Hello Trevor and welcome to the site. Unfortunately I'm one of the carb fellows but this issue has cropped up a couple of times before. I think the other fellows with the problem ended upping their idle speed to address the issue. Have you checked the obvious issues like intake leaks that might cause the bike to run too lean at idle.
You might want to reinstall your oem equipment and bring the bike to the dealer and complain. A lot of fellows have the EFI bikes and don't have this issue. If the dealer can't fix the flat spot, go up the complaint chain.
