Look at ‘Evap canister delete’.
Smart-moto part : PVE-052 ( no codes thrown ).

I have the Evap Canister delete kit sitting on a shelf with numerous other projects.
I was just curious to see how it looked once it was deleted.
 
I removed the servo completely today and put 2x healtech servo eliminators. Here is my 2 cents:

The sound improvement at low RPM is not worth it IMO. (I didn’t see any worthwhile improvement when I tested it unplugging the electrical cables to the servo anyway.). Maybe this applies only to my setup, as I have the 100 years model with the Akrapovic exhaust. The sound improvement maybe worthwhile with other exhausts, especially the shorties I guess…

I went ahead and did this mod anyway, based on opinions in this forum, thinking that restriction in the exhaust unnecessarily increases heat in slow traffic (or stopping for red light). Weight savings are minimal but I wanted to remove the servo anyway, thinking that the simpler the better. Also, one less exhaust component which can theoretically fail should be a positive thing. (I assume it is not a certainty for it to fail to 100% open.)

As far as the ease of doing this modification goes…. Although it is not extremely difficult, I don’t agree that it is the easiest part to remove on the bike. Remember though, I am not a retired mechanic or anything, so maybe for some people this whole process could be a piece of cake. Standing on its side stand, reaching to the low side (shifter side) from below is easy, both to remove the torx bolt and to loosen the nut of the cables as well as the cables themselves. Reaching the high side however, is more difficult. Accessing the torx bolt on the plastic cover of the disc seems to be only possible with an L shaped T25 key. Taking off the main body of the servo is easy, as the single bolt holding it isn’t tight at all. Once the nuts are loosened, and the main servo body is taken down, removing the cable anchors from their slots is much easier.

I am attaching the photo of the servo I had removed and how I fixed the servo eliminators under the bike.

I’ve recently done the same thing, maybe 6 weeks ago. Yea, it’s not ‘night and day’ different but I can hear an increase in ‘growl’ say pulling away or giving it a bit up a steep incline at low speeds. All these mods are subjective and we all value the pros/cons differently based on our tastes. I have the fishtails though so maybe that’s the difference, I love them and they are deffo staying on!

I invested in scissor jacks ages ago so working under mine is easier, a motorcycle lift would be the ultimate luxury but it’s not necessary for what I plan to do (routine oil change etc).

Forum feedback is always useful though because we all learn from doing these things 👍
 
I haven’t done the canisterectomy yet, but it is on my list.
How long did it take you to complete it MilwDave?
Scale of 1-10, with 1= easy, how would you rate the difficulty factor?

I’d give it a 3. You don't need to remove the tank but I chose to as to make the finished job complete and tidy. If you do decide to remove it, find the tank removal instructions in one of the accessory instructions. I removed it from memory and I cracked the plastic fuel line fitting while taking the tank off. I replaced the fitting with a billet part I found on Ali Express.
But it can be pretty simple. I found a kit that had a plug to replace connector on the Bosch valve that you also remove. It also had a simple rubber plug to block the smaller diameter of the two lengths of tubing you remove along with the canister.

Here is another post with some detail:

This is the last mod I performed by deleting the evap canister. I pulled the side cover off to gain access to the canister hoses. The canister slides up and off the base. The hose coming out of the valve goes into the bottom half of the air box this hose can be cut back and plugged or take it all the way back to the barb on the air box bottom and plugged it is very tight in there. The hose coming from the gas tank is in barb connected sections just behind the frame to the left of the cover is the last one. This is were I tied the 7/32" vacuum tubing approx 24" running it over and down to the old canister mount that I cut back to reuse through it to the hole just in the frame just in front of the rear wheel. you will need to use a smart moto PVE-052 plug $21 to go in place of the valve. no codes were thrown after this mod.



1/. When you refer to the “valve” you mean

the Bosch item ( small cannister approx. 1” long ) with electrical input/ wires attached on the south side and to the larger diameter hose on the northern side going to the air box. Pull hose off Bosch unit and plug hose ?



2/. Smaller diameter fuel hose has to be disconnected from top of Evap cannister and extended with barb connector/ extra hose to a lower part of frame ( a clip already exists ). Can see the hole you used.



3/. The Smart Moto PVE-052 replaces the 1” Bosch unit and plugs into the existing small rectangular looking item currently positioned “south” of the Bosch unit ?



4/. Remove Evap cannister.

This is what you need. Item #P318455
$60 for the pair.

Don't pay attention to what revzilla says they won't fit. They will fit. I've bought three sets now. Did my first and second r18s, and a buddy's r18.
This is a very easy mod and well worth it. The springs will keep the valves in the full open position when you remove cables and solenoid assembly. When I get time this spring I plan on completely removing the rest the valve assembly inside the headers and can post results and what I did

Do these come with instructions?

https://www.revzilla.com/motorcycle/servo-buddy-bmw-s1000rr-2009-2014?sku_id=1072318


Since the first one appears to be a hardware (no electronics plugging in) --does it throw an error code since it's not tricking the ECU to think the servo is still connected?

Sorry for the newb questions...

Don't need these my cables have been off for quite awhile, no codes.

No codes when looking with a obd device or just nothing on the display?

My understand was that a error code was logged and could be read by a dealer (say at service time), but no display warnings were shown.

Hey everyone! I've had an R18b since 2023. I'm not entirely happy with my stock exhaust. I drilled out dics in the baffles, but didn't notice much of a difference. Meanwhile, my neighbor recently brought from USA a used R18 with a Vance exhaust, and it sounds absolutely amazing and surely very different from stock r18. The sound is MUCH more voluminous (what you rightfully expect from 1.8L engine) and it growls even when the throttle is in a stable position. Hence you don't need to rev every time you want to hear your engine.
As we are not in contact with prevoius owner we puzzled for a long time over the reason for such a difference?
Thanks to this forum we found out that the previous owner removed the DB Killer from the exhaust and installed the Healtech ese-bm1 emulator recommended here. So the combined result is great! The good thing is that you can always roll everything back if not pleased.

By the way, other guys here are curious would the servo removal give any results with just standart fishtails?

I found little to write home about with the servo's removed with the fishtales. Whilst an improvement it wasn't enough to really notice after a bit.
