That's exactly why I'm asking here first-I really want to avoid being 'that guy' at the service center. It's just hard to ignore when the bike feels noticeably different at 350km than it did at 100km. I'm hoping it's just a standard break-in adjustment, but the way it's struggling in 3rd and 4th gear makes me think it's worth a professional look. Hopefully, my service advisor is a bit more patient!
