Hey man, I've just had a look at your video too.

Have you taken the plug out to check if you're getting a spark? From a cursory glance it all looks pretty healthy.

I'm sure it's a stupid question but have you timed it up on the correct stroke? I'm having a memory blank but it should be timed on the compression stroke rather than the expelling stoke.

I have once seen it done where it was timed incorrectly somehow - with the cam 180 degrees out.

Timing must be set when both valves are closed. When you pull on both intake and exhaust rocker arms should get a little play

Yes, we had a new member who did a valve lash set. ...and scoot now would not run afterwards. Talking him through finding true TDC again, after he lost it....was not ever successful. Pretty darn sure he had set them on the wrong stroke.
Wouldn't run, and never heard from him again.
If you don't feel slight movement in those rocker arms - STOP....you're not at top dead center. Rotate engine again.

And make sure when crank/flywheel is showing on TDC that the cam is showing it is in the correct position. The spark fires every revolution from the flywheel/"pulsar" not from the cam. I said that to make sure! Your voice said you replaced the fuel pump. Did you mean the vacuum operated fuel valve?

Hey guys I was going through all of my images I have taken of my bike and I noticed there's a crack in my manifold boot gasket. I wonder maybe is this the cause of her not starting..

Maybe.
Something's not letting that fuel flow.

Yes the vacuum operated fuel pump

This is really picky but your fuel tank is above and behind the engine, right? There is no fuel pump. Gravity puts fuel in the carb float bowl. There IS  vacuum operated fuel valve that opens so gas can flow to the carb. It opens when the engine spins and the throttle is closed. Any vacuum leak like that crack in the intake gasket could keep that fuel valve closed.
