Speedo not working

[mrhedges]

On my last long motorcycle tour last year my Speedo stopped working. I finally got around to fixing it last week when I had the front wheel off to put on a fresh tire and replace the bearings. When I had it apart it seemed that the speedo gear seized and stopped spinning. I replaced the gear with a used one, tested it by hand but after installing it, it still doesn't work. It seems when I spin the wheel the speedo cable does nothing. What engages the gear in the wheel? could that be messed up? Is that replaceable?

The end of the cable that engages the speedo drive at the wheel had a slot in it that engages a tab that comes out of the speedo drive. Then have to engage. the other end that goes into the back of the speedo is just that cable that's been hammered to a square shape and slips in to the drive in the back of the speedo housing. Cable could be broken. Easy to check. Unscrew cable at both ends. Pull the cable out of the sheath at the wheel end. Should be one continuous piece. If there's more than one piece that comes out of the sheath, you need a new cable.
