[QUOTE="Aasland, post: 1130135, member: 14773"] Good point. Also, the lack of any .. and I mean ANY ... carbon in the intake tracts seem to make the case that they do seal well. But I would still like to get that crud off the valves. That's the conclusion I reached yesterday too - more so considering that we have 3-4 weeks until weather lets me ride anyway. Yep. So I pulled the head last night - took maybe 15 minutes, and placed an order for the new gasket and bolts ($50). There was a bit of carbon buildup in all the cylinders, but I could still see the crosshatchings. Based on how clean this engine is for being seven years old with 24k on it ... and it's clean in places that are hard to clean ... and the accident occurred in December .. this engine hasn't seen much use at all and probably suffered from sitting around in humid environments (DFW, TX) and running on old gas. The spark plugs were in pretty bad shape, they were probably the original. Cylinder #4 had a light tan coating to it. Maybe it needed a TBS? Who knows ... after tearing this machine apart, I'm tempted to dig into my 98k mill and see what that looks like too. [/QUOTE]
