42 is pretty large when looking at the pilots. Your bike is already setup from Honda to be rich at idle, so increasing to 42 would only pour more fuel into the motor, likely fouling the plugs after extended low RPM riding.
You don't indicate what needle clip position you're running. Pods make things leaner, so typically you will increase the Main jet, maybe also move the needle clip down to enrich the mixture. And you didn't indicate the air screw mixture settings? The 4:1 Delkevic won't effect diddly. The rebore, unless paired with a healthier cam shouldn't effect too much either.
If the bike were setup for riding in Utah at elevation, it would normally be setup leaner not richer given the thinner air. I'd also like to see 4 stock jets in all 4 carbs, as aftermarket jets are NOT the same as stocks.
If your carbs have a mixture of stock and non-stock components, especially between them, you will forever chase your tail tuning the bike. Forever. Pull the carbs, pull the brass, replace with all stock brand components. Maybe order a set of 105 MAIN jets to address the pods. 38 or 40 Pilot jets will be fine. 42s, not so desirable.
