Wow, that sounds really off. At one time early last year I peaked at 195 lbs. in shorts, so figure I was close to your weight geared up. Same '07 bike too. My 5.4 spring was set to approx 10mm and worked good. My race sag is about 110mm. Maybe your spring is not really testing at 5.4? Is that 20mm preload what it takes to get the bike to steer or to meet a certain sag number?
