Sure it's the right headset? ISO vs JIS.
1" threaded ISO headsets have 30.2mm outside diameter cups, whereas JIS have 30.0mm. Might explain the loose fit.
ISO is the most common 1" threaded headset standard, and you might've bought a JIS headset.
Ahh thanks, yes it’s 30mm. Another rookie lesson in the world of 1” threaded. Fitted it with bushing and bearing locktight , think it’s disastrous?

I would always advise to fit the correct size parts, but you probably won't die.
Did the crown race fit ok? I think JIS have different internal diameter's to ISO.
