That was it. The sprocket nut. Got it put back together, torqued down, and the lock ring bent down. Took it for a ride and it works great. Haven't seen that gauge move before. It was nice. I put the "first" ten miles on the odometer since I've had it. Thanks for the help everyone!

It must have been messed up before, enough at least that someone took a hack saw to it and cut it up a alot. Here it is.



and here is a new one i found a picture of. Notice how much longer it is.



That looks like the problem. I guess i'll have to see if the shop has that tomorrow. I'll let you all know how that goes. Thanks.

The speedo sensor was fine. I ordered the spacer and it should be here later this week or early next. I'll throw that on there when i get it. Hope that works.

Not sure what the resistance should be but a service manual should tell you.
That lock washer is important yes, but what about that other washer? It's a pretty big washer...
As for testing the SS.The manual tells me i need power to test it like that, but it wants a little harness tool that makes it way easier. I can't tell if i'm ever doing it right. The guy at the dealership has the tool i'm assuming and is only gonna charge me like ten bucks. I'll just bring my pile of speed sensors down and have em check it out.

Here's a closer picture.



Before I get on to electrical I have noticed a couple things that are missing. The lock ring, that I hear about a lot on videos of people trying to replace their sprockets, but also a washer type thing. If you see here on this website.

If you look at part number 92200c, it doesn't seem that i have that part on my motorcycle. Could it be that without that washer and lock washer that perhaps the nut doesn't stick out far enough for the speed sensor to collect a signal? Any thoughts? I'm getting the speed sensor tested at the dealership on Monday, just to make absolutely sure it works, even though i've gone through 4 and they all seemed fine.

Can you post a pic of what you have setup as it may help us out a little bit. My money is you have the wrong sprocket nut on it and that is why it wont pick up the signal the ECU needs to send the pulse signal to the speedo head.
Here are the pictures. And that isn't rust, it's grime. And i do apologize for the filth.

Sounds hokey enough to work. I wish i could just talk to a kawasaki tech or something. I guess i'll just have to experiment a little bit.

jager62 Okay. I took a gander at the sprocket. No holes. So that got me wondering, and I called up the local motorcycle shop. They mentioned it could either read off of the sprocket or the sprocket nut. So I did a google search and on zx6r forums they show little marks on the sprocket nut that are meant for the hall sensor, which i'm assuming is another name for the speed sensor. So I gotta know, is it the sprocket or the nut that the speed sensor reads off of? I see sprockets all over with holes and some without. He did mention it could be backwards and there could be a strip with magnets in it on the sprocket that could do the signals. I'm really confused here! Even his dealer book didn't show what did the actual signaling for the speed sensor.

It's funny that you bring that web page up. I was just on there looking at that same diagram. So it's the hole drilled into it that makes the sensor work eh? Makes sense. I guess I'll just need to go and take a look at the sprocket when i get home to see if it has those holes. I've looked at it before, but it's been a while ago.

jager62 Do any of you have an example of what it should look like so that I could compare it with the one on it and see if it is incorrect or simply put on backwards.?
