I pulled mine and inspected yesterday without changing it out, just from lack of planning more than anything. I know that it's supple and there are no cracks whatsoever so will surely be good for another 50-hour season

I did order Densos finally. My idle's been a touch mortal since pulling the fuel tank back in 2003. Never really annoying, and still really smooth, but not the velvet I remember from those first few months. Oh well, 330 hours isn't quite the advertised 1000, but it's still very acceptably performing.
Also...the serpentine belt is still supple, no cracks, chips, or really any obvious signs of wear at all. I've threatened to buy one to have as a spare, and probably should before Capt. runs out of parts.
