We have a 2004 Yamaha Rhino and SpouseAnon learned how to fix problems on youtube, also he's not shy. He calls up the local shop and tells them the problem and ask if they have suggestions. Time your call for times they aren't busy, or go see them. He's learned a lot just dropping in and talking to people. Everyone likes being the expert, and unless they are assholes or busy are more than happy to help. Keep in mind our town is small. Most businesses here consider it "good will". A service book helps but he mainly learned online and by doing.
