High Idle question 1999 Grand Touring 500

The above sled has no choke lever. It is liquid cooled.
When cold I have to pump the primer to keep it running and blip the throttle to rev it up. I keep this combination up for a couple of minutes until warm.

Once it is warm it runs great. Then when I slow down it Idles at 3200 rpm.

If I blip the throttle it revs up but falls back to 3200 rpm.

If I shut it down and start it back up with the key it starts fine and idles at 2000rpm. If I touch the throttle its back up to 3200!

Anyone have a solution to this. I am thinking of replacing the carb to engine boots first before I even think about carb adjustments.
