I also agree you’ll be g2g as the 100mm bbk slides right into the cases. Lots of meat on the bottom end of the liner.Not sure what model you were checking but the 21 Foreman 520 FM1 (manual shift) has the same crank, the stroke is the same, only the bore increased in size. The cyl "should" be a bolt on, at worst the cases may require some finesse to accommodate the larger cyl liner.
