1. Stick to regular, you don't need higher octane, try to find non ethanol fuel if you can.
2. You will get ten thousand oil recommendations, I say pick a well know brand of your choice in 10-40 or 20-50 synthetic and don't give it another though.
Make sure it is for bikes with a wet clutch. Also look at the sticky about the oil filters, there are some out there that were not made correctly (missing holes) and you will seize your motor if you install one of these by accident.
3. Download and print the technical manual and supplement from the tech section of the forum and print out the pages as needed. If there is something specific you need help with ask here and you will get it. There are a lot of sticky post full of tips and advice, read them all.
Congrats on your TW, welcome to the club!
