New CMB 21 Piston/Liner being tested

I've heard the rumor since this summer but now I have some pics to show also. Mauro and some of his team drivers have been testing some new 3.5 cc piston and liner sets (in different spec crank cases to suit the new porting) before the introduction of the 2013 3.5 engine. What Ive heard its a new crank case being done also for the 2013 "Valvola" and improvements on the induction system...
