A while back the speedometer on my '73 T140V stopped working, and it turned out that the cable had gotten crimped severely. Picked up a new cable and installed it, but the speedo still doesn't work. It looks like the reason lies in the drive gearbox. I detached the cable from the drive and connected it to a drill, and the cable/speedo work fine. I sprayed some WD-40 inside to hopefully clean out any gunk, and greased the gearbox at the nipple on the bottom. Still nothing. Is it possible that when the old cable was crimped it burned out the gears because the cable wouldn't turn?
Along the same lines; I also replaced the tach cable at the same time because the outer casing on it had cracked. The needle bounces around a lot (it did with the old cable, too). I checked the tach, and using the drill the gauge runs smooth--no bouncing. I opened up the tach drive and cleaned out the gears, but it still bounces while riding.
The bike is pretty much my daily rider, so the speedometer is pretty important. Any suggestions for either problem? Am I overlooking something?
Thanks,
Joseph
