D I Y stacks Noise?

JoeH · Aug 23, 2003

Hey all,
I just installed the do it yourself stacks today.
My question is , is the "chirping" or "sqealing" noise everytime I crack the throttle normal? Is this just the sound of air sucking in or what?
I'm not sure if I did somthing wrong here.
I'd appreciate any info or guesses or what ever.
Thanks,
Joe

No, I don't think it's that. This is a new noise. I wonder if it's the speeded up air whistling across the throttle plate? I'm not sure if I'm gonna be able to stand it. [V]

Sync the throttle bodies and those little birds may go away. If those stacks are really filters, turn them to another position sometimes helps. Chirp'in can be gotten rid of with some persistence...

Yea...I did the sync. after the install. Synced them at 2500 rpms.
These are the stacks like Churchkey did, with the mandrel bent tubing and the K&N filters. I just rode for about an hour, and another noise that sounds like I have the exhaust pipe mounted to the under side of the gas tank shows up around 2000 rpm.
BTW, does anyone know how long the straight factory stacks are? I'm thinking about making some straight ones about 3 inches long.
Thanks for any input.

I did the same mod following Churchkey's instructions. And yes its makes a high picthed chirping noise. Mine makes it around 2000/2300 RPM range. Can't tell why, kinda got use to it.

you can hear that??? with aftermarket pipes (bubs) i cant hear anything from the engine breathing?

Sometimes have the same chirps with the Stage IV velocity stacks. Did the tb sync at 900 rpm. The go off sync up to 2000 rpm and are in sync again thereafter.
I figured it is the air being sucked in at higher velocities.

I need to listen closer I think. I swear I haven't heard this noise

If you got the birds, you'll know it - loud!

I had the chirps for about a month now. Was troubleshooting my 2.5K - 3K rpm intermittent problem and removed and changed the air filter angle. Chirps are no gone. Thanks for the tip, PURSUVANT!
