I have similar issues with my Fat Bob. The bike can clearly handle much better than the ground clearance allows. Why does Harley make all their bikes so (EDIT) low? I guess it looks cool but kills the lean angle. Best options are change out the rear shocks for taller ones, get a 2 into 1 exhaust that allows more clearance and use little stiffer oil in front shocks.
