I purchased Eton about 2 yrs ago and have had a lot of problems with it. For one the airbox is like behind the engine and impossible to get to!! Second I dont know how to fix my brakes they suck and dont really work anymore. Also the steering is messed up when you turn left all they way the tire rubs on something and doesnt rotate. Also when you drive straight the quad turns to the left I believe, and I cannot find what is bent. If you guys have any solutions for this japanese machine please let me know. It is basically beaten on its been flipped teice always hits trees but most of this is because of the poor steering/brakes.

 

I'm assuming your talking about the Yukon 150? Sounds like you've got something bent in the steering,possibly just a tie rod or maybe even an A arm.Turn the tires and see where the tire is making contact.It should be pretty obvious what the problem is.Are the wheels facing straight ahead when the handlebars are straight?You may need to get a manual and set the front end alignment to the proper specs.Can't comment on the air filter since I have no experience with the larger E-ton.
