I've got straight 70w motor oil in my Eldo which was a vast improvement
over the 10w and 15w fork oil I was using before. Especially when two
up. Much easier to change the fork oil than the fork spring spacer
which requires removal of the whole front end assembly. But I also put
in Moto Int. progressive springs to replace the OEM units - very nice!
Can't remember if I put in a spacer or not ... sure sounds like I'm
becoming a spacer (or space cadet)...

Hi Keith,
Here we have the classic "Goldylocks Syndrome". Without the spacers it was "too soft", with the spacers it's "too stiff", hopefully you can find the happy medium "just right".

Try going to a heavier weight oil instead of lighter to control the topping. Going heavier may make the compression damping a little more firm, though. I'm using 30w fork oil in my '69 Ambo and have noticed little difference from the ATF the PO had in there. But then I was always happy with the way my forks worked. They do top out, but usually only over railroad tracks, potholes, etc. or when I'm pulling wheelies (hah, hah!)

Drum-brake Loop forks are really crude - there's just a rod that goes into the hole in the nut holding the lower fork bushing in place to control bottoming and rebound seems to be controlled by nothing more than oil trapped between the upper and lower bushings at full extension.

I'm not sure what weight or type you should try - maybe someone else has a suggestion? In the end it may come down to replacing the springs to get total satisfaction. But that too has it's problems... Cheers,

Charlie.

 Bought 7 weight fork oil yesterday, will change fork oil soon. Has
anyone noticed a difference in dampning with different weight oils?
Should I remove the spacers from the fork springs? If yes, how do I get
to the springs?
