EC 250 motor rebuild opinions

[motorhead]

Need to rebuild my sons 02' XC250,clutchside main bearing cage let go,luckily cases are ok. plan on doing top end as well while it's apart as piston to cylinder clearance is near max. The bike had a vesrah rod in it,I was surprised to see "made in japan", on the rod. The piston looks like a wiseco to me, which I've not had the best of luck with in the past on other bikes.I'm just courious of members opinions/experiences regarding cr250 con. rod crossover and wiseco/vertex/woessner piston reliability.
