These speedos are terrible. I have a Speedmaster and an America and both of mine have done what yours is doing. Replaced them and the Speedmaster is doing it again already. Go down the road sometimes all is well, sometimes I'mm doing 120 mph on my street. It's the speedometer itself. I'm getting ready to do an aceweel speedometer since my gas tank is custom so I have no neutral/ high beam/ directional/ oil pressure lights anyway. I have lots of plans and even more bikes.
