'82 850G? blue spark on all four plugs, valves adjusted, I'd have it running in a day.

I wish you the best with your sale!

Did you do a "bench sync" before you put the carbs back on (use light to adjust the butterflies to as close to even opening as possible)?

As Mike has asked, did you bench sync them?

Considering all, the airbox, air cleaner box and carb boots and air box boots have no leaks, I'd check the supply side, the gas side.
Have you, or considered to attach an alternate gas supply to the carbs,
probably a makeshift gravity flow temp tank. This would directly feed your carbs and eliminate the vacuum line, petcock, restrictive vent in tank, etc.
If you attempt to do this I'd keep a fire exstinguisher close by.

And please, if youre still using starting fluid, stop. Its very hard on engines in general. No need in causing another issue by using that stuff.

well ,, im at a loss myself, i have spent week on finding air leaks
i took drastic measure today , used ether with a straw, while the bike was running i sprayed the intake around the air box ,carbs, no pickup in rpm \s was found
so what ever is wrong i have to call it quits !!
this bike has taken up way to much time ./ money for any kind of ride/fun i could have
so this bike will be for sale , along with the spare motor
pretty nice bike tires are almost new,new battery, plugs , new rebuild kits( dipped,&sonic cleaned) carbs / petcock everything works except motor hahah ,,motor has been rering paint is faded i was going to paint it after got running ,
i am looking on ebay and craigslist for a bike that runs!!!!!!!!
i want to say thanks everyone for youre time and youre ideas !

I have an 82 GS850, send the carbs to me, I'll test them on my bike and if there is a problem with them, I'll find it...

update'
i decided to take the bike in to a guy who looked at the bike and said he could get it going ,
he called and said everything i did was good, he syc the carbs, set plug gap , there was a issue with the petcock, even after the rebuild a spring had broken and caused alot of the issues,
he redone the intake seals now i need to find a good petcock and valve cover gasket and rear brake master/ caliper , or kits

Glad you haven't given up on it. And 82 850 petcock should be alot easier to find than say a '79 850 (old style). Any petcock problem can cause you some serious headaches.

well i went as far as i could go with the repairs,
this guy is very mituculus,and straight foreword , plus he went to school with me, and shares my same last name although not related ,
the dealer can get a remaned petcock, 100$ found them elswhere for under 60$ so its ordered
the rear master cyl , and caliper are issues at this point, dont know wheather to get kits or replacements?
by the way the bike has been riden now , so the incouragement is the game changer!!
soon as we get the needed items, valve cover gaskets, brakes repaired, new petcock, oil filter/change, tires ,, then its on to cleaning polishing, and new paint scheme. thanks to all out here,
