I'm having trouble getting my swingarm bolt out on my 07 YZ450, any suggestions? Need to lube it up.

Buy a 4 or 5" (or longer) 3/8 coarse thread bolt and screw a standard 3/8-16 hex nut on it as far as it will go. You now have a swing arm bolt driver. The threaded portion will guide it by fitting into the center hole and the nut will drive the pivot out with a minimum of damage.

It's probably hanging up on the sleeves in the back of the crankcases. Apply some penetrating lube there.

I think everyone on tt has had this problem at one time. For me it was PB Blaster (this stuff is amazing) then I laid the bike on its side and pounded on the swingarm bolt being careful no to mushroom the end. Then more PB Blaster and it came out.
