My 08 Heritage has a wobble when I get around 40MPH or so. That's when it's most pronounced, but I can feel it at higher speeds also. The dealer tried changing the tire, then the rim. It seemed better for a while, but now it's back. I have sort of checked to make sure the spokes were all tight, but I don't have a spoke wrench. I tapped on each spoke with a small crescent wrench and got a nice tone out of each one. Any ideas of what I could check next? Any help would be greatly appreciated.
