wristpin bearing?

Hey guys...so ive finally ordered all my parts...i decided to go stock on everything...I was just wondering though, where the hell do you find the wristpin bearing? i wanna ree it but i dont see it on the parts diagrams anywhere. All i see is the rod but no bearing in it...any help would be great...its probably not a big deal but i wanna relace it anyway....thanks:ride:

Assuming that you are talking about your kx250f, wrist pin bearing is on two strokes. All you have is a wrist pin and two cir clips that connect the piston to the rod. Cheers!

It would not hold up to the massive force that a 4-stroke puts on the rod. That´s the reason. A needle bearing does not have enough surface support to cope with that kind of forces. It would break in seconds.
