Also, how many miles on the bike now?
The gel grips will probably be the next step.
I really don't want to mess with sprocket size - yet. Frankly, I'm not comfortable putting the engine under load like that at under 2500rpms. Motorcycle manufacturers no longer publish horsepower and torque values on their engines - and it's a loss, because seeing where the torque peaks tells me if this engine is a screamer or a lugging tractor engine.
If it's happier at lower RPMs...I can keep it under 2500 for about 2/3 of my riding. Problem basically solved! If it's a screamer, designed to wind up...then I'm gonna cause problems making it lug.

I would meet up with another member and swap bikes to compare. And I would start checking all bolts with a torque wrench, starting with the engine mounting bolts.
Is the vibration the same on the center stand or only when riding?
Any modifications or work to the bike?
Let's get some details and explore.

Haven't tried it on the center stand.
The vibration is absolutely the engine and not tires. I've run it up and pulled in the clutch; and it all goes away.
No mods. Only 300-mile service. One "oops" - feeling in the dark for the side-stand, I accidentally toed the gearbox into first, engine idling. The usual: A lunge forward and the engine stalled. I'm assuming no serious damage because there's no change in the smoothness of the gearbox shifting.
It didn't seem to change anything; but I was still "breaking it in" and didn't want to rev it above 3000 in that time period.

If you are saying the vibes have gotten worse, was there a point it changed noticeably? And did you change anything else?
Stock mirrors are an engineered part of the handlebar dampening. An aftermarket exhaust or engine guards can change the harmonics. Did you check torque on engine mounting bolts? That's a critical point on the VFRs and ST1300s.
If the vibes are normal, there's no fear of damaging the engine.
Seems they're worse. It may just be because I'm getting more free with the throttle as the engine wears in.
But I seem to remember it smoother up to 3000. It may be just familiarity. There wasn't a sudden change, like something coming loose inside the engine.
I see on another thread here...a former member traded in his 2013 for the buzziness.
I also see here...reference to "adjusting" the Balance Shafts.
ARE they adjustable? Here's what's going on. I'm in a small town in the Bitterroots...a very-wealthy town, with a university in it; but smallish. Honda has one dealer; the one I bought from...the owner IS the sales department. BMW sells a lot here. Harley sells a lot here. KTM sells a few here.
Honda, Suzuki, Yamaha, not so much.
The Honda dealer/owner...had this one. Don't know why he bought it; but the way he tells it, it sat on his floor for a year. He had never ridden one and didn't know anyone who had. He had NO CLUE.
He wasn't even pushing it. It was like...there...I guess after a year with it, he figured I wouldn't be interested in it, either. It was only pre-delivery, when he tested it out before turning it over to me, that he saw what it was...yes, he's a rider; a rider in his 60s. The target market; and he was bubbling like a kid when he came off it.
Point? He doesn't KNOW these things. Nobody in town knows these things - I'm probably the only owner this side of Idaho with one.
So...if there's a need to set the Balance Shafts...references and TSMs and anything else, would be a great help.
