I just read the website touting the claimed benefits of the Scarey Fast Power Now plate.
I reminds me of the now-infamous Cyclone intake insert sold for cars/trucks that supposedly "turbocharge" the intake air.
Placing a restriction in the intake tract helps power???? Yeah, right.
I'm with those who doubt this product's validity.
Pathetically, there are riders/bikes that can benefit from a smaller carb! Just do not try telling its a great power improvement, or a magic jetting tool. Stick the contraption in front of your mouth, talk through it, and tell me how it splits your voice? Splits the pressure wave, not happening. Lighten your bank account only. Pretty sure you could accomplish the same detuning by modifying the airbox lid, and jetting it?
