Picked at a little rust spot, ended up with this:

Any ideas?
 
Get a new one on Ebay :P Or, take it to a radiator shop. they can patch it, and clean the inside out for you for relatively cheap. Looks like someone had a problem with that before you got a hold of it judging from the body filler under the paint there...
 
Well, at least you don't have to worry about whether your gas cap vent is working properly. :D

Nice one.:rolleyes:

That tank looks like junk to me. If the metal is thin from rust in one place, there are other places waiting to break through just around the corner.:hand:
 
Nice hole :p. Depends on what you want to do with the bike. If you're just looking to flip it, the POR-15 sealer kit comes with cloth that can patch that hole. If that bike is a keeper, get a new tank.
 
strip the rest of the paint off with a wire brush on a angle grinder this will open up any other holes (which is good). If there are dents take it to a body shop first they will pull the dents with welded rods. Then take it to a radiator shop, they will patch all the holes and seal it for you. Should be fine after that. Then just get it painted.
 
That tank has serious problems my friend. Pin holes are one thing, but that thing has seen better days. Probably better off finding another one on flea bay. They may be few and far between but they are there. Just be patient.
 
Yikes!..... If the rest of the inside looks rusty, like you can't see any more shiny bare steel, then it's junk. If it's only that one spot as if water had accumulated right there, then it can be repaired at a radiator shop as mentioned before.
 
Some 22ga sheet metal and a little brazing action and that tank is hold fuel once again. You will want to clean it ( I use a hand full of drywall screws and some MEK. Shake like hell and repeat til no little flakes of tank sealer comes out. Or til the MEK is clear of rust color) Braze the preformed piece in, let cool and tank seal. If you dont know how to braze any radiator shop can do this for you.
 
I bought a 1980 GS 1000E that had a 1981 GS1100E tank on it. Put that tank on that 1000, it fits fine, but any GS expert would recognize the incorrect tank. It's been painted, looks nice. It's in Texas, for sale, if anyone wants a very fast and decent looking GS1000.
Still sitting on the second GS1000, trying to find a good tank for it.
It's ready to ride except for the lack of a tank. Got one?
 
Cant tell from the pics but it appears that hole may have been a low spot where water collected. The rest of the tank may be fine. Ive got some poly sulfide (fuel tank sealer), commonly known in the industry as pro-seal, that I would smear over that hole. Let it set up a couple days and it will hold fuel.

There are a lot of holes of various sizes, maybe thirty or so.
The whole thing is really quite rotten.
That one could be patched and used, but I'd rather just hold out for a nice solid tank.
It's not like I can't ride while I wait, if it was my only bike that would be a different matter.
 
hole in tank.... dramas.....

hole in tank.... dramas.....

hi guys ... hi guys a few years ago i had pin hole in my 1980 gs1000e tank along the side stand side seam and around the seat section anyway it went back to metal and then i used loctite cold weld 2 part mixture...it worked o.k. for a short time and then more stuffing around and finally i got another better tank and had it plated by a sheet metal worker who migged the tank,, no leakes,, then finally i was lucky on ebay to win a red/white 1000s tank in superb condition and i also keep the fuel full in the tank not 1/4 or 1/2 but always full of 98% unleaded and no more problems and my baby runs like a dream i cann,t stop grinning,,,, hope this helps you regards david :):)

As a matter of fact I have two of em. One of em needs bodywork(dents) and the other one is similar to the one in your post but about half the size.
Been thinkin about how to repair it.

Thank you for expressing my ideas so well!


I would take exception to the use of MEK, however, as it is dangerous stuff to be breathing at any time, and in a closed environment it can do you serious harm..

The most common chemical is probably a solution of phosphoric acid, which tends to dissolve rust and leave a black coating behind. POR, I believe, uses this. A weaker solution is found in CLR, and a gelled version in Naval Jelly.


Wear rubber gloves with any of these, and preferably an apron as well.

ALWAYS do the work outdoors.
