Thanks for the input.

A miracle happened. I put on the new gas cap and the carb now responds to air flow adjustment (just a little... nothing dramatic). At 1 1/4 turns the idle smoothes out and the bike sounds great. That's with the Minton jets with the exception of a little leaner main. I didn't swap back to the bigger main jet.
&nbsp\\;
I took the bike from Boise (2400 ft.) to the top of Bogus Basin (7000 ft.) and the thing was burblin rich. Okay, I can live with that because I might also head for the Oregon coast where the bike will be a little lean. Overall, it runs great. I can live with 32 mpg into a 30 mile headwind or 43 in calm conditions. Not sure the batwing will allow much better than that.

I'll have to investigate the HQ build though. The jets seem huge... but maybe you're closer to sea level.

Thanks again for the chat.
Much appreciated.
