Cleaning Carbs with Ultrasonic Cleaner???

Hi All,
I have cleaned a lot of stuff out of my Carbys manually and with little compressed air and mainly a bike pump
All works fairly good, starts easy with choke on full, just idles on half choke (right hand assisting) until warm.

Maybe some of the idle circuit still has some crap in there.

So it goes BUT I'm thinking I would like to do them again using Ultrasonic Cleaning?? as I have been reading that they are pretty good at getting all small passageways throughout Clean and hopefully will then idle on half with no assistance.
Do I strip down carbys (not separating them) pulling all jets out, floats all those little bits off and just put them in the Ultrasonic Cleaner?

Is this a good idea or going too far??
or do I put this in the "if it ain't broke don't f..k with it" basket

Cheers Alan

I learned the hard way to stick to this you said: 'if it ain't broke don't f..k with it'!  :rofl:

Only warming up on choke is problematic or it has no idle when warm also? If it idles when warm, stick to the above mentioned line.  :nyam1:
Until recently I had a problem with warming up on choke, too. I had to hold the throttle for a while until it got warm enough for choke to hold it. Interestingly, after I did the valves (they were messy) and vacuum adjustment that choke problem is gone.

Alan, they are the bomb.....however, to get a heated ultrasonic cleaner with a big enough basket to hold a rack of carbs will be a major investment.
The smaller (heated) units that will hold a single carb is more reasonable. It's no big deal to separate the carbs. You want to change to o rings on the float bowl T's anyway.

If you have a group of fellow riders who can also use the unit, or if you own multiple bikes or other equipment to service, I'd say go for it. If it's just you and your FJ, I'd say leave it alone.

Alan,

Breaking down the carb rack is the proper way to ensure they are clean. As pat said getting cleaner large enough is expensive. Also, breaking them down will ensure any larger debris stuck int he fuel transfer tubes gets removed as well.

I offer this FJ11-12/XJ12/XJR13 S/S Screw & O-Ring Carburetor Kit which covers the complete carb set with new o-rings and screws.

Just a bit of lite reading in those 4 pages but links didn't work, so taking your lead with information you found and Google searched "the motorcycleproject" and found so much more lite reading

So it looks like Breaking them down is the way to go and if its 30 years before they get pulled apart again it probably won't be me doing it.
