What year model/more importantly how many hours on the current top end? Most here feel that 75-100hrs is a good time for new rings and while in there a new piston and little end bearing isn't a bad idea. Keeping all that in spec reduces wear on the cylinder as well. Others will tell you they have run theirs a lot longer (and I'm sure you can as all my top ends done around 85hrs have still been in spec).
If it was my bike I'd be giving it a full fresh top end in the off season to ensure a trouble free run next season. If you just want to get the head done, you really don't need to even bother pulling the cylinder. 2 fresh o-rings for the head and thats it.
