my coolant is super low every time i check it. Last summer it used to stay up around the top of my radiator so i could still see the coolant but for the past few weeks its super low and even when i lean my bike way down i cant see it, i fill it up every time its low and it takes a lot I don't think that it is being blown out because it never gets hot, I can always hold my hand on my motor for a few seconds whenever i stop. I've checked my hoses and I can't find a hole and none of them are loose. I haven't changed my oil yet to look at the color but it doesn't look unusual through the sight glass. Any idea what could be happening?
