Not necessarily. I had similar issues as you had on my Bonnie for the last 2 months. Hard to start, surging and bogging idle. Pops on overrun. Most of these problems would clear up as the bike warmed up (except for the popping).
Turns out one of my manifold o-rings was toast. Replaced it today and the bike runs much better.
BTW, that's an enormous bill for cleaning out the carbs and changing out the jets. I'm not trying to make you feel bad about this, but unless they did a complete and thorough tear-down followed by a build-up with new seals, $350 could have simply gone to them spraying a bit of cleaner in there for 10 seconds and calling it a day.
