[QUOTE=houston;10798863]i was trying not to make too much light of this but many of the nova engines as of late have been coming with a subpar front bearing (compared to 17011 ) and have been causing some issues , the more of you guys that show your concern to serpent usa/desoto racing the quicker the issue will be remedied or email novarossi direct through their website

I have a few Nitro Tech engines. I think the front bearings are leaking and its effecting the tune.Also the steel rear bearing seems to develop a little lateral slop prematurely.Love the engines but need to address the issues.

Does the Nitro Tech come with the 17011 from factory or something else? How can you tell if its a 17011?

Also whats a good ceramic replacement for the rear bearing?

Can I purchase these bearings from you?

Thanks
