I was going to post a video to show my problem with my reventon pro 1.1 but I can't seem to get it to work. A little history, I bought my first speedo motor combo about a month. My first speedo had a hesitation during initial throttle input (kind of like a cogging). I tried different motors, several sensor wires, changing from mod 2 to mod 1 software, and even different brand radio and receivers and nothing helped so I sent it back to get warrantied. I received my new one just in time for a long race weekend. What do you know the exact same result. I am baffled. I have a hard time believing that both of these are bad. I have reset my throttle points I don't know how many times and have played with my neutral point adjustments with the programming box thinking that was messing with it. Has anyone had similar issues?
