on an old bike, and at the same time I re-profiled the contact faces on the plastic bit. You'll need to remove the front wheel to check all of the above (hope you've got a centre stand). Sorry, I should have mentioned that I have already made that adjustment and can see that the speedo drive works perfectly by disconnecting the cable and spinning the front wheel. My gut feeling is that either the inner cable is slightly too short or something inside the speedo itself isn't right. Anyone know if it's possible to extend the inner able somehow, or shorten the outer cable by just a few mm to have the same effect? Re: Speedo cable appears to be too short! I've done the same, the cable worked when disconnected from the dial but not when it was all connected up properly. As said above it was the metal tangs in the wheel, they had been very slightly bent over, probably when refitting the wheel on a previous occasion. They work when there is no pressure but slip when the drag of the clocks is added. I was lucky, had a spare wheel to compare and see the difference and bent the tangs back out, problem resolved. 3 Africa Twins/280,000 miles. If it's happened to one of mine, it's gonna happen to one of yours.....eventually. 1 Varadero/28,000 miles ridden (of 51,000 miles on the bike), it's all still new to me!
