Disabling the exhaust flapper without a cell.

I have read the Faq but I'm still unsure about how to do this. All I wan't to do is disable the flapper valve in the exhaust. I have a stock ecu and I don't really care about removing the servo and cable for weight reduction. I know I can't disconnect the electrical connection without throwing a cell. Is it possible to leave the servo motor plugged in and just disconnect the cable at one end without throwing a cell? If so which end of the cable is better to disconnect? At the servo motor or on the exhaust? I'm trying to do this the cheapest way possible. I know I can do this by installing a Duc.ee but is it needed if I leave the servo motor in and connected and just disconnect the cable? Does the SFS do the same servo check/sweep as the 1098 when you turn the key on? From reading I already know you can't just disconnect the cable on the 1098 without a cell. You need a stopper plate on servo to prevent a cell. I appreciate any information about this or links.

Hi. Are you doing this to smooth out your lower rpm a little, and/or make the bike a little louder at low rpm? Is there another benefit I don't know about?

From what I understand if you remove the cables from the motor it still scans for stops but a small plate that Chris at desmoworld in germany sells to fit on the motor takes the place and fools the ECU.

Both of those reasons. My bike is pretty smooth on the bottom end with the minimal fuel correction I have done. I'm pretty lucky. I'm still using the 02 sensors but have the AFR richened from stock. I wan't to eliminate the bike making additional unneeded fuel correction around the exhaust flap. I'm hoping that by disabling the flap I might gain an even smoother bottom end. My SFS already sounds good with the slip ons I have but if the sound increases a bit that's fine to.

I found the plate you where talking about. So the SF is like the 1098/1198 as far as the servo doing a check for the cable at startup. Have you ordered from Desmoworld before? All the prices are in Euros and in German language and I don't see a conversion to USD. I think I'm going to just go with the Duc.ee to get the job done. I know I won't have a problem getting one from Vizible Technologies. Then if I ever decide to take the servo out I can. Here's that plate from Desmoworld just in case someone else is interested.

Thanks. Maybe I'll try that. I won't really know until the spring if it works when I can ride again.

As said, you can remove the cable from the servo and not get a light. You do need to leave the power connected to the servo.

Duc.ee is the way to go or just turn the servo off in your ECU with a tune.

Do you recommend disconnecting the cable at the servo or down on the exhaust at the flapper to not have a cell come on? Or does it even matter which end of the cable is disconnected as long as you leave the power connector plugged in?
