Had my 500 zforce out for the first time in the rain last weekend and when I got it out today I checked the oil and removed the plug at the bottom of the air box and was very surprised at the amount of water that drained out . We were out almost all day in the rain but with no water crossings or deep water holes . I run with a half windshield so I do get a fair bit of water in my face but even still I could not believe how much water came out . I guess that is all the more reason to do the snorkel kit I was thinking about for a winter project
