    I recently took a single track trip to CO with the plan of riding some of the “good stuff” What a blast! It was an incredible trip. I built a ton of tracks for my GPS of stuff I wanted to ride, and barely got to 1/4 of it… partly due to only 3 1/2 days of riding… partly b/c some of the stuff was so fun I had to ride it multiple times.

    This was my first time in the high country with this bike:
    2013 KTM 300XC
    38MM billet Rev. H SC w/ flange cut off stock air boot
    Gnarly pipe
    FMF Turbine Core SA Hardparts silencer
    Red PV spring w/ Kreft adjuster, dialed to how I like it.
    13-50 gearing (stock)

    At 1000′ in KC, I normally run the stock head that has been recut for better performance on pump gas. For the high elevation trip, I purchased a 300SXS head and had it milled for 8000′-12000′ on pump gas. I took the stock carb w/ a new air boot, kitted w/ appropriate jetting just in case. I didn’t want my trip ruined due to some niggling issue.

    All that to say… I didn’t touch any of the extra parts. The bike & carb setup was unreal! Crazy good, especially considering I was riding well above the tree line in many cases.

    With stock gearing, 1st gear was great for the gnarly. 2nd and 3rd were dialed for moderate to fast paced flowing ST. 4,5,6 were only used for transfers. It had a stupid amount of low end grunt for the gnarly stuff, & I rode lots of that. Some of the terrain would have been difficult to hike through, let alone get a dirtbike through. It was amazing how it lugged & refused to stall… absolutely no need for an auto-clutch. It chugged & churned, but would respond with authority when asked.

    I wish I had a more scientific fuel mileage estimate, but I do not run a gauge cluster, and just used my GPS for mileage for the day… sometimes forgetting to reset the mileage. Doh! I never ran through a stock tank full in one day, but easily had 60 miles on a not-quite-full tank to start, with plenty more to go… never hitting reserve. I’m guessing I could have rode 90-100 miles of reasonable riding. That’s just a guess though. Fuel mileage was much better than my buddies 200xc-w with a 3.3 gallon tank.

    I had a submarine moment where I drown my bike & had to dewater it. I was trying to hurry through a section to meet up with some buddies on the other side of a pass. I came up to a water crossing that I had been through in previous years. It was larger & wider, but did not think much of it, trying to make time. I wheelied in, landed, and water poured over the seat, into my pants, etc. I got one more blip of power, then blaaaaaaahhhhh.

    I had to push the bike out of the crossing. I thought… oh no… with this carb, how is this gonna work?

    I rested the rear wheel against a stump and tipped the bike up to empty out any water from the exhaust. I then pulled the plug and ran the starter. The exhaust and motor was full of water. The air filter was water logged. I was 15 miles from anything, way in the sticks. I went through my routine as best I could. I cleared the air filter, slapped a new plug in it, after getting as much water out from the plug hole & exhaust as possible.

    It started instantly and I went on my way. I put a new air filter on when back at camp and never experienced another issue.

    Now, after about 30 hours on this carb, I am a raving fan! Everyone who rides the bike is too. They are mazed by the crispness and rideability of the bike, epecially when they compare it back to back with theirs. In fact, I went riding today with a friend who now has to have one too! ūüôā

    Thanks for a great product & great customer service Corey! I am watching in anticipation for your future products. You continue to elevate the game in a way that provides accessible drastic improvement for an average Joe.


    Looking back, I can’t believe that I’ve been running a SmartCarb for 3.5 years & over 250 hours on my 300 XC-W. All on the same top end. There is no way I’ll be going back to the OEM carb and I really don’t see any benefit in a FI or DI system due to the added complexity they would bring, given how trouble free the SC has been.

    I usually ride in a few local enduros/hare scrambles a year. One is the Sandlapper Enduro just outside of Columbia, SC. I’ve won my class at that race three years in a row and two of those races were part of the National Enduro Series.

    Thanks again for the “electric motor” feel of the SmartCarb!

    As an “early adopter” of the 36mm billet Smart Carb, I have enough time and experience to confidently say this is a game changer if you ride a 2 stroke. I have over three years of riding over two different bikes and have been continually impressed with the performance. The smooth electric power band from the torquey bottom to the stout over rev makes my 2012 KTM 300XC much more enjoyable and less tiring to ride. Also, the “set it and forget it” jetting aspect is not an exaggeration. As an example, in February of 2014, I was riding in the northeast in 20 degree weather and snowing at sea level. I then took my bike to Arizona and rode for a week in the mountains in 85 degree temps and 5000-6000 feet without ever touching an adjustment. The bike ran great under both conditions. Try that with a Keihin!

    Lastly, I would like to mention how great Corey and the Technology Elevated staff have been to work with. Corey has graciously suffered through my questions while tuning and has been available to provide advice on weekends and evenings.

    Get one, you won’t be disappointed.

    Installed 36mm billet SmartCarb on my 2009 KTM 300 XCW. Construction appears to be high quality. Install was snug but no modifications were required to the airbox. Did not need a new throttle cable. Stock cable is fine. Bike starts and idles very well. Carb was dialed in at the factory for a 300. My bike has a 250 top end on it now. Runs very well. Feels like increased over rev even with an older restrictive Gnarly pipe. I think it is running a bit rich, possibly because it was dialed in for a 300, not a 250. I decided to not touch the clicker when I got it. It is running well and I still haven’t bothered to adjust the clicker. Hope this billet will fit the 2017 KTMs or 2017 Huskies but we will have to see about that.

    Speak about SmartCarb is very easy as use the carb, performances really increase power, increase fuel economy…..forget jets, forget screwdriver to set air screw, just two fingers and make the setting, never found a carb like this on the market and then you have a Billet carb with an amazing look, just one word: PERFECT!!!!!

    And Technology Elevated has a fantastic aftermarket costumer care……a carb to try….

    The SC2 36mm on my ’19 Husky TC 125 is a game changer, fits perfectly and runs like a dream right from the get go. Idled nicely out if the box, super crisp throttle response from bottom to top with great over rev. This is my 4th SC and the SC2 is a great carb, well-made and comes with supreme support – always quick to answer questions without judgement. I use this bike for pure MX, the carb goes way beyond off road, works wonderfully with my engine package too. Stop the tuning madness and step up to a Smart Carb 2, worth the expense.
