Painted Carbs

[Guest]

Here's some I just finished. Not painted...just cleaned up and the bowls and tops polished.

Great work! I never did chime in here but I am quite happy with my paint job. I just wish I didn't have to keep removing them to tune them right. I guess a few nicks just makes them fit in with the rest of the bike!

Renobruce,
I don't know if you got my PM I sent a few days ago but I'm reposting here as I have a few questions about the great work you did.

I have ideas in my head about making my bike look a little better and right now I'm toying with what color I want to paint the tank and side covers. If I wanted to paint my carbs, what are some of the tricks you didn't mention in your post on how to do it?

I know I need to tape off any orifice but is there a specific way to do it? Do I just wad up a piece of tape and put it in?

Do I need to hold each carb up by something as I paint it or can i have them laying down and do each side at a time?

Although they were dipped in May and I replaced the orings then, should I replace them again if I paint them?

How do I know if mine are already painted? I don't think they are due to the greyish color already there but is there an easy way to tell?

When boiling to clean them, is it a hard rolling boil? You said to leave them in for 30 mins, is that an estimate (can go longer/shorter) or a fixed this is what you need to do time? Although the oil is in the water, won't some of it still stick to the carb (even holding it down with the wooden spoon) when you dump it out? Do you dry them with a towel or will a hair dryer or air compressor work?

What's the difference between caliper paint and the exhaust paint I'm going to use on my pipes to get rid of the acid etching from the PO?

I use painter's masking tape. Flat surfaces get taped over, then cut around the edges with a razor blade or exacto knife. With orifices and holes I shape the tape into a tapered cone and insert into the hole, then fold over the top so no paint gets in.

Do I need to hold each carb up by something as I paint it or can i have them laying down and do each side at a time?

I hold them up with small pieces of bailing wire. That also helps when I bake them in the oven....I hang them from the oven rack.

Although they were dipped in May and I replaced the orings then, should I replace them again if I paint them?

You shouldn't need to replace the orings, but you will need to strip the carbs back down.

How do I know if mine are already painted? I don't think they are due to the greyish color already there but is there an easy way to tell?

If they were painted, the dip would have most likely taken the paint off.

When boiling to clean them, is it a hard rolling boil? You said to leave them in for 30 mins, is that an estimate (can go longer/shorter) or a fixed this is what you need to do time? Although the oil is in the water, won't some of it still stick to the carb (even holding it down with the wooden spoon) when you dump it out? Do you dry them with a towel or will a hair dryer or air compressor work?

Not an exact time...30 mins. seems to be long enough to heat the parts and leach the oil out. Yes, a rolling boil. I then drain the water off, then I scrub again with dish soap and a toothbrush and rinse with clean hot water. I then use compressed air to dry them and remove any water in the orifices.

What's the difference between caliper paint and the exhaust paint I'm going to use on my pipes to get rid of the acid etching from the PO?

I haven't seen much exhaust paint that is glossy. There might not be much difference, but I'm not sure. One difference might be the heat rating of the paint. I am now using VHT caliper paint for the best results so far. It's rated at 900 deg. F.


I hope that helps. Let me know if you have any other questions.

I know this is an old thread but I found it extremely helpful. My carbs aren't perfect but they turned out so much better than they would have with out this thread.

[SVSooke]

Thanks for reviving this threadNow I know I should have taken my carbs apart to paint them.

I have to do something with mine, they're disgusting. They won't be as pretty as any of these though...

I have to tell ya they look incredible! Can't wait to get them on the bike!

 

[makenzie71]

So I sold them on ebay....for $1,045.00! :-\\\

I got this far before I dashed to garage and started disassembling my three sets of VM29's.

Renobruce,

I know this is an old thread but I had a question on the painting procedure. Everyone says to dip the carbs after disassembly. In many of the photos I can't tell if you are removing the arm that controls the throttle valve before you dip and paint. Some seem painted and some do not. Isn't there an o-ring behind that arm on the shaft and if so, wouldn't dipping eat that piece of rubber? Every time I have dipped something and left rubber on it , it ate it right up.

Thanks for the clarification,

Sci85

I don't remove the shaft. I don't think most others do either. It can be very difficult to get the caps of the ends, and the screws off the butterflies. I've never had a problem with that oring, but I have since moved on from the dip to ultrasonic.

That's probably the better route. What do you use for cleaner?

I tried my first attempt at polishing today since it was so nice outside. My carbs have some pretty deep pits in them so I wasn't sure what to do about those so I just hit the wheel anyway. This is after the first polish with the black stick and the sisal wheel. Would welcome your feedback. Some turned out a little shinier than others.

Somehow I lost the brown stick so the next step will have to wait till tomorrow doh! Also need to get something that will get into those little nooks. How long do you spend working the piece with the emory material?

Thanks,
Sci85
