I have decided not to do this myself. zero time for it. However, if you are in the UK, or don't mind shipping your carbs there, I recommend these two businesses. I have dealt with both of them for a long time. They do full reconditioning as well as all the surface treatment. Harpers Ultrasonic, Matt also offers a ceramic painting service, these ones in black. and they did mine in silver. Vapourworx Ben vapour blasts the carbs as well as all the extras.
@kiffsta does pretty well with his wet blasting. And a mechanic friend of mine mixed half and half degreaser and water in an eBay-special ultrasonic cleaner and the carby cleaned up nicely.
I am not detracting from Kiffsta's blasting service and I am not recommending that Aus customers send their parts to UK to be vapour blasted. I am just talking about two businesses that do total refurbs on carbs. If anyone is interested it might be useful information. Having done full throttle shaft rebuilds on both Mikunis and Keihins, I don't think it is a good idea for the newbies to jump right into that task.
I didn't mean to detract from the 2 businesses you shared, those pics show they do some awesome work, just adding some other options for those on a budget happier with a lesser finish. Those ceramic painted carbs look very nice - definitely the go for a show bike.
@ShaneP I think it is less about the finish and more about those companies doing a FULL Refurbishment including re-plating when needed. It isnt just "show bikes" that want this sort of service. Being on the SOHC forums in the UK and the US there are many of these that are being done as full restorations, to be used regularly and they use these services. Carbies, especially multiples (2, 3 or 4) need more than just a Keyster set in them to operate as they would have from the factory.. hence the service these companies provide... entirely different to what @kiffsta does.. It isnt for everyone but it is an option for those with bikes that warrant to spend.
The degreaser in the ultrasonic cleaner cleans them fairly well, too. Well, not nearly as well as those @maelstrom mention, but more internal cleaning than wet blasting - still impressed by the finish from wet blasting.
