I'm with Paul. usually around 30/32, a bit lower at the track. It definitely feels sketchy when the front is down around 24. Would you let us know how you get on after you've tried them pumped up? I can't think of any time I've felt my bike tramline or the front slide, apart from a brand new tyre incident and once or twice at the track, fooling around with pressures. What tyres you have on?
I think you're right about Indian figure vs the Real World. They'd be looking for a comfortable ride as they thud along looking for MPG's. Cornering ability would have very little meaning to them.
I can turn my springs by hand too, when the bike's on the centre stand. I haven't as much preload as Paul, 68kg here.
