I would use the GL-1 gear oil. There are a lot of additives in a fully formulated motor oil that are not needed in the transmission, and some that could affect clutch performance.
But honestly, for $10 every couple of years, just use Harley's Formula+. My Sportster shifted like butter with it and clutch take up was smooth and linear.
