Got to the speedo cable tonight and lubed that up. Couldn't loosen the screw at the hub so I pulled the plastic under the dash and was able to easily access it there. Lubed it up, did a few laps around the block and it sounds like it's quieted down quite a bit. I'll ride it to work tomorrow and see if the noise is gone. I'm almost certain that was the culprit.
Thanks for the heads up Wentwest, saved me a ton of time trying to figure it out.
