I thought the KR1 and KR1S cranks were the same

indeed, not a single difference.
maybe she is mistaken with the KR250.

Awww! Sorry guys I just realized I asked her about a "1989 KR250-B2" should have said 1989 KR-1 250-B2.

It shouldn't make any difference - "1989 KR250-B2" is pretty much the official Kawasaki designation for the KR-1 of that year. As far as I know, manufacture of the tandem twin KR250-A (whether the A1 or A2) ceased before the end of 1987.
There may be some minor differences between the KR-1 and KR-1S crankshafts (part numbers were different), but they are interchangeable.
