Well I disassembled the device. The internal assembly looks ok, more or less. The strange thing is that when I turn the spindle, the dial only moves when the device is upside down, or tilted to the side. When the dial face is towards me, the rotation of the spindle does not move the dial at all. Any...

Re: R51/3 - 1952: Which speedometer should I order?

Another thing: Since I'm not in a hurry, and I have tools and time, I'll try to disassemble the speedometer and see what the problem is with it (I remember it was moving but frantically, so maybe it's fine and all the problem was with the speedo cable, which is new now). Does anyone have any idea ho...

The solo rear end ratio for r51/3 should be 39.9 and speedo for km should be w.95 and mph 1.52 according to the chart Kurt posted

Re: R51/3 - 1952: Which speedometer should I order?

Evening Kurt, Thank you.
Does it means I need to know the final drive ratio on my bike?
I think that my 51/3 went through a change on that as I discovered when rebuilding my final drive and asking here some question. Is it the number that is stamped on the main big gear?
