Hi guys, recently bought a bike with no ignition switch. (it was cutoff). Would this be compatible?

It is a 1975 CB750.

Yeah it will work for the time being. After some time (different for every bike and person) the switch will fail tho because it uses too small contacts. The other choice is NOS OEM ($$$$$$$$$$$) for the part which is why the cheap switches sell so well. Consider investing in hondamans key saver relay kit which is a very cheap and plug and play alternative. You more or less get your cake and eat it too

Do you happen to have a link for the "hondamans" method? I searched it but nothing came up.
