Speedo Problem

This morning while riding the speedometer needle started shaking around a lot but still registering speed. Then after a few minutes it stopped moving almost entirely, and now just shudders around at the bottom of the gauge. I took off the front visor and checked the shaft, but from the outside it looks fine. It also seems fine at the wheel. Anyone have any ideas before I start taking everything apart?

plastic/nylon(?) speedo drive gears at the hub.

Would these nylon splines conk out all of a sudden? I've put lots of miles on the bike, and even rode it last night without a hiccup from the speedometer. Granted, it is all the original components, so I guess age could also have something to do with it. But last night it was fine and 10 hours later it doesn't work at all.

The coiled metal drive spring breaks as well. Take the speedo cable off and check the inner.

I think its the way the rubber mounted clocks vibrate at certain revs, they move quite a lot.
I gave up and just mounted a little digital speedo.

This one turned up on our local CL. I'd be more interested if it were still stock. Also, his price has increased by $50 since the ad ran two weeks ago. They must be getting rarer.

I took off the speedo cable and when I push the bike forward, it doesn't spin. I assume the problem is with the gear at the wheel. Thanks for the help everyone!

That bike looks pretty good from the pics. The seat doesn't look ripped or torn, both exhausts are there, and it looks like those are the original fork boots. Maybe it has pretty low miles on it. I wish I had the time and money I'd love to buy it and make it look brand new!

Don't assume that, check the cable the inner slides out easily and available as a separate part.
Worth checking before you buy a new gear.

Rear fender brace -- '88 NX650 (US)

My rear fender brace has seen better days. I am mending it, and adding some reinforcements, but I need to replace the end plate that bolts to the back of the mud flap (license plate?) There is a hole where the grommet and bolt go through, but mine is so mangled that I cant tell if the hole was round, oval or what. Anyone out there able to provide dimensions on this hole so that I can fab the new plate?

I believe I know what you're referring to. I recently replaced the entire frame underneath the rear fender. I ordered the frame new since mine rusted through. I'm pretty sure the hole on the end plate was oval, but it seemed unnecessary.

Just want to see if I am on the right track, I rejetted the carb, seems to run just fine on the main jet but when I am going 35 or slower it stumbles, cuts out , if I use the choke it smooths out. I'm guessing i need to go up on the slow jet. the screw is turned out 1-1/2 turns

I am enjoying this bike so far

yet another problem...

Well, the bike is running a little bit better. I put some SeaFoam in it the past few tanks, and it has helped.

However, now the throttle doesn't snap back all the way when released. Any ideas how to fix this, and is it an easy fix to do?

Edit:
I just went and took a look at it. After playing with it, it went back to how it used to be, goes back slowly. I found a bug jammed in between grip and the switch housing.
