Odd noise from parked Kingpin
A couple days after I got my 2005 Kingpin home last week, I heard it make a funny high-pitched whine for a few seconds a couple of minutes after I had parked it. I assumed it was pressure releasing from somewhere as it was cooling. Didn't think much of it until I walked into the garage a day later and heard it again, nearly 24 hours after parking it. It's continued every so often since. The noise itself sounds a little like Mr. Bill (you remember Mr. Bill, right?) going "Noooooooooo..."
Any ideas what it might be?
