Have a 73 cb750. the frame is stripped except for the swing arm and the forks. the problem i'm having is the pivot bolt will not come out and i can't remove the swing arm. tried tapping the bolt after removing the locknut, but it wont budge. any ideas?

Put the nut back on the bolt, but only till it covers the threads. Then smack it with a hammer. It will put up a fight, but will come out.

Nothing worked, until I realized it was 30 degrees in the garage where I was working. After I put some heat on the bolt and housing, it finally broke loose. If you remember, when metal is cold, it expands; when it's hot, it contracts. When the tolerances are tight, that little bit can make a difference.
