28mm SC2 SmartCarbs are designed to replace conventional spigot mount top-pull carburetors in 2-stroke applications and will fit most intake manifolds and conventional air boxes that use Keihin PWK 28mm or Mikuni VM 24mm and 26mm carburetors. See dimensional comparisons in the photo gallery below.

Every SmartCarb is pre-configured with baseline settings specific to the application for which it is ordered. Questions about sizing, fitment, or compatibility? Contact Us!

Description

New Generation

We’ve spent years refining every facet and feature of the SC2, making it the biggest leap forward for our flagship model since 2012. This new generation fuel system provides the same unmatched performance gains enjoyed by thousands of enthusiasts in over 80 countries worldwide, only now in the most accessible, plug-and-play format we’ve ever made.

  • Shorter end-to-end (improved fitment over earlier models)
  • Revised throttle cable retention (works with nearly all stock throttle cables)
  • Float bowl drain screw now accessible from the side
  • Improved fuel line routing

SmartCarbs are designed and manufactured in the USA to provide extremely fine fuel atomization, precise air/fuel mixture control, and ambient air density compensation. These innovative features are delivered in a single-circuit, flat slide, variable venturi, mechanical fuel system.

Hewn from beautiful billet aluminum, our billet SmartCarbs have been crafted to the tightest tolerances in order to deliver the excellent performance gains that our customers have come to expect from SmartCarb technology.

  1. Keith S

    I installed the 28mm SC2 SmartCarb into my 2017 KTM Freeride and am a happy customer. I’ve put 30 miles of technical singletrack on the carb so far and have leaned it out 2 clicks based on plug readings and tailpipe smoke/oil as indicators. The installation was a breeze, quite a bit easier than the first model on a different Freeride due to it being a little shorter in length. I did trim off the intake flange stock carb locating nibs and cut off the stock carb drain hose bracket for better clearance. Love the simplicity of this design.

    Still a bit of work to do with the clicker setting but so far I’m seeing more power and smoother power modulation at low RPMs (roll on power). I ride technical singletrack in central Idaho from 5-9k elevation. I get through most switchbacks without feathering the clutch and have lost no torque with the SmartCarb; if anything the torque is improved. The jury is still out on the fuel economy but I’m planning a longer 50-100 mile ride before the snow flies to test that out.

    I got this SmartCarb to replace the stock Keihin on my KTM Freeride 250R. I ordered it over the phone and it was good to hear that TEC know my bike and what metering rod to use, to get the adapter ring and to cut a little plastic piece that’s not needed anymore.
    Shipping was quick and installation was straightforward. The carb is nicely machined and feels like quality. TEC had already set the metering rod and idle for my application and it was spot on so the bike fired right up. For tuning, make sure to follow the procedure in the manual (play with clicks first and adjust idle last). I played with it for a while but eventually ended up with the same settings the carb came with.
    Fueling is spot on throughout the throttle range and very reliable. I ride from sea level to 7500ft and hot to freezing, damp to dry and so far haven’t had to make any carb adjustments. I think I gained a bit more power and better mileage but that’s hard to tell for sure — it definitely didn’t get worse. I noticed that “luggability” got even better and power delivery feels smoother.
    With the Keihin I frequently had the engine cut out on me during steep hill climbs (worst possible moment) even after adjusting the float height. Problem is gone with the SmartCarb.
    Other things I appreciate: The carb is not spilling fuel when the bike is laid over and there’s no overflow/vent hoses that could get clogged or pinched or suck in water which was an ongoing issue with the stock carb. Also, the choke is on the left side of the carb and much easier to reach 🙂

    If you own a KTM Freeride 250 you need the SmartCarb. – No more annoying low speed stutter, instant starting, more bottom end grunt and smooth top end. Better fuel economy is also an added bonus. Fitting couldn’t be easier as it is a direct replacement to the standard carb. The team at Technology Elevated are extremely helpful and if you have any questions you can contact them by phone, or email and they are quick to respond.
    Well worth the money!

    For the last several years I have worked closely with the developer of the SmartCarb, Corey Dyess, to bring SmartCarb technology to GasGas Trials Bikes and I can now say that we have nailed it! I have the first production 28mm Billet SmartCarb on my 300cc Factory Replica TXT Pro and it performs absolutely perfect. I’ve ridden from 980 ft (here in Kansas City) up to elevations as high as 11,600 ft in Colorado with no adjustments necessary other than an idle screw tweak here and there to my liking. What a relief to never have to change jetting anymore for the altitude you’re riding at! The carb is very easy to set and can be adjusted without any tools or hassle by using the mixture clicker adjuster on top of the carb and once it’s dialed in, you forget it. The SmartCarb adds noticeable power from idle all the way up to the rev limit of the engine while giving very fine throttle control. You will experience a smooth and controllable power increase throughout the RPM range and I’ve seen my fuel economy increase too, which is also a big bonus! The SmartCarb improves every operational aspect of my bike and at this point, I’d be hard pressed to ride without it.
