Looks like 76cc to me
I am not 100 percent sure.
We will let the experts be the judge.

Have fun

With stock style flattops, you would have about about 8.5:1 compression. I would put either some 64cc heads or domed pistons in it if you want more compression.

the pistons just have the valve reliefs and come up to near zero deck height.
