Exhaust Valve Cable Disconnection
« on: November 13, 2018, 10:34:10 AM »
Hi All,

I did a search but didn’t find anything definitive on disconnecting the exhaust valve cables.

My understanding is the cables can be disconnected and left in place without an error code being thrown?

As the valve is after the cat i am assuming it is simply for noise restriction and wouldn’t affect the fuelling at all?

I have just fitted my LeoVince can and whilst i am not ready to go full headers until my warranty runs out I wouldn’t mind a little more noise down low.

Anyone who has done it and has some feedback would be much appreciated.

Hey mate, I have fitted Akra headers. Fitted Servo buddy when I removed cat/ flapper valve assembly to eliminate fault code. No fault code at last service according to service manager. Hope this helps.

The valve is there to help the bike pass emissions testing. Removing the cable won't bring the warning lamp on the cluster... but it will log a code in the ecu that a dealer can see when they scan for codes.
I need to return some videotapes.

Servo buddy will prevent the code from being logged - if that sort of thing worries you

Here are the instructions from Akra but they will apply to you the same.

https://www.akrapovic-auspuff.com/pdf/akrapovic/S-B10SO4-HZDFT_montage_EN.pdf

In the 3 years I've been on here and the other site that has now closed don't think I have ever seen anyone do what you want too do,not to say it can't be done but what the end result will be who knows?

As you will see you take the motor out that operates the flap disconnect the cables and fit back in after you have sealed the box up that it is in so you keep the crap out.

I never bothered with the servo buddy it shows nothing on the bike unless you plug the diagnostics in but it has no effect on how the bike runs.

Thanks for the replies.

That confirms what I thought. I won’t bother with the servo buddy, I am not worried about fault codes in the ECU as long as it doesn’t show on the dash.

Just to clarify i am only disconnecting the cables at the valve not removing the cables or servo motor.

Thanks for the assistance.

Just to complicate the issue the guy who owns this(he's well connected) wired a flapper valve into his Akra system

You can just disconnect them but they will flap around if you don't secure them. It's a 10 minute job to remove the servo, take the cables out and reinstall it.

Thanks for the responses and info.

Looking at the Akra instructions for the headers I can see it will be easier to just remove the cables from the servo altogether.

Guess what i will be doing tonight!

Thanks again.

I did exactly the same thing...the Arrow header instructions show how also.
