Bearing issue!!!
 

Hi guys
I heard that some novarossi ceramic bearings have some trouble???
I have a Max Pwr XXL3 and the main ceramic bearing died at last race, I replaced with a novarossi OEM standard 11.5mm bearing and the engine is fine. Also I have a friend that pass the same problem with a Max Pwr and a novarossi 353 and other with a JP Eagle TL3 what's wrong with bearings,all those engines were treated well, exellent maintenance after each race. Any Feedback please!!!!
just for reference both Max and the JP were engines were new engine just brake in, cleaning and 2 races, the 353 just 4 races after brake in.

strange i have a nova engine 3sct and have been racing for one year without replacing the bearings, i must have done at least 14 races and practices....
