Where you gonna be riding at??

The closest I have ridden to that altitude is up at Cold Creek (southern Nevada) and it's about 5,000 feet up there.

I tried it stock and although I did stall a few times after a long wot run when I came to a stop, the bike ran fine.

Where in the heck are you gonna ride at 7000 feet? Mammoth is 11 at the peak.

Id go get some nitro propane and not rejet. Not only do you not have to rejet, your bike will pull like it does as sea level.
