Normal Speedometer Behavior?

[nychayabusa]

I can't remember if my 02 did this but I noticed since I got my 03 when I pull the clutch in the speedo needle will go down to 0 MPH but when the clutch goes back out the needle will catch back up the proper MPH.

I just saw a video of a busa and the speedo stays at the proper MPH while he shifts.

Something to worry about?

Never heard of this either so hopefully someone with experience will chime in.

I've never seen that or heard of it. The speedometer pickup and gauge are independent of the clutch.

Just doesn't seem like something I would worry about as long as that's all it's doing.

Wow now I'm pretty worried about this since no one has a clue. The bike is bone stock - not an aftermarket piece on it.

Okay, I just checked the wiring diagram for the 02 and it does look like the clutch and speed sensor shares a wire. I figured it to be a ground wire that is shared but maybe if there's a bad connection, wire, etc some where along the wire it could be causing the problem. ???

Here's the wiring diagram:

The pickup for the speedo is situated on the same sprocket cover that work the cluch rod I guess that the cover is loose or cracked or the speed pickup is loose also check the front sprocket
Good luck hunting for the gremlin and don't forget to post the solution when it is fixed
