Default Throttle drops off at high acceleration

Lately Iíve been noticing the throttle acceleration drops off sometimes even though my hand remains steady on the throttle. Itís especially apparent on hard acceleration like when taking off fast from a traffic light. Change oil regularly, plenty of gas, so what could it be?

Everything is stock, clutch as old as bike from when I bought it in 2011.
What I notice when this happens is that even though I’m rolling steady on the throttle the engine suddenly downrevs at some point like it gives up. I don’t observe it when I roll slowly on the throttle, typically just on fast takeoffs.

You said everything is stock. How does your air filter and air box look? Are there any hoses that may have come loose and are sitting in the wind now?

As above post states, air cleaner first check. Next if you have never replaced plugs that is my next step this will also let you see what is happening inside the motor by what the plugs look like. My next guess would be fuel pump issue, clogged/dirty injector(s).

Just had recent maintenance, would hope they’d tell me if any issues with air cleaner or plugs. One concern I had was a lot of rust around wires by the steering but the shop said it’s not an issue. I’ll have them check fuel pump next time.

You may hope they even looked at stuff but 95% of shops suck! I haven't found a good one in my 30+ years of riding.
Ok by recent maintenance, are we talking oil change? Valve adjustment, steering adjustment, coolant flush, brake fluid flush, Air filter replaced plugs replaced how many miles on the bike?

Sounds like clutch. Check or play on clutch and adjust. Most bikers burn clutch. Not saying is burned out but Stryker takes minor adjustments to avoid clunking in first place.
