SXR Zxi 1100 cylinder tolerance

Hi guys. We are currently working on a zxi1100 engine, we are putting it in a hydrospace s4. The engine is at cylinder service As we speak. What tolerance would you sugest for The pistons and bore? WSM recomanded or something Els? We are planing on raising The compression to 175-195psi. Thanks so Much - Nicolaj
