Removing front sprocket

I am having a of a time getting a front sprocket nut off one of my bikes. I have the bike on two sturdy stands, in neutral, sprocket nut washer is completely flattened, I have a pipe wrapped in a towel b/t the swingarm and wheel. I am sitting on the bike stomping the rear brake while my gorilla armed dad is turning the breaker bar. Nothing, he's lifting the bike up. No luck with a 4' cheater bar either.

HOWEVER, I'm gonna bring the impact gun home from the our shop tomorrow as well as a torch. I'm hoping the shock from the gun will break it loose. If not were gonna try heating up the nut for 20 seconds or so and go from there. Also gonna buy a good quality impact socket vs the one I'm using. I'll report back tomorrow maybe. Am I forgetting anything?

I actually already sprayed some on the threads and let it soak a min. Nothing.
I'm thinking the shock of the impact gun will get it. We shall see

The impact gun didn't do a thing!
We even heated the front sprocket with a propane torch.
Nothing. Impact gun nor breaker bar w/4' cheater.

After we torched the out of it, we decided to go back the WD-40 route.
So we sprayed a bit on and gave it another go.

So, what did it take? Bike on the front triple stand&the rear spool stand, a piece of metal wrapped in a towel placed on top of the swingarm through the wheel so it wouldn't turn, my dad and all 250+ lbs of him sitting on the bike holding the rear brake and going at it with the breaker bar and 4' cheater bar. I held the socket in place and he gave it everything he had. Eventually, it popped. I physically could not have done it. His weight on the bike helped a lot too. So, problem solved

I went out and bought an impact socket vs. the other 27mm one I had. That sucker was EXPENSIVE! Sheesh! O well, I'll use it again soon. I feel more comfortable using the 6 point impact socket so I bought it.

This was my first time to use my rivet tool.
I tightened and pressed it as much as I could.
My dad gorilla armed the rest and got it a bit more tight.
I wasn't sure if this is okay as is.
The stock master link on my 10R is flattened a bit more but we gave it all we had. . .

I usually fire a bolt into the garage floor hen chain the breaker bar to it, tightly.

Then I put the bike in reverse and let the engine's torque break the bolt for me.

It would, BUT the impact gun wasn't enough.
Breaker bar and 4' cheater did the job though.
