On the carb selection front, I've had a bit of a setback. I was planning to use a pair of Keihin CRS carbs in 37 mm size, which I have left over from the single racing days, but they aren't going to fit. I'm using a pair of Steve Maney's CNC machined manifolds that are matched to the heads, and they are too long for the CRS carbs. I could relocate the throttle drum to clear the tank, but the carbs still interfere with the gusset at the top of the frame. I could make them fit if I made some shorter manifolds, but I don't want to do that. It would be hard to match new manifolds to the head with the bike in the frame, and I don't want to pull it out again. I have a set of 36 mm Amals that I could fit, but I really like the light throttle pull on the Japanese push-pull carbs. Before anyone jumps on me for not being manly enough to handle a stiff throttle, let me pre-empt them by explaining that I've had surgery on both hands and only have about 60% normal strength in them, and at 74 years of age, I now get to add arthritis to my blessings. A light throttle pull is pretty much essential if I want to ride more than a few miles without cramps.
I've checked the other carbs I have, and neither the 41 mm FCRs or the 34 mm Mikuni flat slides will clear the frame. I think the 35 mm FCRs might be the answer, but that means buying new carbs. I've been really trying to use up stuff I already have. I have some other Mikuni carbs, but they won't fit without angled manifolds, and I don't want to do that, so I think I'm stuck with buying the FCRs. Always more decisions to make.
On the positive side, I got the mag wheels back from the inspection shop, and they are free from cracks. And I have the cert to prove it! I need to touch up the conversion coating, and then paint with a good two part paint (gold), and I'll be ready for tires. Still looking on that front. I've used the Avon Roadriders for several years now, and might go with them, but I'm thinking about trying out the new Continental Go line.
