HI. Got an 04 LC4 Enduro and am in the process of removing the swingarm and bits. The shaft that goes thru the swingarm and rear engine casing won't come out. The nut on the left comes off OK but then you are ment to drive the shaft out with the nut on the right attached. Except the nut is located in the recess of the frame by weld. Not actually welded together but the nut is held in place by the weld. Any idea how to get around or thru this?
