Do high compression pistons make a big difference?

[Honda2000]

I am thinking about getting a high cmpression piston for my 200 ex. I was just wondering if it would make that big of a difference with stock bore? I have also heard of people having transmission problems after getting a piston. If it helps i have a stage 2 cam k&n, pro com revbox, and a slip on pipe.

it would go good with the mods you have. most ppl pipe it, cam it and put a piston in at the same time, and you have everything but the piston, but i have a piston for you if your interested.;)

did you have this piston already installed? did you notice that big of a difference? What compression ratio is it and what brand is it?

For about $50 - $75 you could get it bored out. You will have to get it honed reguardless. If I was going to dig in I would make it bigger.
