I could check all those but problem should still be there when I remove tour pack...but it is not. I was actually wondering if wind resistance against tour pack could be the issue because king pack is large.
Actually the problem may still be there to a lesser extent when you don't have the T-P installed, and the addition of the TP just aggravates the condition. The items hd-dude listed are all known areas of concern on the earlier frame design bikes, which had problems with wobbles for as long as I can remember. There are others on the site, like Twolanerider, who have run a King T-P on a 2005 SEEG successfully, so I doubt it's just a concern because of the TP. Steering head lubrication and adjustment, front
and rear powertrain mounts, and alignment really need to be checked out.
