I have a ninja 250r('09) (european model so yes I have FI ..although no fuel gauge)

Is it possible to exchange the crankshaft from a 300r? it should be a nice bump in horsepower without any "mods" and if you want some port job and maybe a 1mm or 2mm overbore pistons it should be quite a power boost(compared to stock 250r)
