Boyesen Reeds
-
Does Boyesen Reeds give more power?
-
In a word, no.
-
Are they worth buying? Low rpm torque?
-
Power is not the point of uprated reeds.
If you want power, then you will want a variety of parts.
-
I meant like do they give low end torque or throttle response?
-
No, don't waste your money unless part of a comprehensive engine tune
-
Ok i will buy athena silencer because i need it.
-
Will drillin yeis bottle 2mm bigger increase hp?
-
As discussed in the other blog, the bottle works from resonance. So in a word no.
If anything you could harm performance.

@jonne123 Using Boyensen or carbon reeds will not add any more power to your bike, all they will do is provide a more responsive/crisp throttle. Reed blocks like VForce etc will also add this extra responsiveness and may also further enhance it, by reducing intake air turbulence too. You will not gain any more power but the bike will feel quicker due to a smoother power delivery.
I remomoved my YEIS bottle and lost acceleration and 10mph off my top end speed, just leave it alone and stick with it for best performance.

And i know that reeds give throttle response and exhaust changes the powerband and maybe gives little extra hp
