I started up the bike and again, the left pipe was significantly cooler right away which ruled out the coils. Once the bike was warmed up I recorded this video. It shows how the carbs are not in sync at idle but apply any steady amount of throttle and then they line right up. Release the throttle and they fall out of sync at idle again.

What does this indicate? Is it normal for carbs to "sync up" under throttle only?

(FYI: I haven't touched the sync screw yet. I recorded this and stopped. I hope to get some feedback before I go monkeying around with the actual sync.)
