Painting carb tops

Postby Bill Melater » Sun Jul 24, 2016 9:17 am



Has anyone had any success painting the aluminum carb tops on their Keihin carbs and if so what did you use? The oxidation has gotten under the clear coat and the tops look like crap. I figured while the carbs are apart I would remove the remaining clear coat and paint them. I found a brass wire wheel for my bench grinder and it takes the clear coat right off without harming the aluminum. I'm open to suggestions for painting them.

Do you really want to paint them? Personally, I find that they look much better if highly polished. If you give them a good coat of wax polish after, or apply an occasional coat of ACF50 and wipe off after, they stay looking good for many months.
If you still want to paint them, they will have to be abraded first, to give a key for a good quality etch-primer, before applying top coats.

If not scratched too deeply, they polish up shinier than new with a buffing wheel. Regular cleaning and wax and they stay that way. Paint stripper pulls the old clear coat off safer than a wire wheel.

Others gave powder coated them.

My carb tops are scuffed, pitted and pretty nasty looking. The bike itself is pretty ratty. I will go through it and correct it mechanically but cosmetically it has seen its best days. What I cant polish will get painted black. At best it will see the road as a stripped down Goldwing.
