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.

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 sliding |
When Maude (the Eldo) still has its drum front end, I used the |
| generic straight-viscosity 50-weight motor oil I could find. That |
| meant generic oil for Harleys, since almost no other group has used 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, |
| There are no small damping orifices in it, just a crude forcing |
| the oil really does is lube the parts, provide some "damping" |
| viscuous drag, and retard bottoming action as the tube end nears the 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 and |
| cheaper. 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) is |
| in the heaviest oil you can find. In Seattle, 50-weight works pretty |
| but if I lived in Phoenix, I'd try 140-weight tranny lube (which is |
| equivalent to 70-weight motor oil). Hope that clarifies what I originally said. GF _____________________________________________________________ Want to find the best email lists? Check out the Topica 20! http://www.topica.com/topica20 |
