Hello good people,
Unfortunetally my tank started to leak. I've given to tank to a pro to weld it, but it started leaking after few weeks again.
So, I will try to source one from ebay, but I'm not sure which one will fit(?) It's 1984 K100 RS.
Appologies for my ignorance, I've tried using realoem, results are as follow:
Superseded by:
16111455011 (03/01/1985 — ), nonexchangeable retrospectively
16112307468 (09/23/1992 — ), nonexchangeable retrospectively
Supersedes:
16110029225 (05/01/2000 — 11/26/2013)
Part 16111450631 was found on the following vehicles:
K589 (K100, RS, RT, LT) (05/1982 — 10/1989)
I'm just not sure how to read that. Can I source the tank with "bold" part numbers? Once I click one of those two part numbers there is a lot of options. It's a custom bike so I don't have any fairings.
Many Thanks!
Victor

The change was 04/85.......if your tank have a single mounting screw at the rear end, and the electric
connector at the front left corner under the tank....you have the early version up to 04/85.
If you have a mounting clip and post underside the rear corners of the tank, and the electric connector
at the rear end of the tank......you have the later version from 04/85 and on.

Mine leaks very slowly and seems to be "fixed" with JB weld
This stuff appears to be one of the standard go-to items for leaking tanks and is available at auto stores where I bought some more
Why not take it back to the repairer / welder once you are certain where the leak is (empty and re-pressurize and submerge like a bicycle tube or at least run soapy water over it).
I think you are very close to a proper fix.
Regards

I appreciate your help gentlemen.
Tank was originally leaking in the on the bottom "corners", both spots were welded and now they are leaking again. On top of that, it started to leak on the other side as well. Tank was slightly dent when I bought the bike, after the customisation maybe it was a bit more exposed to vibrations(?)
The guy who did the welding told me that this might be a blind chase, and it might be better just to source a "new" tank.
Unfortunately this is the old '84 one with electric connector at the front left corner, which makes it difficult to replace.
I'll give the JB weld a shot but I might have to start looking for another one.
How difficult would buying the new tank and adjusting the connectors?

Just how difficult is this (http://www.ebay.com/itm/like/380466975258?lpid=82&chn=ps&ul_noapp=true)? It took an elderly man three minutes of work.

Haha thanks Laitch, I should have said "in a reasonable price range".
I bought the bike for 1000£. There are few used and good looking tanks between 40-80£, unfortunately they are all for 85+ models.

Victor you can get aluminium solder that can be used in conjunction with a propane torch. You would need to thoroughly flush out the tank before you used the torch. Or fill the tank with an inert gas eg: nitrogen after flushing. Look it up on the net ( how to solder aluminium ). I am going to try it at a future date and will post the results.
Regards Martin.
