Last fall I had all my steeper motors replace. Today I'm going 80 mph at 1000rpm. So what that's tell me, bad motor on speedometer. When it is shut off needle sweeps down to bottom center. Can someone tell me what their speed is at 1k ,1.5k, 2k &2.5k on their tach. I think I know pretty close by guessing. Don't want to get a ticket going to the Valley.
