Thanks Sirio, I also have never had a problem with a nova bearing except on a p5 front bearing but thats normal when you run in the dirt! There could be many things causing bearing issues "running to lean popping the plug and the wire gets in the bearing, running too hot as Sirio said , fuel quality what % of oil is in there, and so one" I don't think the problem is novarossi and you should not think twice when buying novarossi products, people complain of the price but you get what you pay for!
