Why do some nuclei have negative gyromagnetic ratios while most have positive ratios?
Well, gyromagnetic ratio is the ratio of magnetic moment of charge to the it's angular momentum .
If this ratio is less than one means these both quantities angular momentum and magnetic moment are opposite to each other ,then that nuclei will may have negative gyromagnetic ratio.
And if this ratio is greater than one means these both quantities angular momentum and magnetic moment are in the same direction to each other ,then that nuclei will may have positive gyromagnetic ratio.

When γ > 0 the spin and magnetic moment point in the same direction; for negative γ they are still collinear but lie in opposite directions. Two particles with positive and negative γ's precess in opposite directions.
However, this doesn’t really answer your question, since the next question is, why for some nuclei do the nuclear spin and the nuclear magnetic moment point in opposite directions? I guess this requires more in-depth knowledge of nuclear physics than I possess.
