    Could not be more pleased with the purchase. Have about 60 hours including an off road racing series and multiple track days.
    Have a YZ250 but have a 325 kit with a rekluse clutch so was concerned about how the carb would perform. The combo was phenomenal and is testament to how flexible the carb is. Pulls hard off the bottom and is linear all the way through the RPM range

    Install was very straightforward, flipped up the rear subframe and had no issues. Would recommend using your phone (or other camera to make sure the there is no obstruction from the air boot, I had to trim mine slightly. Bike literally started in 5 kicks with a new top end. My 2015 YZ250 has no clearance issues with the rear shock either, it initially makes the air box touch until you sit on the bike.

    Initial tuning was pretty close from Technology Elevated. I really appreciate the fact they listen to each customers specific application and send a tuned carb for your platform with baseline settings written on the manual. I’ve heard complaints about the carb not being capable of change but I’ve had mine from sea level to 5K (MSL) in varying temperature and humidity conditions and I cannot tell the difference between my friends FI bikes and the SmartCarb. Another thing I like compared to FI is you have the capability to adjust to your liking, if the bike is to rich or lean it’s literally a 5 second process to get where you want to be. Additionally I’ve had friends with electronic FI issues, which I never have to worry about.

    The off road races started from “dead engine” condition so I’m familiar with starting quickly and the bike fires first kick every time if I do my job. In 60 hours of riding I’ve never had a starting issue.

    Fuel economy is dramatically better. Have not done a mileage test but for reference I could run a 2 hour off road race on the stock YZ250 MX tank, which is incredible and couldn’t get anywhere close to that before.

    Bottom line, I won’t have a bike with a conventional carb from here on out, really pleased with the product.
