84 200x rebuild

[Merriman16]

Hi, I am currently working on my 84 200x and Im planning to bore the cylinder to 66mm. Do you think cast or forged pistons? Also, are the specs for piston to cylinder clearance the same when you over bore? Thank you

Yout new piston should come with the finishing instructions. That would be the piston to cylinder clearance and how to finish hone the cylinder.
