Apologies if I sound a bit thick. I started my GasGas450 this morning to check it was Ok - did the usual chain, air filter etc. It started fine ticked over for a few minutes so I stopped it. Went to ride this afternoon, tried to start - when I turn the key the oil pump does not fire up. tried several times - no sound from the oil pump. Bike turns over ok. I have checked the kill switch, ingition, connectors, fuses as it feels like an electrical problem but no change Any ideas what the problem could be? There was nothing strange when it ran earlier?
