the other day after warming up my sled i shut it off to get my bibs/ ect. on, when i started it back up there was no tach or speedo reading and the screen read SCALE....... i was wondering what was going on, headlight and tailight worked, rode it for a couple miles and shut it off and back on again it was still the same. so i pushed the button on the speedo and it did something different and in about twenty seconds everything was working again........ so if this happens to you, just hit the button
