An alternative is to place a marble in the rubber tube coming off the right side of the air box. It will stop the air flow to the pair valve and the only thing you need to remove is the right side air intake duct cover. I found the marble trick on a hayabusa forum of all places.

My bike backfired a lot with my cut down pipe, when letting off the throttle at high rpms. It was annoying and embarrassing.

To answer the question a few posts ago, I paid right at $36 or $38 bucs for the Drivens shipped to my door. As far as weight, maybe 1.5 lbs. Not much, but it's really not needed on the bike and takes up space. The plugs are much easier to access now as well.

I did my PAIR removal about a year ago, but I think I removed the reeds. What is the reason for keeping them? I know my bike runs pretty darn good without them.

there is no reason. it's just a lot easier if you get block off plates that allow you to keep them so that you don't have to drill through the screws on the reeds.

i had to drill through the reeds on mine

If I just do the same thing as the moosestang did.
Place a marble in the rubber tube coming off the right side of the air box, but what about those two wires ?
Is there any mather leaving those wires connected or do I have to take it off ?

i took mine and just linked the hose together. pulled the unit, as pictured. left the oem covers in place and just ran a hose to them.capped all the airbox holes. the crankcase vent to the air box i cut just short of the throttle cable mount. and put a "pcv valve" from the auto parts store on the hose. now the crankcase doesnt vent to the airbox . i want to say i felt a difference, but i have no dyno sheet to prove it

i know this thread is dead. but the guy said that the driven blocks have a spot milled in the blocks for the screw in the reeds. yet and still everyone keeps saying drill them out. am i missing something because he didnt have to remove them.
