New fork internals?

[breakdown]

Now that my bike is parked for the winter season, I'm already starting to think of what I can do to it over the winter. I have a full Termi system and new mirrors planned for sure. I've been thinking about maybe looking at a 25mm valve kit for my forks.

Has anyone done this yet? How did you like the end result?

I haven't done the valve kit yet, but I just did a spring change to correct springs for my weight and what a HUGE difference it makes. Doesn't feel like it needs any valving done now as it handles like it's on rails.
Eventually I might do the 25mm carts but for now I don't see the need.

How much do you weigh?

I'm about 175 with my gear on and my mechanic said the stock springs are fine for my weight. I'm questioning the quality of the fork springs. I may go with a set of Ohlins springs for my weight and see how that works before I get into the cartridges.

Where do you get the springs and valve kit?
Thanks

I weigh 200 geared up and got my springs from RaceTech. They told me that the stock springs are .60 Nm and for my weight they gave me just under .80Nm springs. By the way I have the S model if that makes a difference.

I had the preload all the way in on the stock springs and only got 49mm sag. The shop I got my forks done at have many connections to suspension gurus that said to have about 37 to 43mm preload. I set mine at 43mm and it worked flawlessly at a track day and got rid of all twitchyness. Didn't really need a steering damper either.

So they increased your spring size?, I have thought about decreasing my front springing to get better sag and make the forks more supple, the compression damping I find too harsh so I am gonna put 5w oil in and looked at dropping the spring strength to help.

I am basically the same weight as you, maybe slightly lighter a a coupla kg but that would be it.

Do you have more tech specs on your springs, length, wire dia etc and also what did your new ones cost, many thanks Andi

I did mine the first week I had the bike, Tony at race tech (951) 279-6655 changed the valving in my shock and installed the 25-mm kit. I am setting up bike for Pikes Peak, they did Greg Tracys bikes and put the same settings on mine. I found the valving to be to fast for sea level. Apparently hi altitude makes a big difference so call him and tell him where you are going to ride. We are going to add a couple shims in the front, Tony is great I looked at all options and this was the only one available.
This is a great way to go - they are completely adjustable plus you can take them out if you sell your bike and install in your next bike.
Let me know if you have any questions Wlloie

MonstaMan, do you have the S model? The stock springs on my S marzocchi forks were spongy and weak...perhaps I had a bad set of springs??

I ended up staying with the stock 7.5w oil in the forks and the bike is really smooth. I've heard a lot of guys saying that the stock weight oil and springs are too stiff, but my bike was the opposite.

Dan Kyle explained to me that just because you achieve sag on stock springs doesn't mean they are correct and actually end up making the suspension harsh. I wouldn't go to a lighter spring than stock.

All springs from Racetech are $109, but I had mine made same day(none in stock) and had to pay an expedite fee so I can finish the bike before the track day. I'm really happy with the results.

I am with you on the too spongy opinion. I am 265 with full race gear on.
