I was riding on my GG today. Before I took of I checked the oil level and everything was alright. When I had ride for about 4 miles I noticed the oil light started to flash. It did not shine bright at first but I stopped the engine immediately. I checked the oil but everything was ok like before. So I started the engine again and oil light was off so I thought maybe the sun did shine on the glass and it was a mistake. But when I had ride for about 3 or 4 miles it happened again so I stopped and did not start the engine again. I checked the oil level again and like before it was ok. So can anyone tell me what it is or why it happens?
