Oh thanks doc.
Ryan maybe its time to deal with real problems - plus how do you know "think" that its 50? I mean depending on the road, weather, surrondings etc there's no way you can "just know". But in general speedos are made to show higher speed than actual, this is to compensate for their tendency to show lower speed as the speedo gets older and looses magnetic qualities.
OK, so in this new world of Electronic Speedo Senders, why the hell are the damn things out. Some of the car magazines when reviewing new cars had indicated/actual readings from the speedo and they were out by up to 10%
EDIT.......... The voltage regulator on the back of the speedo (inclubman's anyway) are the little rectangular metal box. This comes straight off the PCB. If you get the case off(a real PITA), then you will see an armature like ingnition points. The contacts in here are what stuff up. There is an adjustment screw on there, but I would advise
NOT messing with it, unless you really want to.
