About a month ago I was riding my bike and water was draining underneath my bike while I was riding it. I took the fairings off on the left side and found that the coolant bottle was empty and the hose that was nearest to the cap to the coolant was led to the bottom of the bike. When I filled the bike with water where the coolant goes There was no leaks. I let the bike run a few minutes and the bike was not overheating, so I decided I take a slow ride around my blow. The first few minutes the bike was heating normally, until I started to get on it and thats when the temp meter showed it at half way point. However, there was no water leak like previous time. Does anyone know what could be the issue?
