[QUOTE="i_955, post: 949905, member: 57722"] A valve of any kind is a device that restricts flow. In an exhaust port it is closed (not completely of coarse) during low pressure, or low RPM. As the rpm increases the valve is forced open by the air pressure (or other mechanical means) until it is fully open at max RPM. While the exhaust valve is closed at low RPM it generates back pressure which aids in the engines ability to expel the burnt exhaust gases efficiently. The end effect is a more controlled burn at lower RPM, giving a more usable spread of power or less of a “hit” when the motor finally gets on the tuned pipe. I personally would search for a bike with a power valve. But I’d search for a bike with modern suspension long before I’d dode up for a power valve equipped on. Unfortunately all modern suspension equipped bikes come with power valves. I think that is mostly correct. :cool: Good luck. [/QUOTE]
