Hey guys, lets cool it down and put things in it's real proportions. This whole issue started by somebody posting a picture of his broken crank, and questioning the quality of Sirio engines.
After observing them I posted my opinion that it was caused by long periods of overheating, which was then admitted by the owner.
TG you jumped in, selling the idea that Sirio engines have bad quality and that Nova based engines were superior blah, blah..... and somebody else, posting pictures, said that not only Sirios break but also Nova based engines do, if mistreated and or badly tuned, idea which i support and also that there is no perfect engine.
You are a manufacturer and I bet your engines have their share of problems to, but it is not ethical for you to induce a thinking that every engine out there...except your's..... is a piece of $%&&.
Give constructive advice, because you are not going to sell more engines by trashing the competition.
State your strenghts and prove them on the track with results, and help others, if you wish, giving advice on how to avoid desaster, but not throwing $%$& with a fan over other brands.
AMEN
