You said you were new to this so I'm just adding to tommy's post so you don't damage you or the bike. Support the frame (even just built up 2x4's underneath) before you pull the top fork caps.If you remove the top fork caps without supporting the bike, the spacers and springs will spring out and the forks will compress, dropping your frame and/or exhaust to the concrete and the bike over on its side pushed by the kickstand. Even supporting it, there is still a little spring tension but forks won't compress.

If you kill a man, you're a murderer.....kill many, and you're a conquerer..... kill them all,..... YOU'RE A GOD!!
