Over the weekend I was riding (02 yz426) in the mountains when I came to what I thought was a shallow creek. I punched it through in 1st only to get to about the middle and be completely submerged up to my neck. I excelerated all the way through and the bike never stalled. I was at least 10 miles out so no matter what I wasn't going to stop and check it out. When I got back I checked the oil and it looked fine and the air filter looked and felt fine. The next day the bike ran fine? Can these bikes take that kind of thing? I thought for sure that I had done major damage?
