    Jason in OH

    Crisp bottom end

    Along with rejeting this jet is great. Put it in my 05 yz250 after the air got colder here in the northern states.

    Keihin 99101-116 Series Main Jet

    Jason in OH

    Great for re-jetting on 2 strokes

    This jet is strong and can be taken in or out with either a flat head or socket. Which makes it easy to rejet the carb without taken the carb all the way off.

    Works good

    I needed a jet so I purchased this one. It fit good and seems to be the jet I needed. So far so good.

    Keihin 99101-393 Series Main Jet

    Caleb in MN

    It works.

    This was for my 2002 XR100. It came in a plastic bag with no instructions, but if you need help installing it it is very well laid out in the owners manual. The price was fine is it worked, so I would recommend this.

  • Keihin Air Cut-Off Valve Set

    Keihin Air Cut-Off Valve Set

    Stephen in WA

    Nice

    It didn't 100% resolve my back firing issue when I let off the throttle, but it greatly reduced how loud and how much it was doing it. The OEM cut-off valve was corroded and brittle so I'm glad that I replaced it. Installation was quick and easy.
