HI, i am looking at the choices of bikes for next year all ready and possibly going for the new KTM. I no most of them are using the 450cc EXC bottom ends with the 590cc big bore kits on. Just wondered how much work is it to fit? with regards to, Ignition? Carburetor? and if there are any necessary mods to the head or crank cases.
Many thanks.
