As noggy says, support the weight of the bike before loosening anything. Easiest if the front wheel is still touching the ground otherwise you'll have the opposite problem and the forks will drop but that's not as problematic as the entire bike dropping

A simple trolley jack should suffice with a bit of wood to prevent any scuffing of your bike / exhaust Can use axle stands on the frame if available (not sure on the mounting points of the FZ1 I'm afraid)
