I have a 2004 Honda Rancher 350 with a big bore and high flow exhaust I just put a bigger slow jet in to get it to idle but it doesn't run right when you give it throttle. With the high flow air filter off and the air box open it runs great but as soon as I put it back on it doesn't get enough air. The air mix screw is 4 1/2 turns out. Any suggestions on how to get more air through with the air filter on?
