Dudes-
I've never tried anything that heavy in my lever shox, but way back when I
tried 90w in the forks of my Kawasaki 125 Enduro when I decided it needed a
lot more dampening. Result -- blown seals. Oil that heavy has a tendency
just to "go around" the seals and foam like heck. Result, not much
dampening, not for long....
Anyway I just sent J.K. Jackson's lever shock suggestions to another lister.
Here they are for the benefit if the entire list:
"Use stock Armstrong levers - there is an adjustable valve under the large
plug. Tighten the nut at the end of the valve all the way down and put a
.070" washer under the spring. Refill the shock with 30wt oil (he means M/C
fork oil) and bleed all air from the shock before you put the valving and
the large plug back in."
>From what I understand the valve only affects bump, not rebound settings.
The heavier oil will help with rebound. The Harley 50wt is probably as heavy
you should go.
These suggestions appeared in a Grassroots Motorsports article "The RxFiles"
where a TR6 was the subject. (Mar/Apr 97)
I've actually read about people "remote gas pressurizing" their lever
shocks. By adding a line fitting where the fill plug is, and adding a
motorcycle style gas or air pressurized reservoir. A few PSI of air or gas
pressure really helps the oil from foaming and the increased oil volume
helps keep the oil cooler in long events. I guess your oil seals would have
to be in really good shape!
