One of my personal favorites , it has many interesting mods including a CR250 top end with factory power valve.

what does the power Valve do?

[3leggeddog]

a power valve is like a dam.it helps control the amount of air the motor can exhaust.with lower rpms it stays closed,helping produce low end.the more rpms the motor makes,the valve opens up,allowing the exhaust to flow out faster,helping with top end power.i know on the cr250 motor i had in my r,it was all controlled by centrifical force of the water pump/crank.it is a cool design,and really brodens the power band,instead of being like a light switch,they pull a little smoother from the bottom rpm range up.

o yeah,red's 250r is super fly.nice ride man!
