scrambler 50 and 90 HELP!

[91kx125]

will a 90cc crank rod piston cylander and head fit onto/into the 50cc crank case, i see diffrent part numbers per 90cc crank case vs the 50cc but to the eye on the partsfich picture they look the same.. any one know?

im very sure they are different.

The parts fische looks the same because every part looks the same and is layed out the same. They just dont pay the extra cost of creating 2 parts fische's that look exactly the same only the scales are a bit different.

Those parts fische's are just there for a visual aide, not to reflect parts looks and exact sizing.
