Goto his website click on contact information and call him directly. That way you can talk him into a free t shirt or something with your order.

Lol okay, sounds good. Now that I know what to upgrade, letís go back to my original question. Is it possible for me to tear everything open and put it back together with no problems? I donít really have much experience when it comes to stuff like that. It I have been thoroughly looking at the service manual and it seems doable. What do you think?

Depends on your knowledge, and or expertise. I've tore down many auto engines in the past, and I've done a lot of work on the quads I've owned. I have never split a case, and have herd it's a pita! If you have the proper work space, & tools, including but not limited to a parts washer, then I'd say you should be okay. There may be a few specialty tools needed, for pulling crank bearings and what not. I had a heck of a time getting the cylinder head cover separated! I tried and tried and then my wife came out, and pointed at a spot and it came right apart with one easy tap! lol.

Well that's not comforting to hear. If I do tear it apart, is there anything I need to know in terms of what I need to adjust. I know I need to adjust the valves and the cam chain right?

If your engine case is cracked like you said, then you have nothing to loose by taking it apart. I'm interested in knowing what came apart to crack the case.

Yea, you have a point. I'll take pics when I get into it. Might take a while since I'm kinda busy. Just taking apart everything else right now to get the engine out.
And I also wonder what happened. When I drained the oil, coolant came out first followed by oil and some metal shavings.

Just came across this on ebay...although I'm thinking it's a little much since a few of us on here bought the whole machine for around $2,500. At any rate, here's another option in case you'd want:
