Ok, I'm stumped.

2000 R1150GS

I have noticed at slow speeds 30 and below the bars are wobbling left to right when hands released (I know do not release hands), but I'm starting to get annoyed by this.

Things I have ruled out so far

Wheel out of balance ( had it relabalnced just in case)
Tire pressure (good)
Sticking brakes (brake drag on front is a little more than I would like)
Steering head bearing (good)
Wheel bearings seem ok (no noise and very smooth)
Cleaned out calipers (anyway)
Bled air out of fork tubes
Front shock/strut only has 5K miles on it

Anyone else experience this issue? What next to look for?
