Damn 4pokes I don't have a clue. your best bet is to open her up.
If your having issues splitting cases try hitting it with a rubber mallet, not too hard, just enough to split them
you definetely do not need a special tool to split the cases because i have done it a million times. The cases are pretty durable and you will have to hit it pretty hard to split it. Let me know if you have any questions because i know a lot about this quad and have a million parts for it.
ummm fabb take it easy dude,you cant really be sure if tis really him,even if the name is the same and yea dont post info of a person around the net without permission, and your brother closed the thread cuz he doesnt want more talking of this,keep it to yourself.as for the topic you definetly need a special tool.
