Default +3HP & +10TQ with this simple mod? Anyone with experience on this?

Hey guys,

I've read online that under the tank, where the airbox is located, there is a small piece of plastic that can be easliy removed to open the air box by a small amount. According to the article, it is just a piece thats put in there to silence the intake noise.

To perform the mod you must remove the two rear tank bolts and slide the tank back a few inches. You will be able to see the piece in question and can remove it by simply pulling it out. You then just bolt the tank back on. APPARENTLY the people who have done this have gained an extra 3HP and 10TQ at the wheel when put on a dyno. The only draw back is that it allows more noise from the air box to be heard much louder (which may not be a bad thing to cover up the sewing machine purr of the bike).

Has anyone else heard of this or done the mod?

Not only have I heard of it, but I am the one that ran back to back dyno's on 3 different X bikes to confirm it. of the three I saw 3-5HP, and 7-10FtLb. The proof is in doing it, and then you will have no doubts

I'm not an asshole...I just type that way

Well then...I guess I have a little DIY project to attend to! Did you find the bike was much louder than stock? If so, was it too loud for comfortable long haul riding?

I searched for a few different things and none of the searches came up with anything regarding this mod. Could you please point me to the thread? Thanks!

Here's one you might want to check out Snowman. It's a combined effort of several people with our resident expert, KevinX, answering key questions to make all of it possible. I affectionately call it the "poor man's stage 1".

Intake noise is only noticeable at low speeds to me

I followed it and yes there is definitely a difference! Makes the bike actually feel more like a beast and you can actually hear the motor now.

Blest with victory and peace, may the heav'n rescued land
Praise the Power that hath made and preserved us a nation.
Then conquer we must, when our cause it is just,
And this be our motto: "In God is our trust."
And the star-spangled banner in triumph shall wave
O'er the land of the free and the home of the brave!
