i am trying to setup the suspension on this new bike. Taking measurements of the static sag and rider sag I have big difference between front and rear. The rear had static sag of 5mm and rider sag of 30mm which is around what is standard but the front has static sag of 37mm and rider sag of 42mm which is too soft. I have adjusted the preload but makes little difference. The first step I was going to do was change the oil and make sure the level is right. Could not enough oil cause this problem or could it be somthing else. I dont think i need a firmer spring because i only wiegh 76 kg and the rear is fine.
