Vibration during decel
I had my 2019 Heritage serviced at 10k and had a set of Metzler CruiseTecs tires installed. Ever since the service, I get a vibration when I'm decelerating. Its pretty consistent that it occurs between 30 down to 20 mph. The vibration occurs with the clutch engaged as well as when the clutch is disengage, so I don't think it is the motor. The vibration feels more pronounced when I am on the brakes, but I can still feel it when I'm just coasting. The vibration feels like running over rumble strips but not as serve and at a higher frequency. I brought my bike back to the dealer to check it out and they said the couldn't feel it (total BS, they just didn't want to deal with it) I asked them to dbl check the belt tension, and the said it was fine. The belt is riding right along the outer edge of the pulley. Since this time I have put about a 1000 miles on the bike and vibration is still there. It doesn't seem to effect the performance, however, it is annoying.
I'm thinking it could be one of the following:
balancing of the new tires
the tires in general
the belt rubbing the pulley
warped brake rotor
I'm wondering if anyone has some ideas on what could be going on, or things to try for troubleshooting.
Thanks!!

Yeah, I went back once and they said they didn't notice anything. I don't have a lot of confidence in the Service dept, I think they lost most of the mechanics due to covid lay-offs. I'm planning to get some work done on my bike serviced in a few weeks at another shop, I'm going to ask the also if they would take a look at it.
It very well could just be the tires, but I'm not sure.

The fact that "they lost most of the mechanics" has me wondering who does their tire changes. They very well could have damaged a brake rotor if they had some brain dead nincompoop changing tires.
You said it's more pronounced when you're on the brakes, so that's why I thought brake rotors.
Here's a video showing a quick and easy way to check if you don't have a dial indicator.

Good luck with dealing with service.

I have to think if it were brake related it wouldn't be confined to deceleration from 30 to 20. It would be all the time. I think you feel it more when on the brakes (both brakes or just one?) because whatever is causing it is transmitting the vibration into the brake system.

I checked the front and rear disk runout using thorn method. Both rotors looked fine.
I also checked my belt tension and it measured about 5/8 of deflection, which I think is fine. The belt is still all the way left (when sitting on the facing forward) against the side of the pulley lip.
So far everything is checking out. Maybe its just the tires or how they balanced them.
