I have a '99 K1200LT and right before winter the speedometer stopped working correctly. It started jumping around at steady speeds. Can anyone tell me what might be the problem and how I might remedy it?

It sounds like a broken wire by the rear wheels speed sensor. It was a common failure on the early model LT’s. It most likely broke by the wire clamp. I am not on my pc so I cannot provide a picture.

HTH. Click on the *Technical* drop down item, then click on troubleshooting, then electrical system, then on erratic speedo fix. When there, click on 'Dave Shealey' and that'll pull up the easy fix to a well known early year issue. Good luck.

Thanks for the tip. However I checked the speed sensor wire for possible breaks but couldn’t detect any, so I decided to replace it with a new one. Now the speedo doesn’t jump, but only goes to about 25 mph. The odometer seems to still work though. Any other suggestions?

Pull the sensor back out and see if the slotted ring in the final drive that she sensor reads has come loose in the final drive.

I was thinking the same thing, or at least to check it. As Scouter-50 said, remove the sensor and look down in from the top to see if this ring is still attached. you may need a good light and a mirror but you should be able to see if it has come loose. The attached pictures are what you are looking through and what you are looking at. This one is still attached.

Thanks for the tip. I'll give it a look. Not sure what to do if it has moved, though. If you know of a tech link on how to repair if needed, I would appreciate it. Thanks again guys.

Look over the procedure listed here . If the ring is loose you can safely open up the drive on the bike and clean the area and loctite the ring in place, then re-assemble the drive.
