    Great Reeds

    Great reeds for the money. They did make a difference, but it feels like I will need to rejet to get the full effect. Also best price I have found on the internet.

    Beautiful piece of engineering!

    When I directly compared this with the stock reed cage, I was amazed at how much smoother everything looked inside! This is all one continuous piece of aluminum that looks like a ported cylinder on the inside. Very smooth, with knife like edges wherever it splits the air coming in. No funny ridges or places to cause turbulence during intake. It just LOOKS and feels like it will support more CFM compared to stock. With that said, I haven't ridden it enough or jetted it to comment on an actual performance increase.

    My bike has never run this good!

    I installed these in my '01 YZ250, just before my last hare scramble, and all I can say is WOW! My bike honestly has never run this good. It has so much more power, through the entire power band! Even better, it helped to smooth out the 2-stroke power surge, so the extra power is also more usable! At high speed / RPM, I'm not having any issues with reed flutter now. I can't say enough good things about these reeds! I won't ever run anything different.
