Les..
3.0 x 15mm, and it's too small, even when the bore is reduced down to 25mm. TOok that one out to 3.2, but the accelerometer data indicates it shoudl be opened up a little more.

I'll be doing some experiments with my FAC one next year - I don't have all the tools and equipment with me on this trip - or even a shrono. Will also bring a machined lighter piston. However I have no doubt that 3.0 will be too small for a 30mm tube... 3.4 woudl be my guess..
