Aprilia RSV4 RR/RF Exhaust Valve Cable Removal (2016, 2017, 2018)

In this video, I show what is needed to be done for installing an aftermarket exhaust on an Aprilia RSV4. Removing the stock muffler will result in the need to disconnect the Exhaust Valve cables from the flapper valve and the service motor behind the right side forward fairing.

[@one-of-us9939]

Way sweet. Thanks for showing this. An often forgotten responsibility of can evolution.

[@SkyhookStudios]

Yup and many more manufacturers are going this way. My new Africa Twin also has a built in butterfly valve that will need attention once a new exhaust is fitted.

[@apriliarider6072]

This is spot on! Only thing I did differently when I did mine was actually remove the cables. Great work sir!.

[@SkyhookStudios]

Thank you. I was going to remove my cables also, but was advised to leave them due to warranty concerns. If your out of warranty then I'd say take em out.

[@qgiftedhands]

Is it easy to remove the cables? And did you guys secure the valves in the open position?

[@Budget-Cars-And-Bikes]

@@qgiftedhands I believe the valve is in the open without the cables, the cables actually CLOSE the valve, so when not connected, the valve is always open

[@awesomebase]

Awesome video, thanks man! I've got a Tuono vr RR and looking how to do this properly... I know it may not be exactly the same, but removing the cable heads from the servo motor is what I was trying to find out how to do before removing the stock exhaust...

[@motosagela]

Great explanation. I have a new competition werkes exhaust I'm installing. Thank you!

Very nice!!👍🏿

I’m giving it a go now on my 2017 RSV4rr. 😬

[@DylanGSXR]

Great Job , you can buy a servo eliminator and take the motor off too ( weight saving 😁 ) or if it's flashed it gets turned off so no code's . cheers for video going to do this myself at weekend just picked up 2020 tuono a few days ago so getting it prepped for a new end can.

[@SkyhookStudios]

Cool, when I posted this there was no option for an eliminator.

[@DylanGSXR]

@@SkyhookStudios yes sorry after i wrote it I realized it was a few years ago 😯. Cheers .

[@djnikimatteomatteo9291]

Thanks!!

[@Mgixxer-vi7gr]

I dig it! Thanks for the tutorial! Curious, do you know the differences between the exhausts SC Project offers for that bike? In other words, are their exhausts merely different cosmetically? Thanks again!

[@SkyhookStudios]

I'll start this reply by saying that I have not heard any aftermarket exhaust, for the Rsv4, in person except for the GP-70r. I would recommend checking out numerous videos to gain a better idea of what they sound like. Personally I would bet that the SC 70r and CRT sound very similar to what the Austin racing would sound like. The Akra and SC large cans probably sound simalar to each other too.

[@padi917]

Hello,the last year I bought a rsv4 identical to the video and a sc project and I did exactly that and the bike went into breakdown mode and with a protection map to get to the workshop and alert message, and try to leave the servo connected which is broken if you leave it connected. Solution: you can buy the aprilia akrapovic with which you are given a code to change to an akrapovic map where that valve is eliminated (you only get that code ONLY IF YOU BUY THE AKRAPOVIC APRILIA) and the Another option is to put a racing ECU from aprilia where the loaded map already comes. And last and most recent option is to put a healtech exhaust valve emulator but I recommend the akrapovic map because when removing the catalytic converter the motorcycle is very dry and that can break the engine. Thank you and sorry for my english, thank you

[@eseparanoiac]

hablas español? estoy en la misma situación y creo que voy a comprar el akrapovic de aprilia tan solo por el mapa. Cuando le cargan el mapa race a la ecu por comprar el akrapovic, puedes desconectar la valvula de escape sin tener ningun tipo de problema o hay que hacer algun apaño? Gracias

[@padi917]

@@eseparanoiac Hola soy español de canarias jeje y si se puede quitar la valvula de escape sin problema una vez cargado el mapa en la ECU,tambien te anula lo de los gases de la culata y lo de la recicladora de gases del deposito que es la botella que esta a la derecha

[@padi917]

tambien te digo que ya la embresa Healtech ha sacado el inhibidor del dervo de la valvula de escape que hace que no te cante la averia y vale como 50 euros pero mi recomendacion es que si pones el escape pongas el maping porque la moto se queda muy fina al quitar el catalizador y es como le sacas los tres caballos que te da la cola de escape.Saludos y espero haberte ayudado

[@ferranperis5639]

El mapa akrapovic con que tubo te lo dan? Por que me regalaron por promocion el akrapovic de titanio pero de mapas nada.. los mapas son para el akrapovic de carbono entiendo no?

[@padi917]

@@ferranperis5639 te lo dan con el de carbono porque ese de titanio es tipo original con catalizador y valvula de escape ,el que tienes que poner es la cola de carbono que viene con el mapping y sin catalizador ni valvula de escape

[@affirmativehouston]

Thanks for explaining that. Maybe i missed it but, what did you do with the flapper valve after removing the cables? I understand it is spring loaded closed. So did you wire it to stay open? Or, did you remove the valve?

[@SkyhookStudios]

I assume your referencing the valve in the exhaust. If so, the only reason why you would be doing this mod is if you removed the stock exhaust all together. I swapped the stock pipe out with the SC Project slip on and it does not have the flapper valve.

[@affirmativehouston]

Ok I now understand the flapper is in the pipe that is removed. Older models have the flapper in the header at the slip joint and it stays. Then must be wired open. I didn’t realize your year and model when I commented. Cheers

[@kengray1708]

I am in California and am having trouble buying after market exhaust muffler, so for now I’m staying with the stock can. I don’t understand the purpose of the flapper valve. Why would it ever be in the closed position? I want to remove the cables and assume the bike will run better without the flapper valve closed. Will the ECU need to be updated? Well done video. Thanks

[@ryanlowe2808]

The purpose of the valve being closed is to limit dB (noise) at lower RPM and mainly to reduce emissions (Euro 4 on this year). It opens as you increase throttle. Once you remove the valve, even with the stock exhaust pipe, it’s going to be much louder and aggressive (lean). Same goes with aftermarket exhaust. You’ll be okay running the bike a month or two without getting the ECU flashed or buying a new race ECU, but don’t leave it too long without addressing the ECU. Valve adjustment issues will come up eventually if it runs too lean too long.

[@primedirective00]

If you do this with the stock exhaust on it helps the bike run a LOT cooler but you need to safety wire the flapper valve open

[@SkyhookStudios]

Removing the evap canister on the left side of the bike helps the radiator breath better too. 👍

[@2wheelslunacy]

Hey man, thanks for the video, so just by removing the cables of the servo motor it does not give you a Check engine light or any other errors? is that correct? I was planning to buy a ESE, which is a Servo eliminator sold in EBAY but after watching you video I believe it is not needed if the motor is left connected, am I correct?

[@SkyhookStudios]

That's correct. If the motor is still plugged in you're good. For what's it's worth, 2 things. 1- looking back, I would consider doing the ESE and still think about it time to time. My 2017 gets rather hot and the airflow out of the fairings is minimal at best. The EVAP can on the left and the servo motor and bracket on the right, block alot of air flow through the radiator and out the fairings. I did the EVAP can removal mod on the left side and it has improved cooling on hot days, enough that I don't "need" to do the ESE and remove the servo in it's entirety. Although it does still get hot and I should just do it. 2- Not sure what year your bike is but I know this video is good for up to at least the 2019 bikes. Aprilia did a major revision in 2020 and it might be different. I would check part numbers and or the fourms for confirmation. EDITED- grammer

[@2wheelslunacy]

@@SkyhookStudios thanks for replying, mine is 2018 so they are pretty much the same bike. I didnt know about the EVAP can, do you have a video for that ?

[@SkyhookStudios]

Really late on this reply but check the Aprilia fourms. Someone has a very good write up including pictures.

[@m1ellison38]

So weirdest thing. I put on an Austin Racing similar to that SC a while back and my bike did not have those servo cables. It was the stock exhaust as well. My bike is the 2016 RSV4 RR. Makes me wonder if I'm losing my mind, but I checked the box where I put, my stock pipe and no cables. Do different state emission laws have a bearing on this? Or perhaps guy before me that owned the bike may have had exhaust work done and put the stock pipe back on before selling it. Only had like 2500 miles on it.

[@SkyhookStudios]

Tail pipe emissions, be it noise or pollution, are federally mandated and states don't control them individually. Did the stock pipe have the flapper valve in it? I've seen guys completely remove the cables and that might be the case.

[@djnikimatteomatteo9291]

Question do you plug in everything or just the one with white tab..thanks

[@SkyhookStudios]

Nothing stays disconnected electrically. So anything unplugged, gets plugged back in.

[@andreaprocino7713]

Hello, I am writing because I would like an opinion on the problem I have on my bike I have a 2019 Aprilia RSV4 1100 Factory Yesterday I disassembled the exhaust valve cables (original akrapovic) I did about 10km! I wanted to reassemble the cables in their original position but the valve motor no longer works, it no longer resets the position and a warning light (engine problem) came out on the screen, certainly and because of the exhaust valve motor! My question is can you get everything back to normal? With an error reset? Many thanks in advance

[@SkyhookStudios]

The bike will need to be taken to a shop that has scanner capability. The motor need to be set to a specific position before installing the cables. If you're up for it, find a service manual and give it a go.

[@07giuly]

Great video. Is the same for the 19’ 1100 with akrapovic original exhaust??

[@SkyhookStudios]

Thanks, I'm not sure. Haven't got my hands on one yet.

[@ryanlowe2808]

That system isn’t running the flapper valve, so no, it’s much easier actually! You just have the catalytic converter to contend with, which is easy to remove.

[@dalecunningham622]

Great video, thanks. You haven't had any error codes come up as of yet?

[@SkyhookStudios]

None. There's nothing to double check the servo so the computer assumes everything is ok. It still cycles back and forth though.

[@M-POWER777]

Do you know if the 2015 RF also has this butterfly valve and cables?

[@SkyhookStudios]

Yes.

[@M4rkmcc21]

Does the stock muffler with the cat in it have the servo spring loaded open? Or is it spring loaded shut? I'm assuming open.

[@SkyhookStudios]

Shut.

[@M4rkmcc21]

@@SkyhookStudios just checked there. Its spring loaded open. I need to force against the spring to shut the flap. Probs so if the cables failed the flap would remain open which is safer than the flap keeping shut

[@SkyhookStudios]

My apologies, you are correct. Are you looking to just run the stock exhaust without the cables?

[@M4rkmcc21]

@@SkyhookStudios yes. I done some reading and app it's ok to have the stock set up with akra map and cables removed.

[@tuyenhoang5546]

Can i just leave the cables out hanging? Will it show any error?

[@SkyhookStudios]

If you leave the cables connected to the servo, they will bind up and then the bike will throw a code.

[@tobybarrow4848]

Did you remap it or fit a race ecu?

[@SkyhookStudios]

Yes, Corsa ECU was installed.

[@MrRc57]

I took my cables off my 16 rf Still stock exhaust, My service light has been coming on Should I put cables back on

[@SkyhookStudios]

What was the reason for taking them off the stock exhaust? Besides that, if you didn't take them off the servo end then your going to set the light regardless.

[@philippschaad4426]

but there comes no error light if i put the stock exhaust off and took a sc project on with removed servo cables ? i have a 2017 rr and i dont like the looks of the stock exhaust.. i want an sc project crt but i want my warranty too..

[@SkyhookStudios]

Philipp Schaad if you remove the cables from the exhaust and the servo motor, then there will not be any engine light. For warranty issues, you will have to put them back or it will void.

[@djnikimatteomatteo9291]

Do I still need to buy a servo buddy

[@alpha1k-]

DJ Niki Matteo Matteo only if you want to remove the servo altogether

[@GetHighspeed]

No error code?

[@SkyhookStudios]

As long as the servo is plugged in, no. There is nothing double checking for proper movement beyond the servo. Normally there would be a corresponding sensor at the valve in the exhaust to confirm that the valve moved where it was supposed to. I assume because of the high heat, there isn't one.
