Default Re: very new to this motorbike thing with a few questions

I have a BikeBerry black 66cc motor I bought three years ago, and it has 10mm nuts on the head. So I don't think head bolt size is a very good indicater of displacement. The motor looks like a 66cc, with the square head, my 48cc has a some what smaller head that is more rounded looking. Just my 2 bits on the subject!
