yeah its just a flapper like they said above I took my whole pipes off so i am not sure what you need to do but 1 things for sure you dont need it to run your bike.

 

The aussie bikes must have a flapper valve on 1 exhaust pipe, main reason at a guess is to keep the noise at idle down, when i replaced my slipons i just fixed the flapper open with a bit of wire, now it idles like a Harley not a moped

 

Thats what it be alright. You'll probably find its attached to a small butterfly type valve on the pipe below and in front of the passenger footrest.
Disconnecting it will either a) do nuthin if you're changing out the pipes as the valve will go with them, and/or b) set a warning light on on your console in which case you'll need to "trick" the esm into believing all is good and right in the world. You can use the bikewerx trick box for this (its just a plug adapter), or work out the wiring and loop the sensor wires yourself.

 

Disconnecting the cable will leave the valve in the closed position relying on exhaust pressure to push it open , probably not a good thing, valve needs to be tied in the open position

 

The OP said he was getting rid of the stock exhaust - so no valve to stick either way

As has been said, you can take off the cable and the motor from the battery box to tidy things up. But you will need an eliminator plug under the seat where the cable for the motor emerges from the loom or you will get speedo error codes.

 

You can get full control over the valve with this product from Zodiac.


I have a SERT and the valve is always open. You can always disconnect the cable from the valve and strap the valve in open position. You shouldn't get any error codes if you do that.

 

the cable fits to a cylinder on the side of the exhaust pipe. As you roll the throttle open (with engine running) you will see it open and close.

 

Hi,

I ride a 2010 street bob. I have been trying to figure out how to force open the valve at all times since that sounds better. I did few mods such as forward controls, SE exhaust slip ons, SE stage 1 air filter

thanks

 

You need a trick box from Bike werx http://www.bikewerk.com/

Site is in German, but basically you plug it into the esm and it "tricks" the esm into holding open the valve permanently.

I have one on my FXDC, no issues to date.

If you get one let me know and I can send you the English install instructions I made for another rider here who bought one.
