Wilsons Sandbox

Knowledgeable KLRistas, I have been lurking and absorbing the wealth of information available while riding my '98 as often as possible. I am working on building a FrankenKLR from my Ebay parts bike, and a legally titled frame in the secret laboratory out behind the house. While stripping rusted parts from the donor bike, I have come across a problem and seek the collective wisdom of my fellow wizards. I am trying to remove the bolt from the swing arm and from the bottom piece of rear suspension without the use of a jack hammer. I have managed to get both bolts to "rotate in place, but removal from the donor bike seems impossible so far. I would love to remove the swing arm and engine from the old frame to make some progress with my project, but between the current heat wave, and frustration with two miserable bolts, I am getting frustrated and want to ask for help before I attempt stupid possibly destructive methods. Any or all suggestions are welcomed. Oh, and on a side note, If I wanted to replace the springs in my front forks with spiffy cool progressive springs, do I need to disassemble the front forks totally, or is it possible to remove the old springs, and drop in the new ones without major surgery? I would like to minimize down time on the everyday rider..., It is a blue, '98. Not fast as the red ones, visible as the green ones, beautiful as the black ones, but loyal until it stalls out, blue.... Jerry [Non-text portions of this message have been removed]
