Hello! My bike carburetor was overhauled and serviced. Went on a ride in Arkansas and it shut off when I got up to speeds between 65 - 70 mph. Has anyone had experience with this? I took bike in, initially for this reason the first time. Mechanic said it was the carburetor. I don’t want to get rid of it but I need some direction on what to do with it. Please help a lady rider out!
