So I removed the battery and brought it to the shop to get another. I thought it was bad but it wasnt, a wire was just not connected right. So, After I found the wire and reconnected and put the tank back on....I fired her up. Now the speedo is putting out some wacky display almost like its a tachometer. its spits out numbers between 0 and 189 and fluctuated between these numbers rapidly. It runs good. What the deal? Does the computer work in a weird way with no battery? All I did was button the thing back up...didnt mess with anything. HELP!!
