[QUOTE="Fred W, post: 917450, member: 3828"] Bill, I'm sure Don will be along to report on this, but my recollection is that they determined that his "knocking" noise just before NERDS was from carbon buildup on the pistons. I think the "fix" was just running a bunch of Ring Free through it and the knocking went away. After that, he did run the bike a whole bunch of miles out to Vermont and back via the PNW, so it doesn't seem that it would be directly related, but I wonder if the apparent headgasket failure is related to all of that piston knocking on carbon that happened back then. PS - Sorry to hear about the head gasket, Don. Hopefully that is all it is. I guess the good news is that since you'll have that head off you can [I]really[/I] see how much carbon buildup remains. I forget now, did you (or whoever was working on the bike) ever scope the combustion chambers through the plug holes back then? [/QUOTE]
