so i have an intermittant speedo issue since changing front ends on bike, I went thru the old threads and it appears as tho maybe a grounding issue. but before I start ripping into it,

speedo works on start, till i get to speed and it goes out, hit the clutch and it comes back on, have looked at the wiring I had to do and can find nothing to be suspect, now assuming this is a grounding issue can it be any ground that causes this? IE I installed led's and I know there is a ground issue there at the switch, is this enough to so somethign to the speedo, or should I concentrate on speedo connections only?
