Your fork springs are too soft to support the weight of the bike
I think the 900 has dual rate / progressive springs - ditch them and get linear rate springs such as K-Tch or RaceTech
The 2002 model has dual rate
6.86 N/mm (0.686 kgf/mm)
9.32 N/mm (0.932 kgf/mm)
Initial rate of 0.686 is way too soft and hence results in the huge amount of static sag
second rate is too hard and is why you only get 10mm of sag when you sit on it
you want something like 0.85kg/mm linear rate springs
your sag figures for the rear suggest the spring is a little hard for your weight
Messing with the preload will only result in both figures going up or down together, the gap between them will stay constant
To change the gap between the 12mm & 30mm requires a different spring rate ie new spring
sorry can't help with the fork protrusion out the top of the yoke
Have you downloaded the WSM?
2002 model has fork top flush with the top yoke
