I don't have quick and easy access to a parts list for non-US models, but if you can find out the P/N for the 650's pan and if it is 11511-26E01, then it is the same as the B6... and the B12. Since the 1200 uses the same pan, my guess is there's no change... but that's just a guess.
OTOH, Blade is offering oil pan repairs for this very problem in the vendor section. You'd have to ship your pan to California though.
