So far everything is checking out. Maybe it’s just the tires or how they balanced them.

Or maybe how they didn’t balance them.....properly

When I get tires installed I R&R the wheels myself and take them in to have them mounted and balanced. I always check them on my static balancer before installing the wheels. So far the place I take them (a metric bike shop) has always been right on.

This is probably irrelevant because I have a dyna rather than an M8, but: my bike had the same symptoms and, in my case, a new head bearing resolved the issue.

Do you mean a slight wiggle/shimmy/shake you feel in the bars? If so, its the tire. It started after they put it on, right?

That something the dealer mention and that they checked it.

The vibration is more thru the pegs than the handle bars. It is similar to driving over rumble strips.
