After totally grenading my 06 YZ 250 motor, I was going to pull the swingarm bolt out thinking I was just going to get a fresh motor and all would be great. Well, after soaking the pivot bolt for two days in wd40 and occasionally hitting on it, I took the bike to Ryan at Factory edge tonight and between him, his dad and I we absolutely could not get this thing out. We tried heating it, swinging at it for 2 hours with a 4 pound striking sledge, and the motor is loose on the bolt so we know the seizure point is on the bearings, and even using a 20 pound weight as a backstop for the other side of the strike to break it loose didn't work. I've heard of using air hammers/roto hammers with bull points, but I'm just afraid of actually having to take it to a machine shop or cutting the axle between the swingarm and engine cases. Need some helps peeps, what ghetto ways can help me get this bastard out?
