Another Lesson In Humility.
The best supervisor I ever had used to say "Every now and then we need a lesson in humility". Here is mine, experienced over the past three weeks. In that period I have found: a bent valve; a tach that did not seem to work; a non-charging electrical system; and, odd problems with jetting.
The good parts: I have not found one leak in the new oiling system and the many lines. And the brake system seems good. Things are fitting in nicely.
First the bent valve: Low compression in a cylinder forced me to do a leakdown test. Hear a loud WOOOOOOSH from the exhaust valve. It was bent, and I have no idea when or how this happened; it was new. Guess which cylinder is was --- of course, the vertical! So, out comes the engine and apart comes most of the bike --- it seems.

In goes a new valve and everything is back together. 150+ lbs compression on both cylinders now. And it wants to start, sorta. Check the timing and decided it was advanced a bit, and off comes the exhaust and the alt cover and that gets changed. Started with 140H/145V main jets. LEAN! Red hot exhaust, especially the H cylinders. At this point I am now at 185H/175V; higher that I could ever expect, and backwards from the usual setups. And increased the atomizer to 268 from 265. H cylinder still wants more. But, it starts, runs fine, and kinda idles. No more red-hot exhaust, with pipe temps at 400 to 550F (according to my Harbor Freight pilot-blinding lazer light) in the garage with a fan on the engine. OK. Would appreciate thoughts and comments about such high jetting.
During this period I noticed that the tach was not taching. Wobbled a bit, and then nothing. Tried more than one combo of cables and 90 degree drives and tachs. "Damned after-market stuff", I said, and can't remember where I got it from. Touched the H cam wheel and noticed that the plate behind the cog was loose a bit (my bad?). Tightened the locking nut (again?), and now I have some RPMS! Good to go.
Then it is time to check the voltage regulator, and it was AWOL. Getting nothing. Switched to a used modern 2-phase regulator (1994-1997?) from the NEW older 2-phase version (Paso, 750 Sport and SS), and got 14.4+/-. Bingo, we got juice. I am going to post something in the TT Technical section about this, because this is the second time this has happened, and I am over-supplied with the wrong version it seems.
Finally, three weeks after, two weeks later than planned, I can start on painting the bodywork.
