Speedometer problem

2006 SMR 510, the speedo reads out varying speeds between 50-150 mph while I am idling in the pits
Anything in particualr to look for? I figure it must be the cable/wire I just put a new front tire on and my speedo wire goes down there near the banjo bolt for the brakes, so I'm thinking I must have screwed something up when I put the front wheel/brakes back on. Will post pics later. Thanks

thanks for the suggestion, I tried that no dice.
I made some more observations though. The high beam indicator stays on no matter what I do with the lights, and the display is flickering. I had the display flickering before and it was cause by a loose bolt in my stator. I repaired that months ago and the flickering stopped. So that will be the next thing I check. But would that cause the speedo to misread and the high beam indicator to stay on?

well that stator bolt backed out again, so hopefully that was causing all the symptoms
