Wow I just came across this site. I've been riding around my yard for the past 2 weeks on a xl 500 s that i bought from a dude that inspected my truck. it was sitting in his garage and offered it to me said it hadnt run in years. I took it home soaked and rebuild the carb and the thing runs like a bear. I didnt know what it was or how popular it was. and I bought the bike for just 50 bucks. it needs a couple cosmetics but its now my favorite toy.
