Go with a Wesico 10:5:1 piston.Bore it 2 thounsad of an inch.It wiil be your safe bet.

For the piston I would also go with Edogs suggestion. I have put higher comp. pistons in the 200x's and it is not really worth it. As far as boring goes, only bore it out if you need to. Boring doesn't really do anything noticable as far as power. You should only bore the cyl. if you need be. Like there is damage on the cylinder walls.
