As a follow-up to the few responses against your question:
-Just remove the pipe, radiators, gas tank
-You can then pull the head + cylinder to take care of your business
I did mine about a month ago, using kawa's service manual and information from this website as references. The info here is good, whomever wrote the manual left out a lot of descriptive information/verbiage which I consider necessary. The online material you will find is especially good for cleaning the KIPS valves and subvalves.
If you don't already have one, you'll need a special wrench that fastens to your torque wrench to torque the cylinder nuts back down to specification. The one I purchased is a motion pro brand I believe, seems like I ordered it from dennis kirk.
I got my piston, rings, bearing, and gasket set from rocky mtn atv, they had the best price at the time, I think it set me back $135. Watch the gasket sets, some do not come with all of the gaskets you need - resonator gasket on the side of the cylinder and coolant inlet on the head. I just bought some material and cut my own.
Good luck my friend.
