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)

Hi Kostas, you should contact @
micoulisninja - he can tell you everything about that.
But one easy word from me about engines, the longer the stroke the less the engine likes to rev up to higher rpm and if you do the more early it will break
