I was riding in heavy rain this weekend and my low oil light came on- I just changed my oil and filter a month ago and have only ridden in town since then. Checked the oil level and it reads fine (full). Went out the next day and it went off. Tried again today and it came back on. ??? I've never cleaned the screen so maybe that's it? Clogged filter?
