No and Yes
I've never had any speedometer problems at all. Matter of fact, I don't recall if anyone has ever mentioned it before........but then I can't remember if I'm awake yet!
As to the fuel light.......a lot of people have erroneous readings. Mine used to come on with 3 to 3.5 gallons of fuel still in the tank. 2 seperate times the mechanic reset it but to no avail. 3rd time we got Triumph to sent a whole new unit to be installed. Still comes on with about 2 gallons left but I can live with that.
