Getting up to the 600-mile service point...I'm no longer babying the engine so much...learning more about it as I'm covering more ground.
First...this concerns me. I should advise, my contact with big, conventional, chain-driven Japanese cycles has been limited. I've had two BMW boxers; and before them, a GL500 - with a driveline that was anything BUT conventional. Also had a TU250. And an SR 500; but that was decades ago and I don't remember much about breaking it in.
The question is...putting the thing in gear when the engine is idling, warmed up. As at a light. The CB...going in, it does it with a THWAK! and the bike jumps. I'd say it's a dragging clutch, except that it doesn't show other signs. Doesn't shift hard; clutch play is normal; I can roll it easy, engine idling or off, with the clutch in and transmission in gear.
The other big bikes never did this. My little Kawasaki toy doesn't do this. I think I remember the TU doing this; but with a smaller motor, much less drama.
Have I got issues? It's going in for service in a week; now's the time to get it looked at.

I'd go straight back to the dealer and let them have a look; mine slides into 1st like butter! No noises, no drama, no jerking, no nothing...

What are your rpm's when you do that?

Idle speed...1000 rpm.

My bike clunks into first gear also, but maybe not as badly as you describe. I've owned about 25 bikes in my lifetime (I own six right now), and my CB1100 makes the most noise of any of them when shifting into first gear from a dead stop,but I still don't think there is any problem with it - (have you ever heard some of these Harleys when they shift into first gear at a traffic light?). Have you checked your chain tension? A loose chair will definitely add to the clunking sound as the slack is suddenly taken out. MY CB1100 is the most sensitive bike I have ever owned with respect to chain tension.

It is not correct. Get it looked at.

Haven't messed with the chain yet. I figured since it was going in for 600-mile service, I'd let them take care of it and pick things up from there.
I've heard the Harleys at lights. That's why I've left it alone up until now. As well, I'm dodging it in other ways - flat-footing it forward as I shift into gear, helps some. The long lights, close to five minutes, in town, encourage me to kill the engine with the switch. So then, put it in gear with the engine dead, than crank it as the light cycles.
But it doesn't feel right. It's going in, as soon as I find time...I'm at 575 miles now, time to start addressing this stuff before something is damaged.

You should always keep it in gear when stopped at a light in case you have to get quickly out of the way.

Disagree. If in a hypothetical, someone is bearing down on you...you're not much better off charging blindly into an intersection against the light. And in fact you'd open YOURSELF to liability...instead of that tractor-trailer coming up on you, YOU YOURSELF are now the cause of the accident - by running the stoplight. Which is gonna affect insurance payout, who pays what - and will keep you from suing for damages from any other party.
And anyway, the injuries from a stopping vehicle striking your rear are probably going to be far less than being hit broadside by a vehicle which was NOT stopping and maybe didn't even have time to react.
Keeping the clutch in and a gear engaged, in a car, is hard on the clutch throwout bearing. I don't know the mechanical composition of a motorcycle wet clutch pack; but it's quite possible there's a similar source of wear that could eventually take the clutch out prematurely.

I've had to get out of the way or get rear ended twice. To each his own but I always keep it in gear at red lights. I knew a guy that got killed from a hit from behind while sitting at a red light
