The manual for my '74 Honda CB-750 says to use ATF in the forks.

AFAIK, it's about 7 wt. I usually use 10 wt in my Hondas.

Why not? It seems to work for the rest of us. I mean, look at Dan.
He doesn't even have to *try*, to post and look stupid ;~).

I just bought an '84 Honda VT500 Ascot, and I need to replace the
fork seals. My question:
What SAE grade is ATF?
My manual calls for ATF as fork oil. I would prefer to use one of the
bottles of fork oil that I already own (PJ1 SAE 5 wt, 10wt, 15 wt.)
Do you have any idea?

ATF stand for "Automatic Transmission Fluid", and it should be self
explained where ATF oil basically is intended to be used.
As ATF oil is classified as a special oil and manufactured according to
a specific standard, you'll normally not find ATF oil in various grades
like regular motor oil and similar.
BTW, it's the first time I hear about using ATF oil as fork oil.

Not that unusual. The factory called for ATF in the fronk forks of my
'73 Ducati T/S, and I've heard of it being used in a number of other bikes.
I seem to recall that ATF is equiv. to ~7-8 wt. oil, but don't quote
me on that.

My brain cell came up with an indistinct memory of 7.5. My
experience has always been that I preferred heavier oil than the
manufacturer specified, so I'd suggest using 10wt for a start.
I did find http://www.albina.com/fuel/atftftf.htm where they mention
10W-20 and 15W-30 hydraulic and transmission fluids, but that's for heavy
machinery. They don't give a viscosity for automotive fluid. I found a
lot of stuff on "Alcohol, Tobacco and Firearms", too...

Well, since the original poster was from Idaho, I'd think that info on the
ole J. Reno's jack booted thugs might be useful.
How well does transmission fluid burn? I've got to get my malatovs ready.

told). If you go with the ATF and need more than one bottle, mix the
two together first, then fill the forks. Don't forget that disposable
plastic baby bottles are good for measuring the amount of oil, the graduations
are even better than a measuring cup.

Very common actually.

Possibly the anti foaming qualities. And its SAE 20 weight if you
want to believe the spec.

ATF is a cheap-ass lubricant (with appropriate performance), and its viscosity
is not very well controlled. I think ATF is supposed to be around
5-10 weight, but I am not sure. Proper fork oil is superior, and is the
thing to use.

These days, yeah Stig, but 20+ years ago that was the stuff to use
Ray or Emily Brooks
In a past life as a motorcycle mechanic [ not technician please ] we
considered Type F ATF to be equivalent to 9 wt. Whether this was bs I can't
tell you. In another prior life as a car drag racer we always ran Type F [
Ford ] in GM automatics for a harder shifting trans. Use 15 wt. fork oil .
