Did he blow up the tank??? Is he now missing body parts?
Let's hear the rest of the story!
Certainly for short term. I often drain fuel from my MC into the snowblower in winter, then top the tank off, keep it fresh.
Really any acid will remove rust atleast some, then it has to be flushed.
I want to know about this WD-40 eating metal thing.
So where are you people dumping this stuff? A big drain, hole in the ground, toilet...?
The vinegar/rust combo?
I have lost 1/4 gallon to the dirt in my back yard through sloshing spillage during the siphoning/draining.
But I still have 2 3/4 gallons out of 3 gallons.
Drain tank back into bottle and reuse.
twenty too many
I've got my 19 litre R80GS tanj uib storage. Left the taps open and the caps off. No I am worried it might still corrode. The tank is lined with some red anti-rust paint from the factory. However, this stuff tends to wear from the gas filling nozzle.
Now I just remembered that I've been given a spray can of this stuff some time ago. http://www.prolan.co.nz/about.asp It's a lanolin spray made from sheep fleece, well, it's from New Zealand.
Can anyone see an issue if I generously spray it into the tank? Cap on or off (afterwards if course)?
> bump <
Now I have a used tank I just picked up. Looks like rust in the bottom.
Got vinegar, got nuts, bolts, drywall screws, you name it. So-
After the tank is cleaned out, do I just put gas in it? Don't I need a lining? A Brit bike friend swears by this Caswell stuff.
Do I need a lining if gas is kept in the tank?
My GS began leaking from rust-through on the bottom seal 'bout 15 yrs. back. I did the 3-step Kreem treatment to it with great results. This summer the rust is starting to eat through the Kreem and the steel and the garage smells like gas. Bad news.
There's a product at auto suppliers called seal all for gas and oil tanks.Apply to the outside as a spot treatment. Add fabric or mesh for larger surfaces.
Very successful results. Clear and it works. Hardens and is paintable.
It's in a tube, looks similar to shoe goo, but gets harder.
I wouldn't coat a gas tank inside unless I absolutly had to. A cleaned up tank, put back into action, with gas in it, and a fuel filter, would be better than a sealed tank done wrong.
I'm calling bullshit on this one...!
I've been using WD-40 for 40 years on steel, aluminum, pot metal, control cables and sometimes on auto paints but I've never heard any verifiable reports of it damaging anything. :huh
In fact, during the several years that I lived in the North East and had to store my bike outside, I would spray the entire bike down with WD-40 a few times each Winter, clean it off in the Spring and keep riding.
PS: I drain my tanks, let em air dry, leave the petcocks and caps off and store them on a shelf in the garage. The water heater keeps the air dry enough that rust isn't a problem, even over several years of storage. Rust is usually a problem when moisture is allowed to accumulate but even the smallest amount of circulation in a dryish environment will keep things OK.
Whatever you choose to do, REMOVE the petcocks!
keeping them in and closed will guarantee that any moisture has a place to settle rather than escape.
I prefer electrolysis for removing rust. No nasty chemicals, no coating needed, gets all the rust, doesn't promote future rust. For storage I use a small cloth bag filled with desiccant in a sealed tank.
Interesting stuff here. I've been storing my tanks with some oil in them and I turn them over every 9-12 months. I guess maybe it would be better to take the petcocks out and just let them sit?
I worry about the humidity here. It doesn't take long before my boots and gloves are covered with mold -no air conditioning.
Let a strong solution of molasses sit in that rusty tank for a day or four, pour it out, rinse it well, and it's shiny. Done it. It works.
Better put something oily in there right quick if you live some humid place.
Just found this thread too, have been looking for the best and cheapest way to manage the rust inside the tank of the FREE BSA D7 I am trying to get back to running.
Loose rust that I shook out of the tank when I took it off.
Below is a good link that i was going to follow to cure a small leak in my '89 R100GS tank.
Now having read this I'll try the vinegar first and perhaps I wont need the electrolysis
how about vinegar and electrolysis together ???
I have 3 tanks on the shelf with petcocks and cap off. I don't think they're doing too bad.
I am in the process of stripping and painting a large /6 tank. It is sitting in the "well ventilated" portion of my shop. My brother called me last night to tell me the roof leaked, and where do ya think it leaked? Right on my tank.
