If my old eyes don't deceive, you have return springs on both front brake arms. Usually fitted on r.h.s. only, otherwise function of balance beam stop is negated. Maximum leverage of arms is just as arm and cable form a right angle. Keep your rear stand bolts and nuts (F69 and F27) fairly tight on their Thackeray washers, you don't want to set up any vibration in that tart-tray rearward of the seat, particularly if you have alloy guards. A pretty bike, enjoy it.
