Servo Cable Removal || 2016 BMW S1000RR

while I continue shopping for an aftermarket exhaust, I decided to improve the stock one. Took the baffles out of the can, and removed the servo cables.
Trying to upload more vides to my channel, so thought I would share.

That’s the quietest s1000rr engine I’ve ever heard 👍

A puddy knife and a rusty ass crescent wrench, nice.

[@Synthad1]

lowdime305 thanks! lol The tool collection is a wip.

[@Chris-Brauch]

Thanks for the video. Just did my S1kr and enjoy the deeper sound 👍🏼

[@The3Halls]

did u get no warning message

@@The3HallsI got dash light on , on my XR

Is that brown paint on the wrench

[@nikolan6366]

Nothing shows on the dash like 02 ,becouse the servo cables been off?

[@Synthad1]

You need the “servo buddy” so there’s no errors. Simple install

[@myF430Spider]

You seem to have a cat delete there, how come the servo wasn't removed?

[@Synthad1]

Matt Kazan no cat delete. You might be thinking of the ‘17 or newer. This is the 2016, which was the year before they started the big euro cat. So mine is smaller and tucked under.

@@Synthad1 Oh gotcha

[@DarkenFool]

no codes?

[@SickPrid3]

it will show error only if there is no signal or wrong signal from servo motor to the ECU. In this situation ECU thinks everything is OK, you can see the lines moving when he twists the throttle

[@sambyf2445]

My understanding is that if you amend / improve / change anything on the exhaust - you will need a remap to balance that change out on the other side of the equation. I removed the baffle on my S1000rr (2015) and whilst the sound is lovely (pops and bangs) the initial low down torque (the immediate pull) is now missing. I am going to put the baffle back in now after having ridden around for a few weeks without it, because I miss the torque. The servo is there for a reason - saying that all aftermarket exhausts eliminate it is fine, but you should also inform viewers that aftermarket exhausts are also ALWAYS accompanied by a full remap to balance the fuel / air ratios!

[@Synthad1]

use the servo buddy

[@jmac22a]

what a shame nice bike set up by the very best engineers then someone comes along and takes the cable out you might be in trouble if anything goes on the engine the showroom you purchased it from or well in there rights to stop all guarantees

[@Synthad1]

James McInerney huh? The servo cable is not something BMW wants. It’s a trick method to low noise emissions.. think... Regarding your concerns about my warranty .. thx.

[@stlmoto5129]

I've had this done at the dealership on my R1200R. It doesn't void any warranties and you can undo it if you like.

[@stevebrown5957]

The butcher

[@paulnwt]

The valve is used to control reflections from compression pulses back to the exhaust ports to improve gas flow, not to reduce noise. You've just ruined the power output of your motor and who knows what else damage will occur over time.

[@Synthad1]

Paul Newton wrong.. every single S1kRR (or any bike with servo) that has an after market full exhaust, rids the bike of the servo system. after market exhausts don’t come with a replacement servo. So saying removing the cable ruins the power and everything else is wrong, or would apply to anyone that has an after market exhaust (99%) Talked with BMW tech as well, and many articles on this are on offer.

[@Synthad1]

I’ll add you are correct in theory, as far as what servo’s do. But in this case, the damage you claim will happen is incorrect

[@paulnwt]

Synthad1 i stand corrected thanks. So what does it do, why include it, and why does my HP4 not need it removing?

[@TheDonmackinnon]

Yes I’ve seen that information thanks, it’s going to be a conversation that has two answers I’m afraid. Older bikes did use then for exhaust advantages but Synthad1 is correct, they are disconnected when upgrading the muffler or full system with no place to refit on new exhaust. Certainly sounds better without it a low revs/ idle. They are also used to reduce noise at low rpm so bikes can meet Euro5 noise standards
