what are your thoughts?
i always used tko ceramics in my nova engines but this one is my baby and dont ever plan to part with it
Between novarossi steel and ceramic:
if i were you i would go with the steel novarossi bearing. For the price of a ceramic bearing, you can buy 2 steel bearings and run the motor for almost twice the hours than with a ceramic. I say "almost" because i believe that the ceramic bearing may hold a little more than the steel due to reduced friction. But still 2 steel bearings should give you more running hours. Also, for me the performance gain doesnt deserve the extra $$ for the ceramic.
thats my opinion,
btw, i just installed a ceramic tko bearing in my backup zx12. I dont yet know how this bearing holds, but heard good stuff about them and seem to be in a very good price. Have you ever got bad luck with them?
