Speedo Questions
Surely somebody has seen this. I can be going along just fine (even though my speedo is 10 mph off) and all of a sudden my speedo will fluctuate up and down from 50 to 90 quickly. When this happens, I can hear a very faint sound. It sounds kinda like a buzz, but it might be the cable vibrating or something. Anyway, then it stops and settles back to being 10 mph off. I figure the reason it's off is due to gear and tire sizes. This leads to my next question. Does anyone know where to get new gears for the speedo? Preferrably the driven gear.
Thanks in advance.

If I can get the fluctuation out of it, I can deal with the 10mph off. Glad someone else had this problem. Now to get someone to point us in the right direction. Anyone???

Mine also sticks at 60 mph then eventually will jump up to the proper speed once i get going around 70 mph or so.

Could be a cable binding then letting go whipping the needle up or possibly the head itself. Inside the head a magnet spins inside a cup which is balanced with a spring, if the mag touches the cup it will whip the needle up also.

I purchased new gears, housing, and clip from these guys. This will get your 10 mph correction.
