piston bores?

[400exrider707]

I was wondering what overbore each size engine is like for example a 406 would be like (.040 over) I dont know if this is right but just an example. so what overbore are the popular engine sizes?
406
416
426
440?

i believe its

406 = .040
416 = .080

Im not sure about the others, cause i think 440 is .120 but thats on a different sleeve, so im not sure :ermm:

40, 80, 120, 160 over (in thousands).
