The motor is so smooth at 3k rpm. Then I start to feel the vibes around 4K and they peak around 4.5K. Cruising at 60mph is disconcerting for sure. I am taking it in for the 600 mi check next week (and the recall fix) and will ask if the throttle bodies are out of sync. Otherwise, I guess riding in 5th is the answer at 60 mph.

I also mentioned that at a constant speed, the bikes surges like its misfiring. I thought maybe a TB sync would help. The tech rode and felt the same thing, especially at lower speeds in any gear. He suggested it might be lean fueling to meet EPA requirements but would submit the compliant to the Yamaha on-line tech support.
FYI. Even though the owners manual says a throttle body sync should be done at 600 mi, the dealer's list of required service (as shown on his service dept computer) does NOT include syncing.
