Help me with my clutch please!

Ok, I want to get the JBS setup, but I want to make sure I don't need to fix anything before I get it. Here's the deal;

I have a 2010 Grizzly 700. I'm running 29.5 Outlaw 2's (skinnies), 1.5mm shim, white spring and 16gr greaseless weights. I got stuck in some peanut butter type clay, and it was so bad that in low, it wouldn't turn the tires at all. Now, everything feels normal until I get in mud, and then it feels like it's lost all bottom end. Even in low, it feels like I'm lacking wheel speed, like it doesn't want to spin the wheels up where it normally would. Is my wet clutch toast?

tear it apart and take some pics...could be wet clutch or something with cvt
