Hoping someone could tell me what size the rear axle nut is? I can't get a socket between the nut and the exhaust so I was going to buy a ratchet wrench, really don't want to remove the exhaust if I don't have too. Tearing down the bike for our short winter and sending pieces to the chromer. Any advise on the easiest way to get the rear wheel off would be appreciated. Tried to get the torque bar off but the bolt is to long and hits the frame? Looks like you have to take the whole dang swing arm off?
