http://sfbay.craigslist.org/eby/mcy/569296016.html It says the valves need adjustment and the compression release needs to be adjusted too. I might go look at this today. Could someone PM me a link to a shop manual so I can look up how to adjust the decompression cable? What is the bast way to check to see if the swing arm bolt is stuck? Are there any other things I should look for when buying a used XR4?
