Wish I had a good story, but I do have a happy ending.
1.) Got back in and double-checked the valve clearances to make sure I hadn't done anything wacky there. Didn't really want to take that cover off again, but I didn't want to wonder about it and had to do it while the engine was cold.
2.) While I was pulling the tank off, I noticed the blue lining of the main fuel line was slightly separated and munched. It's a long shot, but it's possible that could have gotten flipped inside and restricted fuel flow from the tank. I don't know for sure because...
3.) ...next I hooked up my extension hose, put the tank where the seat goes, and fired her up. She already seemed to be running better. Sound-wise it was similar to before the valve adjust, but with my limited time, I didn't take the time to reassemble and ride to verify that there was power. I just let her warm up at 1800 rpm or so then hooked up my brandy new Carbtune.
4.) Then set mixtures, and synced. That #2 nut is a bear, even with the special tool! Any tips on how to make that easier? The sync was pretty off, according to the gauge, and I eventually brought it into line once I finished wrestling with that #2 linkage.
5.) Result were good. Much smoother idle. Sounded good at higher rpms. I just got back from my test ride, and I've got power I forgot I'd lost over the last year. Still not perfect - I've got minor hesitation just off idle and the power band seems a little narrow - not really kicking in until 6500-7000k rpm.
But, vibration is reduced at all rpm's (soooo much smoother, and I can see in my mirrors!), she really pulls again, and I'm not going to worry about the fine tuning until I get the rest of the shims I need. Then we'll do all this again, though hopefully without the "hiccup" in the middle.
