went riding this weekend and everything was going good we went threw a little puddle by now means anywhere close to being sunk or even stuck but after i went threw it the ole 570 started to idle a little high and then shut off..i started it back up and noticed that it was still idling funny and then it died again would crank but not start….we towed it back to camp and checked it over started with the checking air box and filter and where it goes into the motor and nothing in there just some dirt in the air box but nothing where it goes into the motor then checked the spark plug and replaced it anyway just to be sure still nothing i put my hand over the air intake and it felt like it had plenty of good compression the only thing we were able to get out of it was backfire a couple of times…i have the extended warranty and it is going to the dealer i was just wondering if any of yall might have an idea and if it is going to cost me a kidney to get fixed thanks in advance
