Motor oil is not nearly stable enough for forks:  the oil needs to maintain its viscosity under all temperatures, with very little deviation.  The "made for forks" oil is uber-expensive because it maintains its viscosity v-e-r-y accurately.  Automatic Transmission Fluid, in this case, Dexron III/IV, is what Honda used for many years.  It meets the viscosity stability criteria very well, for very little cash.  Only on more modern bikes will the fork oil serve better -- that is, be worth the money.  Unless, of course, you are a suspension expert -- supposedly, the fork oil performs better, but I can't tell the difference.  Cheers!
