Can You put a 300EX crank in a 250x?

[ss420ex]

not positive.... but i dont think so....
from what i hear.. the only difference in the 300ex and 250x engines is the crankshaft and flywheel.

no the crank/bearings/shaft diameter/flywheel/ and shaft ends are all completely different. if u want a longer stroke. go with a 300ex motor. if u want a new crank. buy another 250x motor..
