I got it from Captain Kyle who had run it in the high 10's in the 1/4-mile. Low 20K miles, he said. Since it was out of the bike, I wanted to see how it looked, so it's been partially-torn-down. I spent today doing the valves the old-fashioned way: on the bench grinder/wire wheel. They're done, now to lap them.
It appeared that the engine had never been apart. Don't know that for sure. The intakes had some thicker deposits on them but the exhausts are harder to clean. Wish I had a glass-bead cabinet. And a lift, and a MIG or TIG. But, next-best, have friends who have these. The local Yamaha dealer should have the order of replacement gaskets & miscellaneous parts to reassemble the engine by the first of the week. Then, media-blast it, paint it and re-install it.
