Fork Springs Comparison (Picture)
 
Here is a visual of the stock '09 front spring and its HyperPro replacement.
Terrific upgrade. Really improves the feel of the bike.

Surely.
I removed the fork tubes (after removing the front tire, brakes and fender).

Then I popped off the fork caps, removed the old spring (the left one in the picture) and dumped out the old fork oil.

I filled the fork tube full of 10W fork oil up to 120mm below the top of the compressed fork.

Installed the new spring (the one on the right in the picture) with the tighter winds toward the top.

Then I put the fork caps back on, slid the tubes into the triple trees and re-installed the front wheel, brakes and fender.

Today's ride told me that I did the right thing. I really like the way it feels now. Much less sag, stiffer, yet not stiff, less nose dive while braking and the front tire feels more planted. Both on and off road.

What was the rough cost of the springs? :evil

If I get a set, I'll do what they say, but I'm trying to figure out why it would matter which end of the spring went up? :lol3

Long story on the springs. I bought mine off eBay. Thought I'd save a few $$. But it turned out to be more of a hassle.
So, if you see the front spring kit on eBay for $185 and they say it sips f of NYC. Beware. Mine came in from Italy...by-way-of St. Petersberg Russia. Seems my springs were sent to Russia, and I received the Russian dude's Honda Hornet springs.
Normal pricing is about $225 (or so).

Agree on the spring orientation. I'm always about following the instructions though. I figure they state certain things for a reason and have (hopefully) tested various options.

For hyperpro give Klaus a call at hyperpro USA. He is great to deal with and I personally much rather support a true shop rather than some computer on eBay. And he ships from the good lo USA via jersey. Not Italy through Russia.

A German Enduro magazine compared some springs available on the market.
Íhlins (linear), Hyperpro (progresive), Wilbers (progresive)

Wilbers got the best results in their test

Also they mention a Italian supplier for catrrige kit which I didnt knew before, it MUPO

Theoretically - as the coils compress they no longer function as a spring. Having them at the top means they remain as 'sprung weight', supported by the coils underneath rather than the dreaded 'unsprung' weight.

Or at least that's my educated guess...

I emailed the above company to get some more info on it including the price.... So far they responded that they have one US distributor here in California but not much else. Waiting on a reply, but a quick search turned up Lemick Racing. They don't show the cartridge kit for the 800, so Ill update when I hear back.

My local bike shop (and suspension specialist) quoted 985 Euros for parts and 210 Euros for labour & consumables
