Rough feeling on deceleration

Today I reduced my speed from 60mph and there is a new feeling. Whenever decelerating above 55 there is a rough feeling coming from low down. It's hard to tell what it is
I removed the variator cover and everything looked ok. The belt has been recently replaced. Accelerating is fine, it just as soon as you reduce throttle it feels like a vibrating rubbing feeling.

by you you
If it happed just after the belt was replaced it’s likely the two things are connected...

The belt has been on there 2000 miles.
Last week when I pressed the start button it failed to turn over twice and then died after start up. It has been fine since then.

I removed the variator casing again. Belt, weights are all fine. Clutch bell is good, no signs of anything broken.
I took the scooter for a ride and the vibrations come at around 30 mph whether accelerating or decelerating. I'm wondering if it's the cam chain tensioner.

Try putting it up on the stand and see when (rpm) this vibration occurs at. See if its consistent all the time and look and listen for any abnormalities . Start there.

Remove the sandpaper from the seat cover. It's like the dog said when he sat on 100 grit .... "Rough !"

How many miles on the bike? Maybe the clutch pulleys are hanging and causing extra belt vibrations? Disassemble Clutch assembly and inspect the slide and pin the pulleys ride on.

Update on this issue. I had put the Pcx on the centerstand and accelerated but I couldn't replicate the fault.
The clutch pulleys looked fine. I ordered a replacement driven face with new wheel bearings and the issue is still there.
The scooter will ride fine at town speeds. Once I get about 55mph and let off the throttle completely there is a vibrating on deceleration regardless of the speed. Once I come to a stop and then set off it is gone. It only begins once you get up to a high speed.
I want to say it feels like the belt but the belt looks fine and is properly installed, the boss is free from dirt or anything.
