Motorcycle DIY HELP

[IRL_Reject]

I am trying to change my sprockets and chain out.
Except there is one fucking problem
I CANT GET MY FRONT SPROCKET OFF
I got the nut off just fine with an impact wrench, and every video I have seen tells me that the sprocket should just slide right the fuck off
Yet it isn't doing it for me
Did these niggers add some kind of adhesive like loctite to this shit??
if so I am fucked because I don't have any way to apply heat to get this shit off

On youtube they are just showing me that this shit should just slide right off
