Your welcome to attend, keep an eye on the post for a group meet up & ride down .

Yes I have 0.85kg K tech springs in mine, they are drop in using the standard spacers, I have 10wt oil and 140mm air gap, preload set to 25mm, forks dropped 5mm through, you need to drop front as the springs make the bike sit higher at the front (as standard they sag more), might go down another 5mm on mine for the summer.

hi popkat sorry but my bike knowledge is minimal how do you determine what weight of spring to get and just to prove my ignorance how do you set preload and what does it do

If your not doing the mod yourself don't worry about the details, it'll involve lots of typing
Pass on the info to who's doing the work as they will know what it all means. wait til the workshop day it'll be worth it and you'll gain some knowledge about suspension too..

How much do you Weigh ?, I ask because the weight of the best suited spring is determined by your weight. If you give me your weight I can advise which spring.

For your weight 0.85 Springs will be right for road riding and some track work. 0.875 -0.90 may be better for very fast track work and racing, but it's down to personal preference then.

If you get them set up as per my first post in this thread you will be very happy with them

Racetech's suspension bible is well worth getting if you're even half interested in this sort of thing. It's well written, in my opinion, and has great diagrams to help.

I assume that the "weight" of the Spring is its rate. It's rate is an expression of how much force needs to be applied to get it to move a certain distance. For example lb/in or kg/mm or n/mm etc. It's best to think in terms of force as opposed to weight. True, if you were able to sit on the Spring (oo er) and you weigh 80kg, then the force you're applying is 80kg. But fork springs compress under braking (or just riding along) because a force is applied, not, strictly speaking, a weight.

So a coil Spring with a higher rate will need more force to get it to move a certain given distance. Or to look at it another way, a higher rate Spring will move less distance for the same force.

Cheers.

Bear in mind you'll be doing the work yourself, with someone checking up and making sure you don't mess it up...
