Hello,

I was surfing on the internet and this was coming by.

http://www.gw-racing-parts.de/index2...is=2010&lan=en

Search for this article name: PCPXT660/04-09/100mm

Did somebody tried a higher compression piston with the stock cylinder size?
And so yes is this recommend? HP gain? torque gain?

Is the diamond honing really necessary or only on a engine with allot of km's?

Greetings,
Thom Plas
