I called racetech today and he quoted me at $340. I'm not sure if I want to spend that much right now as I just got a job and need to make payments on my college loans.
Hey - it may be not cool right now, but you are making the right decision to stick to paying off loans before throwing money into toys - good work! That said, if you can put ANY money aside during the winter you could do this as a winter project before it gets to be riding weather again.
I've got a 2011 WR and bought RT .50 fork springs, Gold Valves, and a .58 shock spring all for a little over $400. Although I have a decent garage and lots of experience working on cars and other stuff, I'd never taken apart motorcycle forks before. I watched a bunch of youtube videos and had the shop manual for the bike. The first fork took me a few hours (mainly because I had to fab a Cartridge Holding tool (looks like this: http://www.amazon.co...g=5336121818-20) as well as track down a 14mm hex driver/allen wrench to get the compression valves out (no place in my town had a 14mm, so I finally got a nut that was a 14mm size and welded it to another larger nut so I could use it with a regular socket), and the other fork took about 45 minutes. I wish I would have had the right tools for the job right off the bat, because this would have honestly been a pretty quick job. All of this to say that it's not hard and you can definitely do it yourself and save some money!
And yes, the Gold Valves and heavier springs front and rear make a world of difference in handling and what the bike seems able to do, both at high and low speeds. I went with a 115mm oil height with 5 wt oil and no preload spacers, but I'm going to revisit that with spacers (to adjust sag higher and bring me a little higher up in the stroke), and probably right at 90mm on the oil height (at the recommendation of RT) and possibly 7.5 wt, since if I really slap the front end down off a jump, it'll still bottom on the front. Haven't bottomed the rear since the heavier spring. Even though I don't have it dialed in yet, I can't recommend springs to suit your weight and a re-valve highly enough.

I'm about 200 lbs with no gear by the way.
