Well, I try to help the best I can. Granted, I do lose it occasionally with some posters. They're, plain and simple, mechanical morons. They have no business holding wrenches in their hands while they're near a motorcycle. They do more damage than they "fix".
I try my best to be "civil" but sometimes the stuff you guys do just pushes me over the edge. I'm not going to apologize for this, you deserve the brow-beating, even more (like the revocation of your tool set). There's a right way to do things and many wrong ways. I see the wrong ways illustrated here much more than the right way, even though I try to correct that with my posts.
The XS650 is a wonderful old bike. If you're going to pick an old classic bike to own, this is a very good choice - very long production run (near 15 years) and high volume production (over half a million). The bikes and the parts to fix them are out there, and can be had at a reasonable price (if you shop). Don't fall prey to the first eBay or Craigslist offering you see.
