Am I paranoid or???

Are these bikes just loud or to I have an issue that wasn't addressed with all that effort? I reshimmed all of them to spec. Adjusted the tensioner, 21 pins and timing was set right to the book. Bench synced the carbs, fixed the leaking float.  It sounds way better in person then before and responds way better but I still feel like something sounds off

What they said. CVs have to be synced with the bike running. Also they're noisy engines.
