Just wondering if my water pump is starting to go. I loose coolant in the overflow resivor after about 200 miles of rideing. It drops from the max to the min lines, but does not ever go below the min. Checked the raditor cap and all looks fine, cracked the bleeding cap on left side and coolant comes out. No visible leaks in the system and no puddles of coolant after sitting for the night. Just changed the oil today and no coolant in the sump or crank case. Any thoughts out there?
