Looking for any help tracking down either the OEM part: 13033-130331058, or any small-end bearing that will fit my 1993 KDX250SR.
I fully realize the non SR KDXs run a different length con rod and pistons consequently with slightly differently positioned holes.
Have any other SR owners swapped out the con rod for a 88-90 KX250 one and thus able to throw on aftermarket pistons and more a commonly available small-end bearing?
Any information would be very welcome.

Thanks in advance.
