Exhaust Valve Actuator

[RedDead]

as i was in the process of doing the breather mod...i realized that my exhaust valve actuator cable looked a lil funny...i turned the bike on and revv'd the throttle up....i realized that the actuator only works when it wants to ....is this because of all the play in the cable or does this cable look ok....also i found this hose that looks like its suppose to be hooked up to something but not really sure..any body wanna put in their two cents?http://www.buellxb.com/buell_images/14415_20120921174837_L.jpghttp://www.buellxb.com/buell_images/14415_20120921174749_L.jpg

The exhaust actuator is supposed to "operate" in the mid rpm range.

Where's the hose originate? We need to know at least one end of it...

[beatsthejaps]

Cant tell much from the picture but are you sure thats not your breather hose? Just goes in the bottom of your air box if so

[okey]

Cable should be taught not loose like that. Actuator only operates at half to full throttle via ecm control. I have pulled my cable open fully and put some vac hose to keep it from closing giving me an open exhaust from idle.no problems at all

[Sirius815]

Cable may be loose from the actuator at the exhaust then.

and from what i can tell that hose is the trans breather

[RedDead]

the hose is the trans breather i'm guessing and the actuator is actually not connected because my jardine pipe eliminates it....sorry newbie mistake....my gsxr had the exhaust valve before the muffler and not in it..thanks again buellxb

Hi
I had a diagnostic done on my 07 firebolt and was told my exhaust actuator valve had gone i tried to buy one here in south africa where i live but no dealer here can help me does anyone know where i can get one

Most people just remove them, it doesn't hurt anything to remove them. If you really want one I'm sure someone could sell you a used one as just about everyone takes them off their bike.

Welkom Deon, waar bly jy?

I recently took mine off and wired valve open (my cable was going) and with the help of lawdog on here I managed to reprogram ECM.

Simple and now I have solid power through all the revs!

I am in Cape Town by the way.

Ek bly in knysna maar sukkel met die harley ouens om een op te spoor waar bly jy ?

[Deonkotze]

Sorry i see you are in capetown,how did you get your warning light to go off after you removed yours ?

[lawdog]

You program the ECM to turn off the valve and error checking for the valve.

Deon, send a message to Lawdog and I am sure he will be willing to talk you through it. You need to have a diagnostic cable, a laptop and level head, but it is pretty easy!

[Deonkotze]

Ok Great thanks for the tip will try him cheers

[lawdog]

If you want to remove the exhaust valve and hardware get an ECM cable and I can show you how to turn off the valve.

Hi Wally I ordered a new actuator from st.paul Harley in USA took me 5 min been waiting for the harley dealer for 2 weeks and no luck,after i install the new one will the check light go off automatically or do i have to program it again?
Thanks

[wally]

It should, I guess, as it will be functioning properly.

I just took mine off (my cable was nearly toast), wired the valve open, removed actuator and reprogrammed the codes.

Now the bike has grunt and pull through whole rev range. Used to battle ate low range revs, but there is a definite change now!
