So I have a few question on fork spring pre load. I have a set of cone valve forks for my 19 250sx (black version) I don't know what cones are in them or what spring rate... they were shipped to me and were suppose to be valved and sprung for 170lbs.
Now my issue ive noticed is the bike is diving hard and I can basically buttom them out easier then I think a "a kit" should. my last ride was on a track that got complete destroyed and ive got my compression clicker dialed all the way up to 2 turns out (from max). I noticed today you can adjust pre load on the forks externally so I checked it and they are set at 0 preload (0 clicks).
so I guess the question is could this be causing my soft front end issue> ive read should be around the 4mm area of pre load??

Adding preload compresses the spring slightly when forks are fully extended which is going to influence the front end sag

More oil gives a more firm feeling overall.

So go to 420 and go to 10 on comp. Whats your rebound at? Should be around 16. If bike is unbalanced and low in front, add 2-3 clicks of preload. Then you can fine tune last with with comp clicker.
If still to soft, you might have float on the cone (should be zero float on standard setup). Or you dont have the red cone (yellow is Enduro, Red is MX (standard), blue is firm MX/Light SX and black SX).
Even cone spring could be to soft. 25nm cone spring is standard, 50nm a bit firmer, and 75nm really stiff.
Or simply it is just valved to soft. Springs in fork has to match with rear spring of course.
