GS1000 Gas Tanks

[Simmons1]

Other than the emblems, does anyone know what the differences are between a regular GS1000 fuel tank and a Wes Cooley tank.

My Wes Cooley tank is at the painter and according to the painter has a minimum for 50 pins holes along the seems. I am looking for another tank to send to the painter.

Thanks

Both '79 and '80 GS1000 E/S tanks are mostly identical apart from the badge mounts on the E models, which I believe some have removed and/or filled prior to paint. Of course, '78 tanks (Skunk) will sport indents.

Edit: as someone pointed out in another thread, petcock, location, and bolt spacing is different on the above mentioned tanks.

The 79 and 80 tanks differ with the petcock locations. The 79 tank won't work on the 80

Prep and coat the interior with POR 15 or Caswells liquid liner. Then paint

Thanks guys. My bike is a 79. Guess I would need a 78 or 79 tank. The tank has had POR 15 in it for about 15 years already. Recoating is probably not a good option at this point with out removing the POR 15 and starting over again.

What my process is for pin holes.

1. Mix up some JB Weld KWIK and smear a coat along the seams. Not too thick but thick enough to fill the holes and allow for some sanding after it has hardened.

2. Do either the Caswell 2 part epoxy tank liner or POR 15. Ive used both and find each equally to be quality liners.

3. Sand the JB down carefully and leave a little over the holes. Now your ready with a well sealed tank to be painted.

+1 These tanks are too hard to find and are getting very expensive when they do show up. I'd try repairing it.

You might also consider taking it to a radiator repair shop to remove the old liner and to re-seal it and solder the pin holes. While your tank is in the prep stage anyway, this is always something to think about because the boiling process ruins any paint, but delivers a clean and solid repair. Radiator shops can restore stuff that looks beyond hope sometimes.

I use a local https://www.gastankrenu.com/ shop.

All they do is gas tanks. Chemically dip them, weld them, pressure test them and then coat them. As I recollect, if they can't fix the tank, there is no charge and they warranty their work for life.

Look like I have one near by, but their site doesn't mention MC tanks. Did they coat the outside of your tank like they do the auto tanks?

I've had them do only the inside and do both the outside and inside. My local guy is easy to work with.

I emailed them and they say they will do MC tanks.

I have been looking for a place the can reseal motorcycle gas tanks that have tiny holes along the bottom where the halves are joined and crimped. Does this sound like something your company can do?

Yes

[Simmons1]

Thanks for the info on the place that repairs tanks. The closet place that does them is in Houston. I plan on getting my tank back from the painter, getting it repaired myself and then returning it to the painter. I will let you know how it turns out.

Stripping out the old liner is a pain. Heavy duty methylene chloride paint stripper works best but it's really nasty stuff. MEK eats the liner up too. Problem you have is what to do about the pinholes with these chemicals inside? Maybe that radiator shop boil out is the way to go? I'd talk to them anyway. If you can get the old liner out then moving to derusting is next. A large tub (garbage can?) where you can submerge the tank completely works well. A couple gallons of Kleenstrip Etch and Prep from Home Depot along with enough water to cover will do the derusting trick. Rinse with water followed by some alcohol to dry the tank as quickly as possible to avoid flash rust. To seal I'd use Caswell's tank sealer. It's super thick, like honey, and will give the tank some strength and reinforcement after you are done. I did an old GS1000 tank with that and afterwards it was SOLID...and heavy. Some tape on the outside of the tank to seal the pinholes will keep the sealer inside where it belongs.

Good luck
