Had my third customer, this morning, with a potentially violent "headshake" only when decelling from anything above 50mph. All three cases the same symptoms. 2010 and 2011 (today was the first 2011) FLTRSE, less than 3000 mi., one with stock windshield, two with Klok Werks. 4th, 5th or 6th gear, roll off throttle to slow down. As speedo reaches apx. 45mph, slight wobble begins and increases until apx. 35 mph, then quits. Found strg. head set at 3-4 full swings, adjusted to 1 1/4 swings. Bikes will still set up a headshake at same conditions, BUT only if hands are not on bars. Better, but I know there is still a geometry issue not addressed yet. No such irrepairable complaints from "Batwing" fairing owners, only fixed fairing bikes. Already investigated the more obvious/traditional points: tires, air psi, runout, alignment etc... Hard to believe in frame flex, but is the new frame TOO rigid? Does the "Batwing" fairing act as a spoiler to mask the condition?

I've seen this condition as far back as 2001. I can't come up with a solution until I understand the cause. ANY help? Anybody?
