I think there is a lot of info out there on this topic if you do a search.  Some folks use motor oil, others use fork oil at different weights (I use 10w), some use ATF, etc etc.  Also, I would highly recommend you purchase a manual for your bike so you'd have all this info available.  Definitely worth the investment!

Thanks, I have researched this but cant find any answers, thanks for the 10wt now all i need is the levels. ive got the haynes manual but it covers 400/4 and 550/4 and the forks are different on the 500/4. typical

The manual states 160cc's.

Honda makes a fork oil product. May not be necessary, but you probably can't go wrong with it either. There's also a different amount to add depending on whether you are just replacing what's been drained or doing a fork rebuild where all the oil has been removed. That's in posts here, too.

3/4 down the page. I've really gotten used to this method. It works awesome IMO!

It's ATF or fork oil. Motor oil is a no no.

The search function works great here. I just typed in "fork oil" and got lots of hits. Here is a recent thread:

You should be able to find the Honda service manual here for your make and model. It will give specific recommendations for all sorts of useful things to do with your bike.

I want to say that it takes 7 oz per tube. ATF is what is recommended. You can use different weight fork oils if you like. I my CB900F I run 20wt. It really comes down to what type of dampening you want. If you have the original fork springs running a little heavier fork oil will help to a point. But at some point you should replace the springs. There are just old and saggy.

Be sure that before you put the springs in that you pump the tubes a little to get the air out.

Here are the viscosity ranges for ATF:
