I went looking for Full Complement bearings to replace the Moose Stuff that I had. My local bearing supplier was unable to locate full complement bearings (full complement being w/o cage, providing more needles, and higher operational loads). The bearing I was after was an NSK F-2216 (F = Full Complement). I ended up with NSK HK-2216 and NSK HK-1612. These are German bearings, good quality. I paid $5 for the 2216, and $3 for the 1612. However, they are caged.
My guess is that the capacity is less as you have a cage, but you can pack more lube in with the cage. I haven't installed these yet, but I will once I get some time. I also bought the Jet Lube, but haven't used it, either.
These HK bearings are the exact same bearings that Kawasaki used/uses in the KX250 two stroke.
Did that help, or was it total blather?
