engine sporadically "stuttering", tach goes crazy

I seem to have gotten a handle on all my other electrical gremlins bu tthis one is new: while riding yesterday, my bike started to sporadically, just for a second or so, 'hesitate' i.e. power loss, sluggish, tach going twitch-crazy, etc, and then run smoothly again. Didn't seem to do it at low rpms...any thoughts as to what might cause this? (beyond the obvious "loose connection"-I checked them)

Bars, grips and end caps

Lots of polishing!

Clean the safety switch on the stand. Spray with wd and work a bit. It cound also be the ignition switch, try wiggling the key when the problem accures. And also the coil connections.

I know someone had this problem before and we found out they had their bike key on a ring with a bunch of other keys. Seems that extra weight was making the ignition switch wonky.

Check the kill switch and it's wires too.
