Hi Font,

Actually the motor is not 100% setup yet because there is a .10 difference between the two squishes because of the one barrel being a tad shorter than the other. The one head volume is also not 100% the same as the other.

It does not really matter in this comparison since the differences where there with the single ring pistons a year ago too...

Will have these sorted in the near future and some more mods, will post my findings.

The single ring pistons were Wiseco GP. (RM125)

Cheers
Mario
