Its quite possible you got one of the Mk2 engines which mysteriously are far improved and dont have the same reliability problem relating to the conrod. [/B]
Actually they were engines bought in the USA (Trinity*&%$)
I bought my engine (Sirio S12 Evo2) in Europe (Spain) on October 2003, and didn't come with the new big blue cooling head????
So you are saying there are two batches of Evo2 engines???
How do we know which engines are MK1 or MK2.
