Yesterday I was out riding. I noticed that my oil pressure light was on. I shut it down, but I was out away from anything. After a couple minutes I started it up and still no oil pressure. I again shut it off. I was trying to decide if I was going to have to walk it back or what to do. I thought give it one more try, so i started it again. This time the oil pressure light went off. Keeping an eye on it I rode it home. This morning the light out just as soon as I start the engine. What should I be checking? There is plenty of oil, It has been a couple months since I changed it, the filter is tight no leak there. I don't know if it is safe to ride it or not. Is there any thing else I should be checking?
