So I've got a 95 ZX6R. I got it after been sitting for about 4 or 5 years so the tank was Rusty and carbs were gummed up. Carbs cleaned up pretty easy but I was having issues getting the tank clean. So I used muriatic acid.
I thought I had the tank clean before I hooked it back up but evidently not. So I got some erratic acid inside the car bowls and the carburetors and it is causing havoc
The bowls are almost filling up with oxidation stopping the floats, the carb necks are getting it to stopping the throttle plate from opening.

I've tried everything I can think of to stop it. I've used carb cleaner, I scrubbed them, baking soda, I soaked them in a cabr cleaning solution that's in a paint can. Seems like the little bit that got in there would wear out eventually but it doesn't seem like it has really worn down at all maybe a little bit but not much

I'm at my Wit's End and I have no idea what else to do! Anyone have some advise or even a guess about something i can try? Thanks in advance!
Ill post pictures soon

The only way to neutralize acid, is with a base compound. Once that stuff is in the pores of the metal, it's extremely difficult to get it all back out. Very similar to seasoning a cast iron pan, or a Wok.

If you could put the thing in an ultrasonic cleaner, it might be possible with time to shake the last of the acid out of the metal's pores.

If you're still getting lots of debris out of the tank, I have to think that it's not anywhere near as clean as you seem to believe.....

Pictures always help in this sort of situation.

You might want to start looking for another bank of carbs to rebuild, just in case you can't get this to stop happening.

Wander if baking soda in an ultra sonic cleaner would help any? Seems like I heard baking soda neutralizes muratic acid. I think.

The trick is matching how much acid you need to neutralize. My high school chemistry classes taught me that when acidic and basic chemistry combine, the result is water, and a salt. If they are in equal measure.

I've seen people trying to clean a 500 + gallon aluminum tank which had been contaminated with outboard motor two stroke fuel. An earlier attempt to use oven cleaner left it permanently contaminated with caustic lye. That tank was still nasty more than 10 years later.

This might not be as bad, but it definitely sounds like a gift that will keep on giving.....

Just pour a bunch of gasoline over it. Then set it on fire. That should fix it.

My Navy experience with Aluminum has been that it tends to corrode easily. Practically everything used by the Navy which contains aluminum also has a surface treatment that limits corrosion which then has primer and paint applied over it.

Does anyone know if alodyne or any other conversion coating process is used on carbs,etc?

seems obvious that the forks and customer visible parts have to be treated in some fashion

When we toured the Japan factories I remembered some kind of process in the alluminum plant. I wish I was a little older when I went and paid more attention to the “geeky” stuff. But I do remember the last step in the production was some sort of dipping process for all the aluminum parts. And then they went into a dry oven assembly line. Back then Honda had just went aluminum frames on dirt bikes and I was racing for Rockwell Honda then and hated those frames so I paid attention to that aspect. I will ask the old man tho he probably remembers the technical stuff better than we. And I have welded on the aluminum and it’s a pain in the ass to get it clean enough to weld good. All aluminum is but motorcycle stuff tends to be more so.
