    Oh yeah. Brap!

    Fits my yz 450 air box good. Use filter grease! Remove back fire screen and secondary filter when using this. More surface area and better filtration. K&N! Lasts a lifetime, literally

    JD Jetting Big Win

    I buy ALOT of products and rarely write reviews. Something has to be either really terrible or really good for me to spend my time letting others know what kind of product they're looking into buying. The bike used this kit on had a very poor running condition when i picked it up. It wouldn't idle and would backfire like crazy when it wasn't choked. I knew this meant an extremely lean running condition or a vacuum leak. The air-box and intake boot looked good so I moved onto the carby. I stripped the carb down and cleaned all orifices and jets. The carb was a little varnishy so I thought the good clean would correct the issue... I was wrong. The same symptoms of a lean running condition persisted so I bit the bullet and ordered the jetting kit after reading countless replies on various forums that the JD kit would most likely solve my issue. They were right. The kit was super easy to install and came with fantastic instructions and explanations to ease install. The job took about 30 minutes to do and after the kit set on the recommended settings was installed the bike ran great. My only complaint is for what it is the kit seems a little expensive but I would buy again and I would recommend to friends running older carbeurated 4strokes.

    I would not purchase again

    The filter looks well made but doesn't fit very flat in air box. It still works but doesn't inspire confidence or trust.
