IAC Removal
« on: Oct 08, 2009, 11:54:32 pm »
Ok guys,

I am going to try and remove the IAC module on my bike and use the "manual" adjustment on the throttle bodies.  "We" (my technicians) think we can remove it and make it work better without that stupid thing!  Should quiet down the "sucking" sound at idle when running a big air kit.  It should also stop the floating idle upon start up.  On the Warrior, we can just un-plug without throwing a CE light, but not on the raider.  We are gonna leave it plugged in and plug the vaccum lines coming off the throttle bodies.  Once the vaccum lines are gone, I should be able to adjust my idle.  I will let you all know the results next week and post some pics.

      I got everything removed last night and what a difference!  No more loud sucking noise from the IAC and I can control my idle!!!  Here are a few pics.

      Here is what is removed Idle Air Control Valve in the neck of the bike


      Here is where you plug the vaccum lines coming off of the throttle bodies.  I used 1/4" vaccum line plugs that you can get at any auto parts store


      Here is where you adjust the idle manually - Working on adapting a Warrior idle adjust screw.  More info to come!

      Here is the neck cleaned up where the old vaccum lines were and now it looks clean!

      Sounds interesting, will it produce more power?

      It should also stop the floating idle upon start up.  On the Warrior, we can just un-plug without throwing a CE light, but not on the raider.
      I was actually messing around with this a week ago ... didn't come to any preferred solution, but it appears that as long as the electronics are functional, it could work. Will continue to check out the thread.

      FWIW ... my Cold air kit cost me a total of about 65 bucks and some zip ties...

      K&N RU-2580 Filters work fine, although I am working on something completely different, should be operational by January.

      Update,

      We used the Grizzly 660 idle adjustment extension so that we can adjust the idle without taking the tank off!  The part is #40 on the diagram and the part number is 5km-14103-00-00.  Looks the same that is on the Roadstar and Warriors.

      ntx,

      Did you remove your IAC valve?  You can unplug it sensor and all and it will not throw a check engine light.

      I ran it that way while I had the tank off last week, using the throttle position for idle. I didn't want to stick with it that way because of my 150 mile a day commute. Wasn't sure if it would end up "loading up" on me over time. Now that it's road tested, I will re-remove the IAC and clean her up some more. At the same time I will activate my new Accell Super Coils ... need different plugs. I already have them mounted under the tank in a steel tray I fabricated. I will post pics when done.
