Wiseco will not do anything for you.
You'd have to have proof beyond a reasonable doubt it is not your fault.
In other words...
Measure any and all clearances, proove the jetting, ignition timing and fuel quality were all up to snuff...just to name a few.
Unless you kept detailed records of this AND were a big name shop, they're not going to do anything for you...
I've never personally had a wrist pin or pin bearing fail...but there's a first time for everything...
Just double check your installation.
I'd like to see pics of the pistons, top side and underneath the piston dome, cylinders, rods, what kind of oil, fuel, compression, etc....
