Im thinking to get this engine S12 TRPI Evo2, but a have question about the heatsink. In teamtrinity has photo of this engine and the heatsink has a different draw like the old sirio black heatsink, i visit the sirio site and the engine heatsink is different and the photo is of a engine with Threaded Shaft but in specification say SG Shaft, im bit confuse. I want this engine for a v1rr with centax
Thanks
The Sirio S12 TRPI Evo2 is the Ifmar Roar legal engine.
It does come with the big blue heatsink, slide carb, and SG crank.
In Sirio engines, whenever you see the letters AF at the end of description, it means it has threaded crank, and are now found on Sirios site under off-road engines. S12 TRP AF would be the Evo2 on threaded crank.
The on-road .12 engines are under Touring engines, and all of them have SG cranks.
Picture and description is correct for the TRPI. The only incorrect picture is the one for the TUP engine that shows a threaded crank, and should be SG.
Hope it helps
