Having issues going past 8k rpm in 1st threw 2nd

It certainly sounds like fuel starvation but bad gas is always bad gas and would make the bike act up at any rpm.
I just put fresh none ethanol and octane booster and it still does it, it will do it all the way to 4th gear

Found this. It may not be your issue but good place to start I think

Is there anything in the owners manual? I don’t have my manual near me but I wonder did you mistakenly turn on the speed limiter? Not sure if the speed limiter will limit rpm’s like it does mph but I accidentally turned mine on one day and it blocked the cruise control from not working. Just a thought because I’m not sure.

Correction, blocked cruise control from working. I could turn on my cruise control but when I tried to set the speed the word “Set” would flash and the speed would not set.

I remember the manual said the speed limiter will limit the speed to the mph you set it but if you twist the throttle it will still accelerate so that’s why I’m wondering if it will limit rpm in 1 & 2 but allow for higher revs in higher gears. Anyway just a thought something to check.
I will check but it does it in 3rd and 4th as well

Gotcha I miss understand your post, let us know what you find.
No your good, I think it might be the injectors

Some more info, if my old memory is correct I remember when I had the speed limiter turned on the word “Set” for the cruise control was a different color than usual.

On a brand new Hayabusa? I been on this site since early 2022 and no one else has had injector issues on a gen3 so I recommend doing more homework before tearing into the injectors.
I was reading on the gen 2 page and they have a guy that had similar problems to what I'm having

Try replacing the fuel filter, test the fuel pressure, (should be 3 bar) and fit a new set of spark plugs to start with.
Is it out of warranty?

New 2022 Busa limited to 80 mph and 5000 RPM | New Owners Forum
Just passed the 600 mile break in and had her serviced at dealership yesterday. Bought the new Busa three weeks ago. On day 1 the dealer set the RPM max to 5000 on the SDMS which was fine. Indicator lights worked fine and I could get bike up to 80mph. After my first service I deactivated the...
It's at the shop now. It's under warranty.
Secondaries were my culprit.
I had similar running characteristics when I plugged in my freshly cleaned injectors that had sat in the box for four months. Very strange to say the least but when I rolled WOT, it wouldn't rev past 6000-7000 RPM so I just kept hitting it until finally it broke loose.
I also ran/run a liberal amount of berryman b-12 chemtool. 3508 miles later since the Sturgis run, everything is running as it should.
Now, that being said, I did have issues after a very early teardown of the fuel system. There was a lot of stuff clogging my injectors. That's why I had them cleaned. I also filtered out the gas tank, so there was a fair amount of certainty that the fuel system was pumping fresh, clean fuel.
Runs exceptionally well now.
