sudden increase in speed

Postby m2102 » Sat Apr 13, 2013 9:13 pm



coming home from work tonight on the interstate, I was rolling along in cruise running 70 mph. I "felt"something a jerk or something and looked down at speedo and it was increasing mphs'. gained about 5 mph and backed off to what I was set at. it just went up then down just as quick. anybody ever experience this increase then level back out? only did this once. looking for ideas on what could have caused this. thanks in advance.

I have had problems with the cruise changing speeds on two different 89 wings, most of the time it starts accelerating on it's own and I disengage the cruise. I don't know how fast it wold have gone. The fix was to change the speedometer cable. I just replaced the whole cable assembly, you can buy just the inner cable, but the whole thing is like 20 bucks.

Take a close look at your speedo needle and if it's 'twitching' at all, it's most likely the speedo cable (*usually) binding up inside the sheath. Replace the whole speedo cable and it will smooth out and so will your CC. As a yearly maintenance item, disconnect the speedo cable from the speedo sending unit on the front axle and remove inner cable. Wipe it down clean, inspecting the cable for any fraying of the cable before lubing it with some oil/graphite and reinstall it inside the protective sheath.

* It can sometimes also be a dry/dirty speedo sending unit located on the front axle that is starting to strip off the plastic gears, in which case it will need to be replaced. Best to clean, inspect and repack with some quality wheel bearing grease every time the front wheel is removed.
