HELP PLEASE! I just bought this ATV Friday road for the first time today. After about 30 minutes the bike back fired a couple of times after going thru some water maybe 6inches deep and died. It wont start sounds great as far as the starter and fuel pump and has compression? plug wire at plug has small crack dont know to do. There is a display code of EC42 and EC43? any one have any clues???

My concerns are about the water. Although it shouldn't be a factor, it could be I guess. I don't know where the intake is on the cats, but have you checked your filter, oil, etc?
