i powervalve is a valve that is in your exaust port that is closed to raise yur compression. when it opens at a certain rpm, than you have a quicker reving quad. the powerband is when your quad makes power. so, if you quad makes power from 3000 to 5000 rpm than that is your powerband. that is where your quad makes power

 

and i never said a banshee had a power valve but i know that they have a power band or w/e u would like to refer it to

 

ok did i not try to tell u that when i said the power valuve was a setting when it hits that rpm that flap open witch causes that sudden burst of speed / POWER BAND

 

so since we solved that problem what else is there to fight about ,,,,,,,,,,,,,still didn't get an answer on 400ex and push rods? just wondering

try to speek engish. i cant understand what you mean.

 

a 400 ex does not have pushrods. i know this because it has an overhead cam. what this does does is eliminate the need for pushrods because it puts the cam right where the valves go.

 

Wheres the video of a guy with a 1000cc decked out raptor racing a banshee 350 with pipes and a filter and the banshee still whips his *** by 2-3 quad lengths.

 

please give me a site telling me this u saying it does not mean ne thing

 

i think u might have to learn to read first b/c its in perfect english
