    I searched and couldn't find an answer, so I apologize if this has already been asked (which I am sure it has).

    I recently picked up another KLR. The speedometer is acting all funny. At first, it looked completely dead, then after a few miles it would start working and appeared to work normal. Now, it won't work for the first mile or so, but then starts working only up to about 10mph or so (no matter how fast I go, it stays at that speed).

    I have checked both sides of the cable, and everything seems to be seated correctly, and the insides turn without trouble. I left the top connection unplugged so I could watch it while riding, and it seems to turn freely (albeit slower than I would expect for any given speed).

    Any ideas what might be wrong, or how I can better trouble shoot it?

    Thanks.

    Its most likley lack of lubrication inside the cable. Pull the inner cable out of the casing, slather on some light grease and stick it all back together. You could also lube up the speedo drive unit at the hub. that should fix the problem. If it is the speedo I would suggest ebay for a replacment as the stock kawi unit is going to be pricey. some guys have used a bicycle electronic unit or an aftermarket speedo like the trail vapour

    Is the drive washer (called the receiver) in the speedometer drive housing flat? You'll have to remove your wheel to check it. Sometimes the two tangs get bent when the speedometer drive is not put on the hub correctly. Hammer it flat if it's not. Then make sure the tangs line up with hub and speedometer gear properly.

    One winter mine got gummed up with spider webs, down where the needle slides into the cup that is spun by the cable to create the forces that move the needle.

    Check what JV suggested. This happens fairly often when front wheels are removed from KLR's and not assembled quite correctly.

    Is the odometer accurate? It is in the drive if it acts the same way. It is in the panel if it doesn't.

    No, the odometer acts the same way; ie it reads that I am moving but at a much slower rate than I actually am.

    So, by saying it is in the drive, are you saying the cable, or down by the wheel hub?

    Your front hub is jacked up.

    Take it apart and you'll see that the tangs on part #41064 don't line up with the slots on the hub, I guarantee it.

    It has to be coming from the source, which is the hub. Typically the cable works or doesn't work. If it is dry or bent you should hear noise, but it is a somewhat solid piece so if it turns on one end it will turn on the other.

    Take the hub off like ca stu says and make sure everything is put together right. I also bet you will find that is the problem.

    Thanks guys. I was going to take it off tonight, but I don't have a cotter pin to replace it with, so I will have a look tomorrow after I can get to the store.

    I'll let you know what I find.

    Ok, so I got the tire off to have a look, and this is what I see.

    I don't know, but it looks like everything is lined up to me??

    What do you all think?

    Take the tanged washer out and beat it flat. Then put it back together.

    The inner tangs engage the gear like it is doing now but the outer tangs have to fit in to the little slots on the hub. It has to be flat in order to do that.

    You were right. Worked like a charm.

    Thanks a lot for the help, I'm sure this question is brought up repeatedly. Either way, I never would have figured that out on my own.

    You gotta love this community!!!
