XR 400 springs in a KDX200

[andrew]

G'day blokes, just after a bit of advice here. I am planning on putting a set of eibach fork springs into my 1996 KDX200.
I have ordered the XR400 units, as Eibach don't have a specific listing for the KDX, and I have been informed they will fit.
My old springs are 470mm long, but the new ones will be 510mm.
Can anyone reccommend what preload I should use??
BTW, new springs are .41kg/mm; I come in at 75 - 80 kg, and I do mostly woods riding, enduro & pony express, and a little bit of natural terrain MX (no big jumps). I am a medium - fast rider.

Thanks for all your help !

Cheers,

Anywhere frome 80 to 120 MM. R.C run's something in the range of 120.
The lower the number the better the bike will steer but will lose handling and you can get headshake. The higher then number ( more pre-load ) the worse your steering will be but your handling will be better.
Most people start with 95mm And go from there to set to your like's.
