dont buy them. My cousin added added V-Force 3 reeds to his 01 edge-x 600. absolutely zero difference, and we tested them with a radar gun, by personal feel, about an hour apart, in the same place. ZERO difference.
My recommendation is to only buy them if you need to replace your stock reeds. Other than that they are not worth it. Sometimes you get a little better throttle response, but without further engine mods you will not gain any power with them.
I have Boyesen Rage Cages on my 2002 Doo Renegade 700, but that's only because my stock reed setup was ripped and pretty much done. I went aftermarket because I got the Boyesens for slightly less than stock Doo stuff (or about the same - was 1.5 years ago).
take a look at carbon tech reeds and utilize the stock cages. affordable, great replacement for failing stockers and you should notice a gain in performance and mileage. or go all out for the boyeson rage cages if they are available for your sled. money well spent, if you can afford it.
