hey all. I have an 1981 CX500C. My speedo needle was bouncing like crazy at higher rpms and running about 7-10 mph lower than actual speed. I just replaced the oem cable with an aftermarket one and immediately noticed the new one was a little longer. it also doesn't seem to be as snug at the wheel mount. now, the speedometer works great! except, the cable is very noisy, a loud winding noise. will this go away? or is it because the length is different? any help is appreciated

Did you lube it? Three-n-one oil or similar dripped down, inside the cable housing from the top.

138707-001 - $15 + shipping from bikebandit.com, a bit over $20 + tax from your local dealer.



I bought the exact cable about a month ago from the dealer, came pre-lubed inside a nice Honda bag and had all the extra outer sheathing that most aftermarket ones I've seen don't have. OEM part, I'm sure it will fit perfectly.

i went to local dealer today. purchased oem cable. still loud noise from gauge upon installation. i isolated the noise to the gauge end by lifting wheel while on center stand and moving the wheel. didnt have this problem with the old cable. so its a bit of a mystery. i wonder if the gauge is bad...

i now have loosened the connection at the speedometer gauge slightly, instead of having it real snug, and the noise is gone. weird. can't figure that out at all.

If you unhook at the speedo side and no more noise then it has to be in it. Could be the input shaft that receives the cable is worn to the point that the cable is slipping in there? Take a strong flashlight and have a look at that. If worn, your only alternative asides from replacing it is a single wrap of that aluminum foil tape they sell for duct work on the cable's output square end to slightly enlarge it.



You haven't updated your profile such that it has a location as if you're in a cold location that makes driving the things a bit harder in winter, also add a small signature line with the year/model.



I'd hate to have to change my speedo as the mileage would be off. I may have one spare but I'm always on the lookout for another, mine is the 120 mph version and belongs on the bike as they'll go over 100, you've got the 85 mph one that's relatively easy to find.
