Forged pistons like weisco and wossiner expand more than a cast piston like pro x or stock. Also there are different ring manufacturers and materials that have different break in times

You cant 850cc using a cast piston. 83mm is largest. Weisco and wossiner are only option for 85mm both are forged.

Did you have group k bore cylinders or local machine shop? Do you know what they set the piston to cylinder wall clearance?

Are you running the plate advance sensor or flywheel cocked?

Your sxr 850 has held together with advance timing, and exhaust restrictor? Did you use weisco , am in the process of building one, I'm kinda nervous about ignition and restrictor. Should I be? Do you run any special fuel, Did you set it up ,?
