Update:
I spent a couple of hours with Eric today to learn that everything was good with the motor, ignition and carbs. Turns out my problem is that the fuel tank isn't flowing!
Several years ago I had Norm weld up the hinge plate
and POR15 the inside. The coating is coming apart and sporadically blocking fuel flow. So I'm going to get the POR15 solvent and clean it out (that's why I selected POR15; because they have an effective solvent, unlike manufacturers of other coatings). The bike will then be a perfect runner.
However, the tank should be re-coated. I am choosing not to do that in case the buyer wants to get the dents repaired. Proper dent repair (pulling the dents instead of filling them) would destroy the coating. I'll apply a credit for coating.
I'm happy to work with a buyer to get any work done or to point to top notch professional repair (like some guy known as "Frosty").
Eric dialed the carbs in on a fuel bottle; everything's sync'ed and adjusted. Bike sounds great!
