1100GS Speedometer

[Smallwheelsgood]

The speedometer on my recently purchased 99 1100GS doesn't work. I've disconnected the cable at the axle to find two things: firstly, the drive peg rotates when the wheel is rotated, but the action appears notchy and the peg appears to be able to be stopped with finger pressure. Secondly, I spun the slotted end of the cable with a drill, in both directions and at low and high speed with no reaction from the speedo. Any thoughts or suggestions before I start dismantling things to get to the back of the speedo? Thanks

Nylon drive gear may have stripped its a remove the front axle and drop the drive out to examine it better (Wheel can stay in you just need to slip callipers off and pull the axle across a 1/3rd of the way

(N.B. use a tie strap between the centre stand lower bar and say the exhaust (cold obviously) to prevent accidental knocking forward off the stand

Secondly, I spun the slotted end of the cable with a drill, in both directions and at low and high speed with no reaction from the speedo.

Pull the inner if its good you will get the whole length if as I suspect its broken you will maybe get 2 or 3 inches
