I was reading this last week and I had to find it again & post on it... My bro-in-law has a 09 RG and he had the same unstablity feel sometimes just as you are discribing. He just brought his bike in for service and had the front tire changed (after calling HD to get the dealer to do it) as they were not willing to change it, he tried on the last service visit... anyways he picked up his bike on sat and we went riding... he said once we were done that the wobble was gone... front end felt good, no more concerns... he had the 407 tire on it and they changed it to the new 408 tire.... so check into this also for your bike....
