The ninja engines had some growing pains. The OS TZ engines are notorious for rod problems. Especially if they are modified. You don't hear about these problems with Novarossi engines. I have never broken a rod on my Sirio .12 engines either. There is a reason why some engines cost more than others. This has been my observations over the past 3 years.
OS TZ's do have rod problem... I remember that I broke a TZ's conrod even before the first gallon of fuel. And like Scott Fisher said, engines suffer even more if they are modified. Honestly, even with Novarossi, or any other engine, I always change my conrod each gallon. As well as the conrod pin. Its better to pay $35 each gallon, than $500 after 3-4....
