2023 XTX LE
Just got a new XTX-LE. After riding it for the first 50 miles yesterday when I turned it off it was making a bubbling/gurgling sound from the coolant side of the sled..is this normal?
 

YES.. Try letting it idle a minute before shutting it down after long hard pulls or long runs 80+ mph.. Another thing you can do it wait five minutes after you shut it down and restart the sled and idle it a minute or so and it will recirculate and cool it some also..
 
Please make very SURE ALL there isn't any air in system! These 998s are very sensitive to ANY air in system.
I had the same bubbling sound on my 20 but haven’t noticed it the last few years, wonder if that was air that made its way out of the system
