Vibrations in seats

[Balquin]

So I just had my seats redone at Mean City Cycles and they are definitely more cushy. Was noticing I had more vibration in the seats and that is what causing discomfort now. Started to think maybe the engine mounts may be suspect so I started to do some thread searches. Came across the damper might be a suspect as well. It's an 08 with 11500 miles on it. Could the damper actually be in need of a rebuild? I'll probably go thru the process of checking the engine mount torques to eliminate those.
Really want to be able to take longer rides, but with my backside going numb from the vibration it's getting discouraging. I knew v-twins have there normal vibration, but coming thru the seats like that can't be normal. Any other suggestions would greatly be appreciated. Thanks!
