Ive got a 1984 zn700A1 with the #3 plug hole completely wollered beyond a helicoil or timesurt being able to do any justice. But,Ive got a 80 kz750 head sitting on my bench with which I was wondering if its possible to do a head swap putting the 750 head on my 700. Will it work WITHOUT having to do some major mods? Any help is awesome...??
