For fork fluid, Honda recommends using ATF. Make sure you buy ATF TYPE F which has no friction modifiers that can shorten the life of your seals. If you wish, you can also use any available 'fork oil'. It's more expensive than ATF, does the same thing but, you can buy it in different weights. ATF is approximately 7.5 wt. so, you should by a fork oil of comparable weight. But remember, the heavier the oil, the greater chance you have of blowing out your seals so, be careful.

First photo: To fill a dry fork (meaning, you've just rebuilt it with new seals) use 6.6 to 6.9 oz. in each tube. (You can 'over fill' a bit to stiffen the ride but, that will lead to shorter seal life.)

Second photo: If you're merely draining and refilling due to maintenance, use 4.7 to 6.1 per tube.

Your owners manual should tell you how much fluid to put in your forks. If you don't have one, they're available on eBay, either in original form or as reproductions. This procedure is also covered at length in a shop manual. If you don't have one, here's a site where you can download one for free.
