The acid bath may open leaks in the tank if the rust was very severe, so be prepared. I would recommend doing the whole process outside (for fumes) with a hose handy for diluting any spilled acid. The liner may end up a bit lumpy looking, but this is okay, the tank at least sealed and protected. Pour in liner according to its directions and follow remainder of directions from liner.ġ0. Immediately proceed with the next step.ĩ. Do not let all the MEK evaporate completely because oxidation will begin right away. Any small amount leftover will only slightly thin the liner (which contains MEK anyway). Immediately clean all inside surfaces with a little acetone or MEK and empty out as much as you can when clean. When all the rust is gone, dump the solution and rinse the tank very thoroughly with water. ![]() The tank should look brand new inside when done.Ĩ. Look through the gas cap carefully with a flashlight to check the progress periodically. I let the whole tank sit with the acid solution for a total of about an hour and a half I think. Then switch to another side for ten minutes. Set the tank on one side for about ten minutes. This goes for the acetone or MEK as well.ħ. Pour the solution into the tank, taking care not to get any on the paint, unless you plan on repainting. I mixed half a gallon of acid with half a gallon of water for my tank. This is available from most hardware stores as a 20% solution, so just dilute it with an equal amount of water (always add acid to water, not the other way around). Mine didn't need this since it had only small flakes of loose, powdery rust.Ħ. ![]() If the tank has large chunks of rust, you may want to add BBs (or chain, etc.) and rotate the tank for a bit to remove the worst of it. If the tank sat with gas in it that evaporated (like mine), clean the tank with a little acetone (or MEK) to remove the worst of the varnish left by the gas.ĥ. A wood or metal stop might be more appropriate, but this worked fine for me.Ĥ. I sealed them on with cheap silicone sealant (which comes off fairly easily afterward). I fashioned two stops using a couple layers of heavy corrugated cardboard wrapped in duct tape, cut to fit and held in place with the petcock screws. Remove the petcocks and fuel filters from the tank.ģ. Empty the fuel from the tank if it is not already. The kit basically has three parts: part A (acid), part B (MEK), and part C (the liner).Ģ. You can also order the complete tank prep kit for $26 if desired, but in compliance with CBMMA, I took an even cheaper approach. Available at Dennis Kirk, part #3160, $14. Motorcycle Gas Tank Rust Removal Techniqueġ. I thought about spraying it with water, but since tanks are proned to rusting I decided to ask you guys first. So after a long winded description here is my question, How do I clean out the tank to remove the junk I presume is in there. But thinking about it, i figured since i have a couple of days off I'd take a look at other things.Ĭhanged the oil, checked the chain and electronics for frayed wires, and to swap the air filter I had to remove the tank. So I replaced the fuel filter and everything started up just fine and ran normal. I checked the fuel filter and was absoultely surprised by the amount of junk in it. So I called a friend for a pickup and we loaded the bike and off we went.Īfter talking about it for a few minutes we guessed that the bike picked up sludge from the bottom of the tank. ![]() It ran really rough for a few minutes, I let it run and when I tried giving it throttle it would stall. After getting gas put back in, I tried starting it up and it would fire only when the choke was in. ![]() But it bogged down again, I pulled off immediately to the right shoulder. The bike was fine for about a mile as I was nearing lawrence to get gas. Anticipating this since I knew the range of the bike was around 180 m, I switched to my reserve pickup. The first time I ever let the bike run out of gas, riding down 237 to hook up with some people for a saturday ride, i felt the bike lose power. Well I found a lurking problem with my 94 XJ600. ![]()
