Waaaaay back in 1972 the dealer told me to drain the "fish oil" out of my Suzuki TM125 forks....and put ATF in it.  The dealer did not carry any special "fork oil", and living out in the country there was nothing else available but ATF.  It seemed like the perfect thing to use as it was a thin oil, it had anti-foam and seal protecting additives, and it was cheap and plentiful.  I am not sure any of those qualities has changed, and as far as I know it works just fine in forks.  I would guess that factory race teams use something else.......but I and my machine are not sophisticated enough to realize any difference.

Bill,

How many little cans of 3-in-1 oil did it take?

People say we pick on Bill, actually he jest begs for it sometimes.

Think of some of his "statements" as being a cricket cast in among the lilly pads.  

He knows there are bass in there ....  he just wants a hit, doesn't have to be a big one, just a hit.   A small mouth or a crappie would do, or even a yellow belly bream.

He casts, then he watches his bobber alertly for any action.

Then he gets a nibble ....

Lightweight forks get Dexron 3. Decent sized forks get Type F. Real forks use grease (springers and girders). Can't wait to replace my bike's piece of junk glide front end with a springer.

If I had a bike with a tunable fork I'd be buying BelRay fork oils and experimenting until I hit the right one(s). Some forks need the oil custom mixed to optimize performance.
