not sure if this topic has been mentioned before,
has anyone seen or used a collari modded sirio engine? (there's an 'm.collari' engraving on the head.)

i came across 2 of them, one an evo2 and the other one with an orange head which is also based on the evo2.

i'm quite keen in getting either one, just wondering what their power is like.
btw, does sirio make engines with an orange head?

lastly, i've read tt d evo2 seem to have some durability problem (cranks breaking, weak conrod, etc...)
any truth in this? i've never run any sirio b4 and wana try the collari modded ones (i'm leaning twds the orange head version)...

any comment or feedback welcome,
thanks in advance!
