Motorcycle running lean after removing 25kW restrictor?

I recently bought a 2008 Honda Hornet (FI) and it came with 25kW. I removed the restrictor because the bike was really slow but now it's running lean - the acceleration is really sluggish, sometimes it stutters and it turns off most of the times I pull the clutch. Any idea what it might be? The spark plugs were already changed and the air filter is clean, it only started doing this after removing the restrictor.

Correct Oil sight window correct level on motorcycle?

I have a Honda cbr600rr 2014 and I use hp4s oil 3 quarters. I changed my oil for the first time this spring and I never checked the oil after the first two days for leaks and so on and today I saw through the window that the oil is in the middle and was all the way on the top. No leaks no bad color no nothing. Am I burning oil or am I low. I will attach a picture. Thank you Correct Oil sight window correct level on motorcycle

Have an old Honda VT 500 E Motorcycle. Seems that the regulator / rectifier becomes very hot in working condition. Also the voltage is a bit?

To high: probably 14,6 V. After engine stop the battery is overloaded.
My Question is additional cooling can be a solution or not?

Added (1). Measured with a DMM for certain!
&
Battery is 14 Ah lead-acid battery

Added (2). Is a new Battery and 1 stage bigger than the original; instead of 12 Ah it is 14 Ah one. And no all cells are ok, after charging the Battery has 12,8 V and keep this voltage over the time.
Regulator / Rectifier is already with finns and i mean i can always touch it with my hands. Therfor the temperature isn't over 50° Celcius at the finns.

Help me figure out predict what happened with my bike?

To start. I have a honda shadow 1100.
recently did some carb work myself its the second time i did it.
i noticed the intake is a little rotten. I might need to get a new hose or two for the intake because it really isn't long enough.

so. I went for a ride today. Came home, left the bike out for like 3 hours. Went back out with carb clean and sprayed down some old fuel. I recently replaced the seals on the carbs.
i turned the bike on, and BOOM. Sounded like a gunshot.
and after that, my light, which used to only have the two options off or highbeams now has low beams and high beams with no off button?
so i took it for a quick spin
now one of the engine blocks sounds different.
now once it gets into higher RPM it sounds more like… I don't know a roar mixed with a motorcycle rather than just a motorcycle.
when i got back, i turned it off, cleaned some more gunk off the heart of the bike and tried to turn it back on only to find. My battery is dead.

battery is now charging.

what went wrong? Any ideas on where to start?

Added (1). the irony is the bike was working better than usual this week
