ZStar/Gio 125 Piston Replacement

Hi, new forum member here from Calgary, Alberta, Canada... just picked up a 2008 ZStar 125 big wheel last night that has only 60psi compression, was wondering where I can get a piston for it preferably in Canada? Can a person big bore this bike and if so to what cc limit? What cam works well if I was to big bore it?

I'm in Calgary too. I have a 250cc GIO and needed a new piston, rings and valve seals and got replacements from Aliexpress and Amazon. I tried the local store but they seem to be closed. I've been pleased with parts from the above. It's a Chinese bike so Chinese parts should be fine for a while.
