How To Remove The Servo Motor and Install Servo Buddy on 2016 BMW S1000RR

[@yamayari8351]

Thank you! I was here for like 30 minutes looking for a hidden screw lol 😂 super easy with your help. Thank you from Debary Florida! YamaYari 🙏

haha, good stuff

Im busy with it cant get it.of what is that litle hook thingy at the bottom

[@bobjohnson2920]

The valve was actually designed to create more torque in the low to mid range, then eventually become fully open in the higher RPM range. At the same time reducing the noise decibels. You will lose some low end power with the stock exhaust, but gain this back by going to a full aftermarket system and a tune of course. Not sure about the pre 2015 models, but similar design 2015-2022. In 2020 they have more ECU, exhaust, intake restrictions. Brentune has all the stuff to you need to eliminate/delete the restrictions.

[@TheBikeStig]

appreciate the comments mate, interesting how this all works.

@@TheBikeStig Actually it was only installed for Euro 5 noise compliance. Same as the intake flapper. Compliant bikes have to meet a set db at a set rpm, a ride by noise limit of 77dbA at 50kmh. The bike is 100% closed loop with wide band O2 sensors. It will tune itself to meet it's programmed mapping ie adapt to changes in the intake and exhaust. This is exactly why Bren prefers to tune BMW bikes. He only has to set the tables to what he wants and the bike adjusts the fueling/timing to meet those map parameters.

@@MrMike-fn4hi cheers for the info mate, the direction of the electronics in bikes these days blows my mind. I think ill just focus on riding em 🙂

[@electrobitnewportapplerepa7219]

@@MrMike-fn4hi so there will be no low-end power loss i guess? Thnaks

[@TheDervMan]

FYI you’ve got the operation around the wrong way. The valve is ‘closed’ on idle to reduce noise. Once RPM’s are over 1,500 ish the valve opens. 👍🏻

[@TheBikeStig]

I listened to it after it was uploaded and realised it could come across the wrong way. I was of the understanding, certainly for this BMW, that at idle it is open and then as you start to open the throttle it closes to reduce noise at low rpm (i.e. the noise testing range) and then opens after that. Thanks for the comment, I better go and check with the BMW folks.

[@TheDervMan]

@@TheBikeStig On the GS it's closed when on idle. Someone very kindly videoed it in action on the GS :-) kzbin.info/www/bejne/jYCQoYOBr9qShKs

[@TheBikeStig]

@@TheDervMan thanks for sharing that, very informative. I wish I had done that on the S1000RR now.

[@ZrTubz]

What about the other valve in the headers?

[@TheBikeStig]

Depends on the model I believe. Later bikes have more than one valve but not this year model.

[@martinmoran89]

I removed my header servo motor on my 2012 RR and installed the servo buddy

[@d3klin]

Is it necessary to remove servo without change whole exhaus system? I have just changed slip on exhaus no decat. Also is it not using servo for any other purposes just for get bike quiet?

[@TheBikeStig]

best thing is to talk to your local tuning people about this, soon as you start changing things you should be doing a proper tune of the ECU. Regarding purpose, I am not an expert but I believe the servo not only affects noise at idle, it also has a positive effect on low down torque ... like I said I am not the expert on this.

[@marko_s1000r]

Where would you plug the second servo buddy if you have done a full exhaust?

[@TheBikeStig]

I don't actually know how that works mate, my personal bike is a 2016 model. I ride a 2022 BMW for the Superbike school but we run stock exhausts. I'll have to ask someone, Im at the track this week so should be able to find out soon.

[@TheBikeStig]

P.S. The early version (pre 2020 I think) only have one servo motor.

[@martinmoran89]

I run 2 servo buddies on my 2012 RR. One for the rear valve as per this video and one for the header servo motor.

[@th3s41nt]

If I have the scan tool to delete codes do I need the servo buddy? I bought my bike with the cables zip tied to the frame and it’s ugly. I didn’t know it was that easy to just get rid of the complete tumor

[@TheBikeStig]

I am not the guy to ask that as I don't know. But I would think you would get a constant fault code that keeps coming back and who knows what that affects in addition to a warning on the dash. I'd be putting in the Servo Buddy.

[@th3s41nt]

@@TheBikeStig awesome thank you for your reply. I’ll be patient and just wait for the buddy to come in

[@TheBikeStig]

@@th3s41nt Makes sense mate. Imagine that annoying fault code on the dash, the service reminder is bad enough 🙂

[@garyoconnor5332]

So i have disconnected the cables on mine and have no issue for months. Then i started getting power loss basically cruisng along no power but still have electrics working then back again. Only fault code is for this but 99% sure always had that fault and thinking its another issue

[@TheBikeStig]

Im not the expert on that mate, I'd be talking to someone who can get all of the information from you about what is left in place. If you put a servo buddy on it, I do wonder if it might have a problem. Wish I could help more mate.

[@anislicina3065]

Will this work on a 2022 s1000rr?

[@TheBikeStig]

I want to answer but I'd be asking someone who's done the work on a 2022 model. I have a feeling there are multiple servos ... might check that one out.

[@jaybee-xo9nh]

Can you not just remove the cables ?

[@TheBikeStig]

yep you can. The internals would remain and stay open. Depends what your goals are mate.

[@TS-2SLoW]

Should atleast actually show how to pull that shit out. That’s the hardest part

[@TheBikeStig]

hard to film too lol

[@TS-2SLoW]

@@TheBikeStig I was irritated when I commented that. My apologies. It took me 2 hrs to get it out. But your video was very helpful. I watched other videos and they were tearing all kinds of stuff off. Thank you!

[@TheBikeStig]

@@TS-2SLoW hey no worries mate, all good

[@mavnl81]

​@@TS-2SLoWim still bussy with it everything loose cant get the sucker out. What is that litle hook thing.on the bottom of the servo

[@parkinkevin]

Why not just disconnected the vires? So unnecessary 😒

[@TheBikeStig]

That's a fair question, if I'm not using it I'd rather remove it rather than have it sitting there with cables tied out of the way.

[@512460]

What's vires? Is there an easier option?

[@parkinkevin]

@@512460 The easiest way is definitely just to disconnect the wires from the valve

[@512460]

@@parkinkevin oh nice simple. Then this will keep valve in open position? Thank you. This option sounds great rather than forking out for a full system or a shorty. Considering bmw gave it an akro stock.

[@parkinkevin]

@@512460 yes. Then it will stay open. And it takes the strain off the little servo motor that is prone to failure. So it's a win win
