I don’t know how many people have done valve clearance adjustments but I have done several. Although this is my first cross plane valve adjustment.
Basically I did the valve clearance adjustment and put the bike back together and the bike stopped working.
Process:
Took the bike apart. Got to the shims, replaced any shims that I needed.
Most important part is putting it back together. So the manual tells you to align the crank mark (k |) with the timing hole when the #1 piston is at BTDC 105. Then align the cam sprocket marks with the mating surface. I did this then I checked to make sure it was right by doing the valve clearance procedure by checking that the lobes are facing away from each other at piston #1 then #3, #2, and #4. Everything checked out. Then I put the bike back together (without the air box. Connected the fuel tank and the the engine cranks and cranks and cranks and nothing:(.
Trouble shooting checks:
Checked that fuel is going by connecting the fuel tank connected and disconnecting the hose. Fuel pours out. Check!
Checked the spark by disconnecting on spark plug then touching it to the ground and using my fingers to feel the shock. Lol got shocked so check!
Checked the connections:
Ambient air sensor check AIS system connector check Throttle position sensor check Throttle motor check Fuel injector connectors check Coils plug connectors check ECU small connector check Crank position sensor check Gear position sensor check
And nothing:,(
I have no idea what could possible be wrong! Please help!!!

Something that might be important is that I installed a power commander on the bike. When it didn’t start after I put the bike together I uninstalled the power commander and checked all the connections the bike still didn’t start.

You said you have fuel pouring out but is the fuel actually pumping? Can you hear the pump priming when you turn the key on? It should prime for a few seconds. Also is there any check engine light?? If there is that'll point you in the direction of the problem. If not then it's probably something simple.
Aldo did you install the PC while doing this service or was it installed previously?

The fuel does prime. And there is a check engine light but it’s just for the O2 sensor. It’s because I have an aftermarket exhaust. I just bought the PC. And installed it during the adjustment

I also checked the fuzes on the left side of the fuel tank, by the ECU.

Your fuel test just proves the fuel pump is working (that'sthe way I read it). Are the injectors working? If you get spark I'd think the issue would have to be fuel related. Doesn't the PC plug into the injectors, did you missing plugging them back in?

The only way I know the injectors are working is by hearing the loud whine noise. It does this. As for the power commander it’s pretty straight forward, the PC gets connected inline with the stock connectors. From left to right.

Keep in mind the bike doesn’t run even without the PC

I'm still learning about this bike, but the noise is just the fuel pump. I think its fuel related since you confirmed spark. As posted above, might be the injectors are plugged in incorrectly. Since the PC plugs into them could possibly have gotten them backwards. If fuel is fine the only other thing I would think it could be is timing out by 180°.

Ok so I did the timing one time then put the bike together then I thought I did the timing wrong. And I believe I did, so I took the bike apart again and did a 180 then put the bike back together and nothing still not running. Would spinning the crankshaft counter clockwise checking the (T |) lobes are facing away from each other then checking the lobes on #3,#2,#4 position be a valid check to see if the timing is correct?

As for the power commander it’s pretty straight forward, the PC gets connected inline with the stock connectors. From left to right. The loud whine is the pump, not the injectors. If you can put a finger on each injector while it's cranking. You should feel them clicking when they fire. Since the pump is running if the injectors are clicking then you've got fuel. All that's left is spark and compression. Are all the coils plugged in properly? If so are you sure you're getting spark? If you are then compression is all that's left. Seeing how you were just in the valve train my bet is the cam timing is off ever so slightly. Hopefully not enough to bend any valves

I also turn the crank counter clockwise always before I put the valve cover on to make sure there’s no binding.

Here is a video of me checking the injectors

You should be able to feel the injector clicking when it's cranking over. Judging by the sound it sounds like compression is good so changes are the timing is fine. One thing I don't hear though is the fuel pump. I hear the electric motor for the throttle but not the typical "psshshhhhh" from the pump priming when you turn the key on.
Also where are you located? If you're near me at all I'd be happy to come check it out. I'm in central MA

The fuel injectors don’t work, but the fuel pump does make a whine noise. I’m pretty sure the fuel injectors aren't turning on. How would I be able to troubleshoot this

So the fuel injector #4 runs when fuel is priming, but injectors #1,#2,#3 blink when the prime is over

Something's wrong with the wiring somewhere I think if the injectors are indeed not firing.
So to recap:
The PC was installed prior to you doing the valve adjustment You performed a valve adjustment Bike would not start after adjustment Removed PC as troubleshooting step but nothing changed
Silly question but have you double-checked all the electrical connectors? Have you checked the fuses? I'm kinda stumped on this one to be honest, especially with the seemingly odd injector behavior. Injectors should not be firing at all unless the bike is cranking.
Those throttle valves you see move at key on to establish a home position and they close as intended when you start cranking so that seems normal. I can't see any injectors actually firing in the video clip. There's definitely something going on and I'm willing to bet it's something stupid lol. Seems very random that the injectors all would suddenly not work when cranking.
