For now I’m going back together with my bike and going to put an air Stryker on it and I’m wondering if anyone has experience with both the vforce and boysen reeds. Right now it has an fmf fatty and shorty silencer with the 05-07 intake. I’ve searched but haven’t really seen anyone who’s tried both, especially on a cr. Also is it worth getting a whole cage on these bikes as with some bikes I’ve heard the stock cage with aftermarket reeds are just as good.
im also curious for anyone running the 38mm air Stryker Instead of the 36. How much did it hurt the bottom end since from what I’ve read the 02 came with a 36mm
I don’t have all the answers but in -02 i bought a bike from a european gp team and they used Radvalve on the bikes. They tried vforce to but boyesen outperformed it. I don’t have any numbers tough.
YMMV, but in my experience, reeds/cages/etc are mostly marketing baloney. I’m a pretty picky rider when it comes to bike setup, and I felt zero difference between stock, stock cage with Boyesen Reeds, and VForce cage/reeds on either of my 02 CR250s, one ported/head mods and one stock. I also felt zero difference between carbon tech, Boyesen, or stock reeds on my 01 KX250.
Only reason I’d do something like a VForce or RAD valve is if my engine mods guy recommended it to complement his mods, or if it came with the intake boot and OE was no longer available for an older bike I was fixing up that needed one.
Main reason I’m asking is because the stock ones are chipped so I figure why not throw something better in it if better is available. That’s the main reason I was wondering if the cage was worth it vs just getting aftermarket reeds
I would go with the rad valve just on the fact alone. The oem rubber carb boot is discontinued. The rad valve is alloy with the boyesen boot. Which is kinda universal. So will be available longer.

Oh, gotcha. In that case I’d go with what you can get. I touched on it, but SmokinJoe explained it better-the RAD valve is a great option if you need a new intake boot (Honda calls it an “insulator” I believe) and it’s no longer available from Honda and/or will be hard to get in the future. At least some (if not all) of the RAD valves cast-in most of what would be rubber on the OE boot, then use a straight section of tubing to connect to the carburetor. You’ll be able to find something like silicone coupling for years if needed to replace it rather than an obsolete part.
My whole point is that in my experience, I wouldn’t spend the money to merely swap out to aftermarket reeds and/or cage looking for a performance gain, but I’d certainly entertain it for the other reasons above. As I recall, Boyesen reeds are/were cheaper than stock as well.
Only difference I’ve noticed was better durability going with carbon fiber reeds. They didn’t chip as often. Didn’t notice anything in regards to better performance. I tried both, V-Force and, Boyesen on an 01 CR 250 and, an 04 CR 125. I’ve always been more focused on durability and, reliability anyways.
