I wanted to let you know the carb is working great! I also wanted to let you know I passed your company’s info on to a few people from the Kayo KT250 site after my review to them, as they were very interested in your product! You guys make a quality product and I don’t mind telling anyone who asks😉. The low end grunt this bike has now is crazy! It’s getting more and more rare to buy something that 100% lives up the company claims! I’m pulling hills in second and third gear that before was in first! Anyway, thanks again for your help, and your great product! I will recommend this carb to anyone that rides multiple elevations and at differing temperatures.

I do a lot of vintage motocross and I have a 72 CZ 125 that has been modified and built by Harry Klem. With a Mikuni it ran ok at best, was impossible to start kicking it, but would cease in off throttle situations going down hill. 1/2 size bigger pilot jet and it would bog and load up. I bought a lectron and tried three different needles and just about every setting with them and got it to stop loading up but throttle response at low RPM was poor at best. I decided to go with a Smart Carb and gave them my info, bolted it on, it started first kick. I was beyond words and thought it was luck. After a couple small adjustment it ran like a reed valve motor. ZERO bog, quick response off idle, it would do throttle wheelies without pulling on the bars for the first time and was a beast on the track. Simply amazing! Given the option, I don’t see why anyone would buy any other carburetor for a bike!!! Why would you want something that you have to take the slide out to make adjustments? Why would you want another carb that cant possibly give off idle throttle response like the Smart Carb? I would give it 10 stars if I could. It worked so much better than I thought was possible, way beyond expectations!!
