Was skeptical at first when I ordered the Smartcarb for my 1981 Yamaha XT250, with having so many issues tuning an aftermarket Mikuni VM30, and original carbs being close to the same price as a new Smartcarb, I took a bold move that paid off. My bike has better fuel economy and takes throttle like a champ now. It’s a must-have for dealing with older bikes, with modified exhausts and intakes. Straight out of the box it kicked over in one kick, and didn’t even need choke, hadn’t had that before. Really stoked with the product here and how easy the install was.

Pull the trigger on 28mm Smartcarb for my Honda elite with a built 72cc polini corsa.After sending my build specs carb came in and the tuning was pretty close out the box. Throttle response is incredible smooth all the to full. My fuel mileage went up a ton. Bike runs cooler. I thought my PWK polini was a badass carb. But this Smartcarb blows it away. Well worth it.
