Fura, what process for break-in did you use, and what fuel.
What temps where you running, how was compression set (shiming).
I have a Sirio Evo2 for 3 months now, and after changing my conrod, have no problems with it. Yesterday I placed second in our local championship race and the engine is still tight and well.
Wan't to know this, because I was planning on buying a second
Evo2, and maybe ther is a batch of bad engines from USA.
