Brought my 850xt in today to be looked at. I rode yesterday and put on about 23 miles. I used a half a tank and the fuel smell was horrible. The smell was strongest right by the pipe. I looked around the machine and didn’t see any leaks. But I noticed the clear tubes coming out of the tank had a small amount of fluid bouncing up and down the tubes. So I opened my gas cap and got a hissing sound and the fluid in the tube stopped moving around and disappeared in the lines. The machine never missed a beat the whole ride. So dealer called me and said my air filter was clogged. And that’s why the machine used up so much fuel. And it can also cause the bad fuel smell. As well as was fouling out my plugs. They said the hissing noise is normal. Does this sound right? I admit I haven’t checked my filter in a while. Shame on me.. anyway sorry about the long post. But thank you all for any help
