I just picked up my 13 FLTRU from the dealer after having the 1,000 mile service completed. When I dropped it off, I told them about the wobble. Of course the service writer acted like he had never heard of such a thing. But, when I picked it up the work order said they had adjusted the steering head bearing and checked fall away. I looked at the invoice and realized they were trying to charge me for correcting this and told the service writer there was no way I was paying for it when the bike is brand new and under warranty. He went into the service manager's office for a moment, came back and promptly removed that charge from the bill.
On the ride home I tested it several times and the wobble is gone. So, it is a minor problem that is easily corrected. But, I read through the above referenced thread and it seems that many dealers are charging to fix it. Stand your ground and tell the dealer you are not paying to correct a defect on a new bike under warranty. I would guess that many dealers put the charge on the bill because many owners will just pay it without question, but if you complain they will likely remove the charge.
