what size bearings does a nova 21+4 require, i need to replace mine and am unable to find a straight answer, it is a nova 21+4, steel bearing engine. I plan on replacing the rear bearing with a ceramic, leave the front as a regular steel, or should i just put 2 ceramics in it?
Rear bearing is 14 x 25.8 x 6 I would go with the steel nova 17011 front bearing and ceramic rear.
