Reed Questions


Recommended Posts

I have my cages out and figured I might as well replace the reeds while they are out. I cant afford v-force so dont even go there. ;) My questions are.. Is there any way to tell if the stock reeds are wore out? Mine look brand new. If I replace them what do you recommend? I heard that boyesen reeds are good. Which set of Boyesens should I get? Can I port my own cages with a dremel? Is there much benefit in doing so? Any info or advice is certainally wlecomed. Thanks in advance

I'm running boyeson dual stage reeds. Improved my throttle response greatly....those stock reeds suck. I prefer the regular reeds over the carbon fiber. They flex easier and faster, tend to rip instead of break when they wear out, and burn up in the engine faster if they get into the engine.

I am running FMF reeds. I did have a brand new one break in half after about 5 hours of use. It didn't break completely, and was still there when I pulled the intake off. It didn't fly into the engine.... Which is a good thing. I haven't had a problem since. but, I wasn't running reed stops either....

If you look in the clymers manual, there is a spec to see of the reeds are bad. You measure the thickness of the reeds. I'd stick with tdr reed. The epoxy ones. They are cheap and work well. If you or someone you know has a dremel, port them for some more flow.

Pull the cages out, look at the reeds from the side and see if they lay completely flat against the reed cage. If there is a little gap between the reed petal and the cage then it's time to replace them. Sometimes you can flip the reed over and it'll lay flat for a while if you want to get a little more use out of them.

Carbon fiber and epoxy reeds are pretty good.

I'm not sure how the stock reed cage is designed, but if it has bridges in the cage, you can knife edge those with a dremel to smooth out flow a little. Also make sure there is a smooth transition between the intake manifold and reed cage (no mis-matched lips). Just picture the air flowing smoothly through the whole assembly and correct anything that will cause turbulence.
