lr fork spring preload?

Does anyone know what Progressive specifies for the preload distance (not
spacer length) for the LR fork springs? My few neurons that are still
intact are saying an inch to an inch and a half; but then again I learnt
long ago, when I still had more that functioned ok, not to trust 'em...

I hear ya Steve.
You know, I'd be very interested in the same.
I had a Kawi shop install my Progressive fork springs last year. I
believe they simply swapped the springs without "resetting" anything, and
changed from the stock 10w to 15w, at my behest. Now, I noticed right away
that the ride was harsher. The forks were definitely stiffer, yet in an
unforgiving way. Seems to me these things need to be tuned. Or maybe just go
back to 10w?

Most forks need a slight amount of spring preload and it usually requires
that the spacer be even to just below the top of the fork leg by about 1/4".
This will allow about 1/4" to 3/4" preload once you install the top nut.
Preload is set to the riders preference. Adjusting spring preload will
effect ride height and every bike and rider is different. So I usually
start with the spring spacer to the top of the fork tube with the forks
extended and try it there. If you need less preload you can always take off
more of the spacer to have less preload.

Hmmm. Again, presuming I m still memorying ok, if I put the spacer at the
top of the fork that would give me 14mm of preload (the depth of the fork
cap based on this presumption of memory) and _something_ in my head says
that Progressive was recommending an inch to an inch and a half which is
certainly more than 14mm (I may not remember well, but I think I can still
do the math). BTW, it is hard to add to the spacers with a tubing cutter
;-].
When I put the LR s in, I m pretty sure I did it to whatever it was that
Progressive recommended, but I think I want a tad more preload than whatever
I put in there, and I thought they specified a range. I can just open them
up and measure what I have in there I guess, but I m still trying to verify
my memory against what the Progressive folks recommend.
I guess my question is "what does Progressive specify for preload distance
on LR fork springs?"

The Progressive Suspension LR series fork spring installation guide can be
found at:
http://groups.yahoo.com/group/DSN_klr650/files/Suspension/Lr-pfs.jpg
It states to set the spring preload from 1/8" to 3/8".

Nice Fred. Whydya think my springs are stiff? Maybe the spacing's wrong, or
is it the 15wt oil?. Does the spacing affect the springs' action? Seems that
the stock preload is already minimum (no spacer) preload, so it should be
softest, no?

sell your stock saddle?

Anybody have a stock saddle (my bike is 97) they want to sell? Condition
isn't that important as long as it's still usable. Please reply to
loumatts@..., less chance of losing your EMail in the clutter that way.
