Gxv140 with gxv140 and gxv160 coils and neither fit the gxv120 but the gxv120 fits the gxv140 and the 140 chonda and I don't know if that would work as you can see the rear right hole has not been tapped .

Chonda SL1P60P =(120) without coil which are (the coil) interchangeable with chonda (140) and visa versa, the chonda coil works perfectly on a honda gxv120.
