Cruising along at 60mph in 5th gear the speedometer is showing 2 cyl for a second then going back to showing speed. The engine does not miss, the light is steady. What would cause this?
Thanks
I’d start by making sure you dont have a loose connection to the back of the speedo. Take the back plate off the speedo. Push the pin connector back in place and if needed, use a piece of foam rubber to put pressure on the connector when you re-install the back plate.
Insure the conection is good to your front cylinder wire comming from your coil, the speedo gets RPM input and can make it intermittent. Just noting one of my discoveries. 😉 Chop of OH10
Thanks for the suggestions I pulled the back off the speedo and the connectors were not real tight. I cleaned the connectors and re seated them, also re seated the wire going into the box as it was pulling the connectors apart. I think it fixed it, I had the coil off and lengthened the wires so they were not so tight. I will trace that front cyl wire next time I have the tank off and make sure it is all good. Thanks for the heads up on that.
