the stihl 028 bearing works well as a headache free replacement.

the wrist pin it self is too short. there's nothing wrong with the stock wrist pin though, so no need

Unfortunately once the rod small end is damaged, a new wrist pin bearing will not last long.
A Oilite bronze bushing may do the trick for you.
Learn about them, may need an oiling groove or holes.

check out the wrist pins I list on my site: http://www.dragonfly75.com/motorbike/vibes.html
Do you have a high compression head but not an aftermarket CDI with retarded ignition timing? (which is needed when you increase compression otherwise there's too much stress on the bearing)

I have found premature wear on my wrist pins as well. One thing I noticed this weekend while drilling a pin to lighten it was that the ends were harder than the center section. My guess is these pins are electronically heat treaded. Clamped between two electrodes thus getting hotter on the ends. Just a guess. The drill was hard to start but got easy as we went through the center section. I too am looking for better pins.

Could be, or case hardened. Or inductively hardened.
Hard surface to resist wear and brinelling, ductile core to resist fracture.
