I'm going to look at a used 2005 Rincon. It has 475 hours and 3500 miles on it, and it is listed for $3K firm. The factory tires were replaced (the owner said they were pretty worn, so they needed replaced) and the replacement tires are about 50% worn. I know very little about the rincon's. What do I need to look for when checking this bike out, aside from heavy scratching on the plastic/bent handlebars/heavy wear on the underside, etc.? Wiggle the front and rear tires to look for play? I've been told the listen for timing chain tick when it first starts? I'm wanting a reliable trail quad that can do a little bit of work too. Any other known problems on this quad to look for?
