springs dont bulge, the wire twists in effect in torsion. they dont go anywhere.

I thought about this, but there's no easy way of measuring them.
Because the ends are not free to rotate, due to friction on the end faces under compression, I thought that they might, a little.
But you're probably right, anyway it'll be really really difficult to measure any diameter expansion, and just a little clearance on an outer sleeve should be enough, if that's what's needed.
It's not falling off, it's an upgrade opportunity.

you can calculate the compressed length diameter difference

but that wont be the problem because as the clutch eases off the springs they will be shifting about. they are going to hit the post or the I/D of that bore whatever happens. i would be well inclined to get a fresh unmarked clutch basket assembly and chrome plate it for surface hardness. this should mean a smoother action clutch for where the friction plates slide up and down and should prevent the springs from marking the face of the assembly.

i may give that a go if i find a clutch basket cheap somewhere
