EXUP Actuator Removal
« on: Feb 17, 2010, 12:29:56 pm »
I have installed a V&H Big Radius and I was wondering if I can just remove the EXUP valve actuator completely or does it need to stay there with no cables installed???
Back into the Motorcycle Life after a 30 year Hiatus...What a bike to get back into it with!!

    If you unplug the servo motor it will generate and error code in the ECU.

    Just leave it there without the cables.

    I am removing this post. I apologize to anyone who tried this and it didn't work. I DID do this on an R1 for a buddy. The guy I got it from apparently reverse engineered a Graves unit and I have not tested it on a Raider. Again, apologies, as I should have stated that disclaimer on the original post.

      I tucked mine behind the frame with a couple of zip ties, and it is completely hidden.

      I don't think anybody has a problem, they just want to lose that servo motor since it serves no purpose.  It's just a thing.

      No, you need not doanything.  If the cables aren't connected, it only keeps the error codes from being generated.  Oh, it still makes noise when you turn on the key and it increases the weight of the bike a little bit.

      no, it doesn't do anything if you've replaced the stock exhaust. Just some guys want to remove it to save weight, clean up the back, or stop the annoying whine noise when it cycles when you turn the key. If you do, there's a way to do it, if not, you can leave it with no problems

      But... yes there is a but. If you DO remove it, you have to do something like I suggested above, otherwise you throw codes and set off the light.

      If you cant fix it with a hammer, you've got an electrical problem.

      Anything is possible, but from reading some posts on other forums I'm afraid ths fix just doesn't work under all circumstances.  It takes a more complex kind of voltage divider to fool this system.

      Thanks for trying it.
