Just a quickie on the Polini kit,

do they come in 2 versions, one for standard stroke and one for 60mm?

I only ask as some may remember a while back my piston dinintegrated. Standard crank etc and I had 1.3mm squish.

Bought new kit from Beedspeed and ended up with 2mm squish??

Had this before when I changed a piston on me mates (Sean and Dan sorted it a few weeks previously prior to a H4H trip to Africa..... it's in an old thread,) and with the new piston he ended up with .5mm extra squish? Took piston out and measured, it was actually half a mm shorter from top of gudgeon pin to edge of crown.

Are we comparing later 2-ring pistons with the original 1-ring?

No mate, both times 2 ring pistons.
I fully appreciate manufacturing tolerances etc but 0.7mm difference on mine is shocking.
