What do power valves do?

[banji1218]

Hello there. I have a quick question. I think i pretty much have the answer but still would like to verify and clear it up. What do power valves do? I have a GP1200R and i notices it has them with the waveeater clips. Can someone please explain to me what exactly do they do? Thank You

They are closed at low rpm for better torque and they open at high rpm for more power. Basically, they give you a broader power spread.

They break and fall into the cylinder and cause piston & cylinder damage.

Hahhaa , i already got that covered with waveeater clips. I hear it works wonders!

they go against gravity and when they break they take gravity with them .
