I downsized from an Ultra to a 2013 Heritage and noticed when I'm running 70mph plus I have a lot of turbulence (movement) of the bike itself. I feel very little turbulence myself.
The bike seems smooth at lower speeds.
A good description would be the turbulence you feel when behind a simi truck, but there's nothing around me. I put dyna beads in the wheels because the weights kept coming off the rear wheel. I checked the spokes, air pressure, and all seems ok as far as I can tell.
Before I take it in, I was curious if anyone had any thoughts on this. Thanks

 

I run my 2010 Heritage at 80-85 on the highway and it's rock solid. I'm not sure I understand what you mean by "movement of the bike"?

 

No movement on my 08 Heritage, I usually cruise at 70-75 but even at high speeds it is rock solid.

 

Like I said, the wind turbulence you feel when around a Simi, but I feel it when it's calm and no traffic.

 

Don't want to insult anyone's intelligence, but are the axle nuts tight? Look for uneven tread wear on the tires. Sometimes when putting a new bike together, the dealerships rush and just plain miss stuff. I have to agree with everyone else, my Heritage cruises best in the 70's. Hope you get it fixed without the runaround at the dealer.

 

The hwy I ride back and forth to work has grooves cut in the asphalt for water. No issues with my heritage, but my last bike, suzuki, and my old sporty would follow them. Sometimes it would be quite disturbing how much the bike would move. If its not that or any of the above I'd take it back and tell em what's going on with it. It oughta be smooth as silk.

 

Pull the windshield off and see if anything changes.

 

No wind, no semi's, should be no problem. I get nothing but smooth and solid.

 

No problems on my Heritage either even over 80mph. It's a very stable bike unless it's really windy.
Check spokes, tire pressure, tread, are you bags weighted evenly?

 

My Heritage has a completely different personality without the shield. You might try taking it off and running 'er up to speed. Also, are there any types of wind deflectors on the front forks? These too, could change the attitude of the machine. Finally, as mentioned above, mechanical issues, tires, spokes, axle nuts (front and rear) could be contributing to the concern. Could it even be the dreaded "wobble"?
