Advice for Bike Rust

Hello everyone,

Everyone once in a while my bike will have to sit outside. As such this has happened to my Carb.
What can I do to protect those metal pieces, other than keep them soaked in WD40 or something.

Corrosion x, acf50, etc. Or a breathable bike cover.

I'd do both. Get some corrosion x. Works wonders.

I've read of people spraying "Fluid Film" on exposed steel parts.

But I will ask if that carb had ever been soaked in Pine-Sol to remove fuel varnish from inside passages?
Pine-Sol is an Eco-Safe carb cleaner, but it also removes the rust protective Anodizing from Steel Parts.

Corrosion X looks like a great option, unfortunately we don't have covered parking at work and it is rainy season, so I didnt want to have to take the carb apart every week to keep it from rusting away! maybe once a month or so ill clean it up and use corrosion X.

Unfortunately, yes... This was a mistake on my part, I had never worked with a carb before and as someone who tried to be somewhat Eco-friendly, this was my original choice to clean it. And while it worked fairly well, the parts never quite looked as nice.

how about giving it a spray of WD40? ;-) ....after you replace or replate those rusted bits, of course.

Well, you can't replace most of the parts. I haven't found an economical way to replace them since the only way to do that seems to buy a whole new carb for like, $400.

The parts were originally cadmium plated. Cadmium is nasty stuff so you wouldn't want to try and re-plate the parts with it.

Plating the parts with copper or nickel (or both if you are energetic) is not that hard to do. It's not out of reach of the home mechanic. The hardest part is finding a source of pure nickel, but nickel welding rods seem to work well enough and are pretty available. After that, all you need is a decent power supply and some vinegar. The power supply can be as simple as a 6-volt battery, but a 13V computer power supply is better. I have used that for plating and a medium duty automotive battery charger for reverse-electroplating to clean heavy rust where the higher current is a plus. For plating, high current is not necessary and can work against you. My supply provides [email protected] or [email protected]

One important step is the cleaning of the parts. A good cleaning with detergent will take care of the grease, but the rust can be reverse-electroplated. I have used this to clean old cast iron pans. The rust comes completely off of the piece and it doesn't take very long.

A nice nickel plate would be a bling-bling thing, no?

Rustoleum works, too.

I had a local guy do all the cad plating on my carbs when I restored my Superbee. ;-)
