Newbie needing help.

New to the forums and seeking some help.
I have purchased a 2002 Sportsman 500 HO and am wanting to do some general upgrades and repairs. I know the valves need adjusted first and foremost. My questions are regarding the body panels and removal. I can get the front unattached but not up and over the handle bars to move the gas tank. Any information would be greatly appreciated. I am sure there is a trick that I am not doing. Which is why I came here to ask the professionals. Thank you in advance.
