I've been saving up, and I'm finally ready to buy my first sport quad. I've got my eyes set on a Yamaha Banshee (https://volterrain.com/)—always wanted one. I'm going to look at a 2003 model this weekend. The owner says it runs good, but I know I need to be careful. What are the key things I should inspect? I know to check compression and look for leaks, but is there anything specific to the Banshee? Also, when I shop bikes for parts after the purchase (because I know I'll need something), which online stores do you trust the most? I want to be prepared. Thanks for the help!
