I paired the reeds with new FMF pipe & R304 shorty on a 2014 YZ125 I bought used. Everything runs great but I never road the stock reed valves so don’t know how it compares. But I am happy.

I have always ran the Rad Valve on all my bikes. Never been disappointed! Bolts right on every time. I’m a dune rider and makes that 2 stroke sing!!
Great 2stroke performance part. Great for all around better performance.
Should be noticed especially on bottom end, holeshots and cornering. I would recommend a rad valve to anyone thinking about it.
The rad valve was exactly what my 2006 Rm250 needed. My stock intake was dry rotted and needed to be replaced so rather than spending the money on a new OEM part I went with Boyesen. The bike runs so much better now from the bottom to the top. I have no hesitation at all, just quick, crisp revs. It also made the hit of the power band more predictable which helps out a lot on the track. The product comes with everything needed to install including an intake gasket, intake coupling, and clamps plus they give you detailed instructions and suggested jetting settings. I will put one on every 2 stoke I own!
I've always been a big fan of the Boyesen Rad Valve. This is my 4th one and I have no reason not to keep coming back. There is always a noticeable performance boost and the fit and finish is great. The housing is tough and the reed petals hold up as long or longer than stock and/or other brands.
I decided to try out the Rad Valve on my Rm 125 and am very satisfied. Being very sensitive to Jetting I had some concerns. It seems like the consensus is that the Rad Valve requires more jetting changes then the V force but is potentially a better mod. I believe this is true. Although I noticed an increase in performance right away. It became more noticeable when I leaned the main out a little more. The Rad Valve improved performance all over the Rpm range.
Will it make you faster? Probably not.
Is it worth the money? That depends on how much money you make and if you know how jet your bike. (MXA's secret jetting specs is a good place to start.) Or the FMF website!! =)
Will I Install a Rad Valve on every 2 stroke I own from now on. Yes!!
Excellent performance as always.
