CB750 Carb Rebuilding Service

I need the carbs on my CB750 cleaned and it probably wouldn't hurt to rebuild them. I could probably do it myself but I rather leave to the "professionals". I'm in Southern California and am having trouble finding someone to do this. I don't mind shipping them where ever to get the job done right and for the right price. Anyone have suggestions?
Thanks for your input.

The only issue I have with that link is that teh guy talks about using soda blast to clean the carbs which is great but doesn't talk about cleaning teh passageways. If he doesn't use an ultrasonic cleaner, then there's a good chance your carbs are no more functional after "cleaning" than before. They would look pretty though.

Go to someone who will ultrasonically clean your carbs. I have done a couple of sets for DTT guys.
 
We have a big ultrasonic cleaner at the shop; PM me for details.
 
Hey Rich, you trying to hustle my hustle? If you can do them cheaply, go for it. the 295 wasn't too bad on that site but no mention of the essentials - not so much.

Once they are clean, get a can of spray cleaner and spray each passage in the carbs and compare all 4 to be sure they are all the same. You can't just spray all the passages in one carb and then repeat on the second etc unless you remember exactly how each one flowed/sprayed.
 
We don't normally blast carbs to make them look pretty. We use ultrasonic cleaning. Is someone is going to last carbs with any media, check to see if the then clean them in an ultrasonic unit afterwards. Any carbs or engine parts we blast always go into the ultrasound after words.

Even after believing you have thoroughly washed and blown them dry with high pressure air afterwards, you would be amazed at just how much superfine grit ends up at the bottom of the ultrasound even after you had done all that. Most of the time, after ultrasonic cleaning, the carbs come out with an appearence very close to original.....and polished/shiny was not the original appearence.

No sir - in fact, if they get sent to Charlie, I'll probably have to do it and he'll get the money! ;)

nadores: since you didn't say WHAT cb750 I will through in if it's a DOHC model to give Pistol Pete http://www.oldwings.com/index.html a shout at 8six5-6oh7-ate179 or petesgl@comcast.net He has built an excellent reputation for his work on GL carb racks and I can tell you from personal experiance the GL1100 and CB750 on my two '81s are almost IDENTICAL... just arranged inline instead of on a square plenum. He also has built his own CB750 so I know he is well versed in them.
