Hi!
I work with the installation of the exhaust system on my R11 serie 4/5. Is the muffler after elbow pipe also attached to the footboard? Or is it just a bolt through? On the pictures I have it almost like it goes a bolt through the exhaust pipe which is screwed into the footrest underneath. Then with a spacer in between. Can anyone give me an explanation? Preferably with a picture or two.

Greetings from Norway, Frode

Which parts do you have? 4

Which parts do you have? 4 and 5 are different exhaust system and fixing is different. Can you show photo?

I hope someone else can

I hope someone else can answer and show photo’s for this, I only have S5.

The earlier R11 exhaust looks the same as the R62 etc and that has a pointed bolt that goes through both the silencer and exhaust pipe. This holds them together and screws into a threaded part of the running board at the front and rear. I guess the S1/4 should have these threaded spigots dropping below the running board to hold them without spacers, the S5 running board does not have these threaded spigots.

Hi!

Thanks for the reply. It was just like I thought they would be screwed up into footrests.

On these models the

On these models the footboards are an essential part of the exhaust system. I have found that, if you have any need to remove the exhausts, it is much easier to remove the entire system, including the footboard, as a single piece. Getting the individual pipe, muffler and floorboard holes to line up, while lying under the bike and trying to get the screw through them all, will increase your vocabulary by 50%. It's way easier to assemble it all on the bench.

Hi! When mounting the exhaust

Hi!
When mounting the exhaust on the left side of my R11 serie 4, the "stick" for fixing the spring to the central support come in conflict so I can not fasten the rear support under the footboard.
Have some of you experienced the same?
How have you solved it? Cut of the stick and moved it to another placement?
Any advice?

Greetings, Frode

hi Frode It may be worth

hi Frode

It may be worth checking your stand spring mounts are correct, so can you post some photo’s showing your spring position mounts on the main stand and the battery box also where/how it prevents fitting?

Hi!Sorry for my late reply.

Hi!
Sorry for my late reply.
I think I've figured it out, and that the spring mounts were not correct. Now I can easily fix the rear screw hole on the footrest.
But I still have challenges... When the stand is in upright position it comes in conflict with the tail pipe were it is attached to the frame. How do you guys solved this? Have you custom with a spacer between the frame and the rear exhaust tube? Or have you done so the stand can not go so far up in the upright position that it conflicts with the pipe? Another possibility might narrow in the stand so it just goes beyond the frame, and accept some spacers to build out exhaust tubes somewhat relative to the frame. Should become happy if someone took the trouble to explain how you have solved this, and document with a few pictures of the stand in an upright position. It is BMW R11 serie 4

Frode, I believe the stand

Frode,

I believe the stand and battery tray with the spring mount are the same on S4 and S5 but unsure if any of this other information about mine will help.

The “tang” to operate the stand on mine sits into a depression under the left silencer preventing the stand touching the frame. As you can see the spring is very close to the frame but not touching in both up and down stand positions. The foot of the stand comes close but does not touch the frame when up. The “tang” on my stand is not original, the original being broken off many years ago and lost.

It is not unusual to have to make alterations to new items bought for any of these machines, my silencers had the mount brackets lengthened and then also spaced away from the frame.

My guess is your stand should be stopped from hitting the frame probably with the operating “tang” contacting the underside of the tail pipe. The stand feet (if allowed) would just pass equally each side of the frame before catching on the frame sides.

Hi! See photos of my test

Hi!

See photos of my test assembly.
- I'm worried that the stand is too close to the ground
- If I put on longer spacers between the frame and exhaust to get it higher up, I think it becomes unnaturally large distance. It suits neither particularly well ...
- Can there be an opportunity to try narrow the stand to get it closer to the frame.
- Attached for spring between the battery holder and stand will not fit when the exhaust system gets too close frame ..

Should I just accept it as it is, or what do you think I should try?

Regards, Frode

Your stand looks like a new manufacture and possibly over wide compared to mine. Mine measures 250mm across the widest part of the feet, and 200mm internal across the feet. What does yours measure?

I think the extra width you

I think the extra width you have on the stand feet are the problem. The photo’s of mine show the feet in relation to frame when stand is up. The stand does not ground in this position when riding the bike.

The stand is very close to my silencers but you should have more room with smaller diameter tailpipes. Your photo looks to show enough room for it to fit.

Do you have the rear footrests? The footrest would act as a spacer of approx 20mm. Looking again at my silencer, it would locate on the same fixing as the footrest and not need the spacer. Sometimes I do not see the wood for the trees!
