To be sure,take the old bearings out for powder coating ,a heat process,but must mask off the bearing housings.Or leave them in as masking but the bearing seals will be ruined so you'd have to scrape off any powder coating to get them out.New bearings on my old girl are cheap and standard.Brute force with hammer and drifts worked for me.New bearings= peace of mind.
If it's paint then no heat involved but is an inferior coating.

So the bearings are a standard type? That makes it a lot cheaper if I don't have to buy OEM from BMW in the US.

Today my son and I installed a new (to me ) loom and wow does it look better.

We also examined the bits from inside the tank because one of the few remaining issues from the PO and the loom is the fuel pump connection.

So it seems to me the fuel level sender is toast, also that the fuel filter is not oem which makes me think the pump isn't either.  I don't know whether to cut into the new loom - wich I am obviously loathe to do -  or try and fix it so it uses the original connectors etc.

How much should I worry about this?

I am looking for a used fuel level sender but they seem to be as rare as rocking horse doodoo...

In '86 they certainly were.I presume yours are also similar but I have heard of more recent designs having bullshit added complicated weird tapered roller different either side bearings,which caught me out when trying to post authoratively about it....I could still be wrong.Replacing mine was easy.They fail slowly in my experience whining and getting hot untill the last bit and then they sieze or the cage colapses and shag out the housing.You'd deserve what you get if you didn't notice all that in time.
Proceed with confidence!..but use a reputable bearing supplier.

I am going to try and clean out the inside of the tank.  After a few internet searches I am going to go with vinegar and see how that works.  Here are a few before shots, it is pretty bad but not as bad as some I have seen on here so I will count that as a win! No idea what fuel pump it is but it seems to work fine and the MacGyver to hold it in the vibration damper looks solid enough

It doesn't look too bad at all.

i use pine-sol cleaner to soak motorsickle carburetors--it loosens and cleans all the grime and residue, plus it smells good.  Vinegar might work too although i've never tried it.

It looks like you have a hole developing in that problem area below the fuel pump--and it looks like it's been welded or repaired before.  That left side lower seam area is prone to develop leaks over time.

Good eye - yes it has been repaired there in the past, I am about to send the tank off to be stripped and painted so let's see what horrors that will reveal.

Been a day of cleaning and prep so far.  Part of that has been working out where and how to mount the K1100RS fairing I am going to install on my K100 RS.

Can any 1100RS owner please confirm for me that this tapped hole on the rhs of the engine is for a fairing mount?

Does anyone know the part number of the hose in the top of the air box? On MaxBMW the fiche just has the whole thing as one very expensive piece when all I need is the one hose.

The one on there is all cracked and the end has rotted away completely.

Can you post the diagram and indicate the "one very expensive piece?" I see a hose for around 27USD in the MAX diagram.

Here is the fiche from MaxBMW - I thought the hose I needed was no 9 - 13 31 1 461 972 - $23.15 but it isn't, I know I ordered one! The hose I need has a strange inbuilt seal in the middle where it goes through the body of the air box.  I have looked fairly carefully and can find nothing like it.

Have you removed the hose from the airbox?  Are you sure that you aren't looking at a grommet?

How does it differ from the parts shown in this post? It might be your existing part has been replaced by the one you ordered.

Fairly sure - and it is a different material - much more rubber than the hose I ordered which is more like a braided fuel hose type

There should be a number molded into it.  Can you see one?

All right, everyone, the part is available. Go to the Engine Mounting Parts diagram. Look at number 10. After you say, "That's not it!" Click on the diagram then scroll down the menu to number 10. Enlarge the photo and you'll see that is the part. 46USD plus change plus shipping and it's yours. The diagram is generic.

Hat's off to you Laith - that certainly looks like it - what a strange place to have it listed.
