Hi. I bought a 2008 ultra 250X with a spin crank bearing and water in the oil. I rebuilt he engine and ran it for about 10 minutes when I noticed water in the oil again. I did notice when i tore it down a cracknin the head. I saw a kawa video where the crack I have is ok. Any idea where else water can be getting in? I also inspected the cylinders and donít see damage.
