my km90-come-mc1m project is coming along nicely, but at the moment im thinking that the n-1-2-3-4-5 gear pattern that the engine has could be a real pain. i know the later versions of the 80/90/100 kwaka engines had the normal 1-n-2-3-4-5 gear pattern. does anyone know what was changed in the later transmissions, for instance was a different shift drum fitted or is the whole transmission different
