Engine swap

[schachterle]

Will any year xs650 engine fit in any year xs650 frame(more specifically a 1971 xs frame), or do some years have restrictions, and what are they?

- as far as i am aware all versions of this motor fit into all versions of these frames...i have an XS1 motor in a 3L1 frame and have put an XSB 447 motor into a 3L1 frame and a 3L1 motor into a TXA frame
