does anybody make one for the pred? or will one for anouther quad work? i emailed scary fast about theirs and the said they dont make one and there isn't one that will work. and it also sounded like they don't plan on making one for the pred either. there must be one out for anouther quad that would work like a yfz or 450r. thanks for any info! thay are supposed to be a good mod for the price. thanks very much for any help.

 

Power valve on a four stroke??[img]i/expressions/face-icon-small-blush.gif[/img]

 

I've seen them on cars so I take it can be done. But you would want to be one hell of a mechanic.

 

In all my thinking I can't imagine why you would need a power valve on a four stroke. A power valve is used to change the exhaust port height on a 2-stroke, last time I checked those four stroke ports were tricky things to work with.[img]i/expressions/face-icon-small-wink.gif[/img]

 

yea those 4-stroke ports are pretty hard to alter [img]i/expressions/face-icon-small-wink.gif[/img] considering they DONT EXIST. lmfao you cant powervalve a 4-stroke.. LMFAO

 

I don't know if you can apply whats in cars to quads , but I know a guy whit a type-r civic V-tech and he says he has got power valves. It came up when I was showin him my zilla jug.

 

What he's talking about is the powerbands, You don't need a powervalve, just go buy a red powerband and you'll see a huge power increase.

 

Thats different alright. Must get back on to him

 

lol, i like the red powerband but the pink one rips man![img]i/expressions/face-icon-small-wink.gif[/img]

 

I got some new powerbands they are blue cant wait to use them with my naaas. LOL
