Are the Exhaust Valve Actuators compatible from 2004 to 2008 model years? (SO138.1AAA vs. SO138.2AAA)

I don't know the years, other than that my original was on my 2007. I got another and made an adapter bracket:

All of them compatible, but until 2009 or so they had plastic gears which inevitably fail. The latest version had metal gears and are much more durable.

The actuator itself is the same as one used on some late model Mustangs. The Buell factory part was ~$150; a Dorman version of the Mustang part is $50. You do have to cut the cable quadrant off of the OEM part and TIG weld it to the shaft on the Mustang part. This text and photos were borrowed from the BuellXB forum:


quote:

here is pic of your stock IEV actuator motor assembly. new available but pricey at around $149 list. notice bell-crank assembly. first series of letters/numbers on barcode sticker is the buell OEM part number.

here is pic of DORMAN substitute unit courtesy of FORD motor company. retail for around $60 and readily available. DORMAN part number is 911-912. notice the bell-crank assembly.

easy to transfer the XB bell-crank to the Dorman. Dorman is superb quality and plugs right in.
Dorman internal gears robust and all metal. Superb! your OEM cable bracket easily transfers to the Dorman.

thank me later.

That seemed familiar. Turns out, it must have been mentioned on BadWeb, because I had saved this link: https://www.buellxb.com/forum/showthread.php?52942 -Disabled-exhaust-valve-actuator&p=587824&viewfull =1#post587824

Furbaby,

Per another thread here the actuator is either on or off. As a basic switch I'd be comfortable trying whatever part was available on my bike... looks like the newest pn is S1138.1AA

I have a working S0138.2AA, if that's the part you're looking for, lmk.
