    So a piece of grass gets past your airfilter? How that happens is a mystery to me, i always check all clamps and hoses prior to riding, but anyways... The piece of grass gets sucked into the carb, and through the valves into the combustion chamber. Your saying that when that happens the piece of grass it gonna make it down past the rings and into the lower end? I dont think so, it will get blown out the exhaust ports probably and never to be seen again, if it wasnt burned up on the combustion stroke. The only way that you can actually get "grass" in your oil is a breather line or the idea that it actually is clutch plate fibers.

    just my .02
    Maybe you're correct on the way it got in, but it was on my oil screen. On more than one occasion I found grass clippings in my stock filter as it was needling through the filter. That's why I figured it got in through there.

    I also never figured out why they didn't make this a sticky . There are many that didn't know about the screen until they saw this thread. Hell, there are dealerships mechanics that don't know about this screen. Definitely good preventative maintnance.

    Thumbs up

    Where any of these issues corrected in the newer models? I just bought a 08 and am pretty curious about it. More so the cam guide and chain than anything. Cleaning that screen seems like an easy job.

    i dont have a pic right now but i can. the line that goes to the bottom of the oil tank is the one with the screen. you will need to stand the quad on its @$$ and take the line out of the tank. thats the easiest way to get to it besides taking off the tank.

    If there is a measureable amount of stuff on that screen, be worried. Under normal wear you will get a piece here and there but normal is not to have the screen covered. If my screen is covered like that (never has) my motor is coming out and the cases are getting split. Pulling the screen is a good idea and it will improve oil flow but the real issue is seing what and how much is on there.

    I have had my YFZ450 from sept 06 and I have never looked at this screen. I change my oil/oil filter every 10 hours and I clean my UNI after 2 rides. I just did an oil change so Iam gonna wait till I do another oil change to it. I have about 70-75 hours on my quad give or take some. So what do I clean the screen with. Thanks
