Intro? Yeah oil is nice and clean. Was going to change it but was advised it would be ok as oil doesn't really go off

Thank you will do that. Any ideas on the oil pump?

Thanks all will do as suggested. One more thing .... now that the water has circled the engine a few times it is really black and shitty, guessing because it's been sat to long so thinking of taking off bottom hose to flush it out then refill it. Or am u running the risk of giving it a air lock? Also I'm taking it for granted that the oil pump is working, it smokes a bit when she starts and seem to be running fine so safe to say it's working?

Yes water level is still full and rad was hot

Ok just took it on another run and water in the tank is hot so I know the pump is working and this time the light didn't come on. Could it of just been a stuck thermostat that has now unstuck itself after a run? And if the pump is working so the engine is getting water to cool it can it still overheat? Like if the warning light comes on but I know the pump is working should I worry or just put it down to a faulty light?

hi all and thankyou for reading... ive just bought a 50cc 2003 aerox that has been of the road since 2004. filled the header tank up which took barley anything, i thought as i was filling it the coolant would go through the pipes but it never just filled the tank. road it today and the temp light came on, all pipes are hot but water in the tank isnt hot at all. could the pump be nackerd or just an airlock? and is there a bleed valve on the head? PLEASE HELP!!
