    Personally I believe a lot of riders do not know what a properly jetted bike runs like and surely don’t want to spend hours “getting to that point.” Nor can they identify a jetting problem from an ignition, fuel, PV or some other problem with the bike. I would put up with jetting that is a little off rather than “constantly fussing with it.” Yes, I change it seasonally but after that I just put up with it and ride. I bought a SmartCarb because I wanted good jetting and consistency. With the SC I can set it, forget it, and just ride; it doesn’t matter if it’s 40 degrees or 85 degrees out or if I’m at sea level or 8000′. Here’s another plus of these SmartCarbs, they are useful as a diagnostic tool, so if your bike isn’t running correctly you can pretty much eliminate “jetting” as the culprit.

    I wanted to take a minute and tell how happy I am with my purchase!

    I have a 1982 Husqvarna 430 that has been awesome to stare at but a nightmare to start. It usually takes me 20-25 kicks to get it going. Due to some surgery I had to have, my bike has been sitting for about 6 months. I just installed my Smart Carb following the instructions that you sent and the bike started on the 4th kick! It’s rare these days for a product to perform as advertised but you guys NAILED IT! I haven’t even had to make an adjustment!

    Thanks for saving me from selling my bike!

    I reached out to Corey and Nathan after discovering their technology on a forum for the 17-18 KTM Mikuni Carb issues. Being a competitor, I could no longer afford to question how the bike was going to respond to a new venue, higher or lower elevations, or changes in ambient temperature.

    I was able to fit the 38mm Cast SmartCarb directly to the bike with only minimal modification which they supplied and it was pretty well tuned right out of the box, only a few small tweaks to idle and the metering rod before we were off to the races. The bike was a totally different animal!

    Technology Elevated’s SmartCarb blew me away at how well it performed. No more guess work, no more hesitation, no more second guessing how the bike will respond to the inputs I provide.

    Thank you Corey, Nathan, and team for designing such a high quality product that is leagues above the rest. I cannot say enough good things about the design and am excited to continue racing with the product!
