more.
Air/fuel mixing, combined with low pressures and high velocities, cause all carburetors to chill cooler than ambient temperatures. When combined with cold air that is also high in water content, you have a recipe in some cases for carb icing and/or moisture build-up inside of the carb due to condensation. Unique to the SmartCarb is its extremely fine fuel atomization relative to other carburetor designs, resulting in an increased chilling effect. For that reason it’s extremely important to keep as much moisture out of the carb as possible through proper filter oiling/replacement, securing the throttle cable dust boot, ensuring all connections and clamps are tight, and averting moisture absorption in your fuel by using fresh (ethanol blends are more prone to pulling moisture). Carb heat is strongly advised for those riding at or below freezing temperatures in high humidity environments and especially those that are snowbiking or are otherwise experiencing snow immersion.
The dimpling feature has been standard on all 36-40mm SC2s for nearly a year now and serves to reduce surface area and any resulting moisture-related boundary layer adhesion that a small percentage of customers riding in these conditions may encounter.
We all look forward to your follow-up after running the newer SC2 and trust that it will now perform as well for you in the winter months as it does the rest of the year.
I'm pretty keen to try an SC2, but I simply can't justify the cost (AUD$1500) for the supposed return of benefits.
I have very mild winters where I live, so no issues with the freezing and sticking slide. Let me know if you want to sell one of your carbs 😁
I paid 1200 AUD for my SC 2 but that was 2 years ago the dollar was doing better. It's one of the best upgrades to my bike, much better throttle response and after initial tuning it runs the same at any temp, whereas the Keihen would always feel affected by temp.
Same problem, have to keep an Fi bike for winter riding in IA.
Imo might as well ride the FI bike all year then. The new TBI bikes are fantastic.
I have ran every version of SC, pre ordered the first version back in 2014. Everyone of them had the moisture issue, my fix was filing the blunt edge off the bottom of the slide. Helped a lot but in the winter when the SC has snow packed around it the slide would just freeze, standard carbs were too.
Is it too lean? I guess you tried a kind of richer setting for the cold season.
Put the Kehin on. i would run it year round only take a few min to re jet when you ride at elevation. I run the Kehin year round here on Vancouver Island. 165 main 38 Pilot nr8f in second clip i believe is the needle i use
I ride so many places and elevations, could be at 2000' on day and 10,000 the next. Not having to re-jet all the time is one of the reasons I run the SC. I have the Keihin on for now.
Try n8rg
I must be out of touch, this bike sounds fine to me. What am i missing?
Enjoy your reviews and would like to learn more about the issue with the SC in cold weather. I have 175 hrs on my 21 SE 300 with the SC2 and it has been flawless but I’m in the desert southwest so humidity and cold weather has never been experienced,yet. I was thinking of getting a fresh carb bike next year swapping the SC over to it so I like to learn more. Could the moisture be coming from your fuel? will wait to read more. Thanks
It's moisture from the air, always happens in the same condition, first few cold and really wet rides late fall/early winter with high humidity. With a dry cold it may not be an issue.
@@PNWEnduro So far so good over here in Alberta, put on about 15-20 hrs riding -5C to +2C
With 3 brain cells one can fondle the factory carb to everything needed.. the rest of us manage this art without having to winge n moan about an over priced paper weight.. for over 100yrs factoy carbs work a treat when tickled right.. learn how to tune a carburetor for your needs and ride on..
So you haven't had a chance to test the new design out yet, correct?
Correct, I have not even got to ride it with the Keihin back on yet.
Just remember with fuel injection and a dead battery your stranded. Not with Beta being carbed and with a back up kick starter, you will only get stranded once up in the mountains and you will instantly regret buying a fuel injection bike. Greetings from Van Island
Around 540 combined hours on my last three bikes (1 TPI bike) with no kick starters. Zero battery maintenance done and I've never had an issue. Not too worried about it but you can bump start the FI with bikes a dead battery if they have a capacitor.
Great review, Throw the Keihin back on. Don't wait for the Sherco F.I - KTM have been promising an app to tune the ecu (like Yamaha) for 5 years now, still nothing!! promises, promises 😞
No app to tune the ecu but those new TBI bikes run fantastic.
Yes they do,@@PNWEnduro
@@philipsmith6152TSP has a setup called ERM to tune on the go, but Ive got a TSP tune on my TBI and its so damn good its all I need
Some interesting info wasn’t aware the smart carbs were having cold weather issues shoulda waited to do this video seems like they are working to cure the problem and may have already, wonder if no ethanol fuel would help this? Especially in the colder months
I waited a year for the replacement new design, now I’m at the point I’m just about done with it. Three winters in a row, same issue. I unfortunately ethanol free is no longer an option in Canada but even SC said it shouldn’t be an issue as long as the fuel doesn’t sit long.
i have 400 hours of all season riding in alberta down to -20c on my lectron. only problem i have had is the throttle cable almost worn down and broke. i would very interested to see you try the new billetron carb. i fell like that could be the fix all for the carb bikes. on of my homies had a sc2 carb. it was a pain to tune and never really felt 100%
I tried the original Billetron, not the latest one with three circuits mind you. Lets just say that company has some quality control issues.
@@PNWEnduro that is seriously disappointing to hear. i have one of the newer mini billetrons. and the build looks great. but could have just got lucky twice
Alberta is so dry we likely won't run into this issue. I've put a good 20 hrs on my SC2 so far this year and no issues at all with carb icing up.
does your bike have a thermostat? \
Have you tried lectron? My idea was to get 2017 ktm xcw and pimp it out with best suspension and components to have maybe the best bike today. I think ktm has the best frame and engine.
I used the original Lectron on my 2017 KTM 250XC for a long time, when I put the SC on that bike it performed better. My experience with the new Billetron was a lot worse as you can see here th-cam.com/video/rPEBhnSyxbo/w-d-xo.html
Penso che Ktm sia il peggior telaio e il motore è difficilmente migliorabile.
Un amico che fa gare era passato da una vecchia Honda 125 2t a una Ktm 450, fa che a metà stagione il telaio era già allungato a differenza del 125 che ha usato per anni, ma quella moto gli han dato cambiando categoria, ma se ne dispiace.
Lean bike by 2 clicks, also when u finish riding, close petrol and run all petrol from the carb. That was my solution
What temperature outside air temp do you experience the issue ?
0-6 C.
Did you ever have an issue with heavy throttle pull? For me especially as the bike revs the pull gets very difficult. I’m using a domino throttle and verified the cable moves free without the slide attached.
No issues with throttle pull.
We ride the same turf, keihn for the win my friend. Nothing beats a crispy analog carb and you know it, youre just fighting it 😂 come on back to the dark side it aint that bad. I swap jets once a year and it takes about 15 minutes
I regularly go from riding near sea level to over 10,000-12,000’ and that would require jetting the bike every week. Not necessarily with the SC.
I’m on the stock carb for the winter and will be going to a fuel injected bike come springtime.
@PNWEnduro that FI should give you lots of new content to post about lol long live the analog carb. Keep up the good work bud
Spero in Italia di non avere questi problemi, l’ho appena comprato!
Comunque non pensare che con l’iniezione di risolvere, perché per ora hanno grossi limiti rispetto al carburatore.
Sei sicuro che smartcarb non da qualche soluzione per le tue esigenze, come i pre-riscaldatori?
Non vedo alcuna limitazione alle moto a iniezione di carburante. La soluzione era che mi mandassero un altro carburatore. Anche l'aggiunta di un riscaldatore di carboidrati può risolvere il problema.
@@PNWEnduro convinto tu nell’iniezione.
wrap a copper tube around the carburetor and plumb the engine water through it. It will keep the carb warm.
Bro😂
@@westcoastfriscoLOL. I have to admit it’s a far out idea. It’s the best I could come up with. Don’t I get some points for creativity ? :-)
It needs carb heat, like a Cessna
Yes, people have put heaters on these.
@@PNWEnduro does a heater solve the problem? I'm wondering how many watts of power is needed. With cold air constantly flowing through it I have to imagine that insulating it from the outside is pointless.
@Jrod_FPV I hear it helps, but I can't confirm with any personal experience.
As another person posted, Stiffer slide spring
I already use the stiffest one they make. Once the moisture gets any contaminants on it it creates a sludge on the slide. Stiffer spring won’t help that.
@@PNWEnduro pre-load it with a spacer. Is the slide DLC coated?
Has anyone tested the new design?
The dimpling feature has been extensively tested and has been standard on all new 36, 38, and 40mm SC2s shipped starting July/August 2023.
Buy another bike, one for the winter and one for the summer. 😂
New bikes are only 16K! lol. I have two already, not for different seasons, but for different types of trails
First!
First reply back!
*feint whisper* XC-W 🤭

I've had 3 smart carbs now. 2000 KTM 380 and a 2019 gas gas XC300. Mietering rod carbs are trash. Nothing beats a traditional carb with a handful of brass. It's a stupid expensive gimmick you and I both fell for
Clint, he specifically states that he loves it 9 months out of the year. The issue at present is quite specific - a narrow combination of extreme humidity and cold temperatures inherent to where he rides at this time of year. Too much moisture in the carb.
Encourage you to reach out to SmartCarb for assistance and the latest tuning baselines, especially for the GasGas. The new D-F series rods are fantastic which is why we have Alfredo Gomez racing with the SC2.
