Speedo

[Kingo]

Hi there
I recently picked up my Fat-Boy from the mechanic and the speedo is not working correctly. It goes up to 20mph back to zero up to 20 back to zero.I don't think it's busted just not lined up right.Any advice would be greatly appreciated

Check/replace the speed sensor on the trans. More than likely the problem.

sitting still?, just after you turn the key on?, riding down the road at 20?, all the time?, some of the time??????
