Uhhhggg!! Sometimes I hate carburators.

As soon as I can get some time to work on it I'll let you know what I find.

Did you try poking a fine wire thru the carb passages as per the GSR tutorial? I guess there are differing opinions on that.

[JTGS850GL]

Yep, poked and prodded each passage. Dipped in the Berryman's good stuff, sonic cleaned, poked and sprayed everything. It's not like I haven't done these before. Something just isn't working with these. Maybe when I get a chance to tare it down I'll find the bonehead mistake I made on this set. Hopefully tonight I'll be able to get around to it. Maybe the 24 hour dip in the stronger professional Berryman's ate away the shaft seals and #4 is pulling more air around the throttle plate.

I'm getting ready to clean my spare rack soon using the same approach you did (Berryman's and ultrasonic) so I'll be trying to learn from this thread.

I think I may have found the cause of my problems. After rebuilding the carbs, they sat on the bench for a few months waiting for me to get off my butt and install the replacement engine. unbeknownst to me, some time during that period a pesky little spider decided to take up home inside my pilot air jet. I'm thinking that I didn't notice it on install and upon initial startup the fuzzy little nest got sucked into the air jet and clogged it. Afterwards I didn't see the nest since most of it got sucked behind the jet. It wasn't till I was in the process of replacing the body and began to remove the pilot air jet from the original body that the fuzz plug fell out. I decided to go ahead and swap the body anyways just to make sure I've covered all the bases. Problem solved. Just fired the her up and all 4 are contributing well. Vacuum synced and idling nice and smooth at 1100 RPMs.

Some times it IS the easy things. Everything is back together and now I have a GS1000/1100G.

Nice!

Good to hear and congrats! I was concerned it might be this:

Maybe the 24 hour dip in the stronger professional Berryman's ate away the shaft seals and #4 is pulling more air around the throttle plate.

So I am glad to hear this wasn't the case, as I've done the exact same thing (24hr dip in Berryman's and ultrasonic cleaned with Simple Green HD) with 3 racks of carbs over the last 2 weeks and now have my o rings from Robert and SS screws so I am going to put them all back together this weekend...

[JTGS850GL]

Everything is in good working order and no issues with the dip and sonic cleaning. Really do like that Simple Green HD Pro. No issues with discoloration and really does a great job at loosening the hard stuff. Sounds like you've good some bench time getting all three sets put back together.

[mikerophone]

Good to hear. Yes I do have some bench time ahead of me. Now that it's getting warmer I need to get these bikes on the road. Got a couple of friends bikes that I am going to strip, dip and sonic clean as well. Time to re-up my Simple Green HD Pro supply.

I'm sure I'll need some sprinkler parts here soon enough anyway and will be making a trip to Home Depot...
