Rich Z,This subject was on the list some time ago,and I just happened
to save a message from Greg Field concerning fork oil in Ambos and
Eldos. I have my front end on the Eldo partially apart to do the
maintenance thang....now if I can just some of the crap in the garage
rearranged to get finished up. Anyhow hope this helps.

use inGreg,
I have an early Ambo and a 72 Convert. What type of fluid do you
damperYOUR Eldo? Heavy weight oil?
Scott
I'm getting a lot of mail on this, so here's the answer for you all:
I use ATF because my Eldo has the disc-brake forks with sealed
cartriges (like your Convert does). All it does is lube the slidingparts.
cheapest
When Maude (the Eldo) still has its drum front end, I used the
generic straight-viscosity 50-weight motor oil I could find. Thatusually
meant generic oil for Harleys, since almost no other group has usedHydra-Glide
straight 50-weight for decades.
Remember, that fork is on a technological level with the Harley
fork of 1949 (and it's no accident that it bears a resemblance,either).
There are no small damping orifices in it, just a crude forcingcone. All
the oil really does is lube the parts, provide some "damping"courtesy of
viscuous drag, and retard bottoming action as the tube end nears theoils,
forcing cone on the slider. The result is that you don't need fork
with all their special anti-foaming agents. Motor oil works fine andis
cheaper.a set
The best you can do to improve the Ambo fork (short of machining up
of real damper rods for it or replacing it with the later fork) isto put
in the heaviest oil you can find. In Seattle, 50-weight works prettywell,
but if I lived in Phoenix, I'd try 140-weight tranny lube (which isreally
equivalent to 70-weight motor oil).
Hope that clarifies what I originally said.
GF
