I haven't used my CR250 in a long while but 2 weeks ago I put it my enclosed trailer to move it to an other location. It ended up staying in the trailer for 2 weeks but when I came by today I noticed a big puddle on the floor under the bike. After some looking around, it seems like all my coolant leaked out from a factory hole located under the water pump. However, the bike was never started, just pushed in the trailer. Can anyone help me figure out why it suddenly leaked and how to fix it? Thank you Here's a picture of the hole.
