Mark, If you havent taken off your chain already, you can put a piece of wood(2x4)through the rear wheel spokes and run the wheel around so the wood is agianst the swingarm. To remove the nut the wood should be agianst the top of the arm. Then put the bike in gear and tourque on the nut. The nut usually has like 80lbs of tourqe on it if I remember correctly. Good Luck
