(Newbie question alert...)So if you've read a few of my posts, I am a very new motorcycle owner and rider (4 rides so far!!). Tropical storm here in NC killed my first real weekend I would have had to ride. At any rate, I want to change the oil in my 500. I've done plenty of oil changes on cars, so my only question is: What type of oil do you recommend? I assume I can't just go buy some off the shelf 10W-40 I would put in my car for the bike. Should I run synthetic? I read about some other oil type, but I've already forgotten (ah Dino oil, that's it). I'm looking for something I can hopefully pick up at a local big box auto parts store (Advance, Napa, etc) and change later this week/weekend. I attempted to search the 500 forum, but didn't find anything too useful so I apologize if this has been addressed before.
