Brought to you by Holsten Premium, I give you...
new forks!
Damn, that was a long project. Between stripped threads, mis installed spacers that had to be removed (from under the lower headset bearing), broken threads, seized forks because i don't know how to install a wheel on an inverted fork, it's been a slice! Time to give them a gentle breaking in tomorrow. I still need to figure out something to stop them from hitting the rads and gas tank before hitting trail. Good times in the basement!
Here she is stock.
Here's the spacer I machined. Same as others have posted, but a toleranced drawing for the discerning machinist.

Mine hit the gas tank, I'm not really worried about it at this point

well, they sure are stiff! My research says I have the right stock spring (stock is 0.47 and racetech recommends a 0.472 for my weight and riding)
Took it for a spin on a rough gravel road with lots of rocks. Riding slowly, the fork barely moves and I take a beating. Once I speed up to 3rd, it starts to soak up the hits, but is still quite harsh.
The valving is still stock (main valve still has the threads peened).
I'm planning modifying the shim stack - got any suggestions for the DIY with little to no budget to modify them?
175 lb + gear
slow/medium pace woods (lots of rocks, roots and slow tech) riding
I've made a plan based on a guess and a day of web research - need some ideas though.
Stock (assuming an 09 is the same stack as my 06)

Here's a cute graphical representation I made up to understand the stack.

I'm also going to ask here... No need to duplicate your answers. I hang out here way more often, but there seem to be many more tuning gurus on TT.
