The new crankcase is stiffer than the old one and has a slightly smaller volume = faster gas movement and higher internal pressure.

Awesome engine, IMO the best .12 out there and I also never had any probs with the carbs.

Nova carbs do fit though.

I'm looking to buy the new XXXV. I'm wondering if there are any performances differences between the Sirio 2611 and 2653 pipe? Also I want to buy an extra con rod with the motor. Are the XXX piston sleeve and rod the same as the XXXV set? Thanks in advance.

Might just be an old picture. I thought the XXXVK is the latest sirio sedan engine.

after Picco made Torque for 2011, Sirio is probably the last one great cheap engine on the market now.
