View Full Version : Looking for used Exhaust Actuator Unit and Uly Windshield

04-27-2009, 02:44 AM
Hello Fellow Buellites,

I'm interested in purchasing the oem exhaust valve actuator to replace the existing (broken) unit on my xb12xt. (This part mounts to the top of the air box on late model xb's, and controls the valve position on the stock 'interactive' muffler). The specific part number is s1138.1aa... The part is obsolete for all those running aftermarket (modified) exhausts, so I'm hoping that there will be a few lying around.

Also, I'm interested in the stock windshield on the xb12x uly, not the taller version found on the xb12xt.

I appreciate any feedback guys, thanks!

Thanks for checking Fock!

Edipis... the part number should be located on the bar-code sticker. I've sent you an e-mail as well. Thanks!

If you need one still let me know I have one available from an 07' XB12R.

Hey Buell_Cru,

Any part numbers on yours?

The stock part off my '08 xb12xt reads S0138.2AAA... However, I've been informed by my local Buell Dealer that the above part is discountinued. If I want to order a replacement direct from Buell they'd be shipping me S1138.1AA, which is the updated replacement. So, an actuator matching either of these models is ideally what I'm looking for.

Thanks for any info!
