Maybe you have a similar problem to my 1150 then - the ignition switch was jiggery.
Turn on with key: lights came on, neutral, oil and charge lamps lit, no fuel gauge but clock running and showing perfectly good time. No fuel pump hum, bike would turn over but not fire up, due to no fuel pump.
Turn on and off a few times and rattle key fore and aft a bit in the key slot (jiggle it about) suddenly LCd fuel gauge would light up, fuel gauge turned on and pump hummed. Press starter, fired up immediately. Clock reset itself.
It urned out to be the actual ignition switch, which sits underneath the ignition key barrel and has the wire with white square bit showing coming out on left hand side - it is held in by one screw up the middle from underneath and has a length of wire about a foot long on it with a red block connector on the end. Once changed everything works perfectly again - the connections inside the switch corrode so they don't have much left to make contact with. It is a white plastic, round unit with all the connections inside. Not cheap, cost me £85 for that plastic switch.
