Hey, my name is Mike, Welcome to the board. I don't post here much, but I check it out often. If you are looking for info about doing mods to your 420a, I suggest checking out
http://www.2gnt.com They have plenty of information about your engine. I'm also 18, but don't worry, I have a girlfriend already too so I won't be hitting on you. I probably won't see you around at all though, because i'm from Hutchinson (a little ways away from you). Happy dsming.
