I ordered a service manual as soon as I got the quad home, and I bought an owners manual online in .pdf form for $5.
The service manual is very helpful, but having a forum where you can get help from others who have been there before is invaluable.
I remember trying to work on my cars and bikes 20-30 years ago, and even with the manuals I finally just gave up and started paying to have the work done at the dealer.
After my experiences with this quad, I'm more inclined to start doing the more straight forward stuff on my cars by myself. I'll invest a little in an inexpensive [but not cheap] air compressor and get an impact wrench and some basic tools and that will go a long way toward doing the basic maintenance, like brakes, mufflers, shocks, etc.
