1979 GS850g carb help

Ive been messing with this bike for some time now, I bought it sitting for a year and the previous owner started converting it into a cafe racer, he was never able to get the bike tuned for power and I’m sure it’s because of the UNI pods installed. After cleaning the carbs, adjusting timing, taping the pods, color tuning, and syncing carbs I was able to get the bike to run smooth and recover the majority of its lost power, but it’s still extremely hard to keep that way so I built ITBs for each of the 4 carbs, only for it to tune for the perfect idle but be too restrictive for power or to lean for idle and still too restrictive for power. I need a jet kit for these pods but I cannot find anything 1979 specific, only 1980-83 from dynojet. Does anyone know if that’ll work? Or if I’m headed down the wrong path? Any help appreciated.

Even though I have a 50:1 riding ratio (50 min labor to 1 minute riding), I still adore this bike, I mean, look at her.

No, that jet kit is for BS carbs. You won't find much for the 79 as it is a one year; only version
Your VM carbs are very tunable
What are your settings for pilot fuel, pilot air, pilot jet, jet needle and main jet?

How do you ride with no front suspension?

For pod use, open carbs or stacks all you need to do is simply install air corrector jets ( main air jet conversion ).
This is the guaranteed proven solution.
Leave ALL carb settings, needle position, pilot jet size STOCK and go up a size from stock on the mains.
This will cure the off idle bogging / hesitation caused by the transitional lean spot and sharpen up the power curve to the red line.

You drill drill out the main jets use number or letter, or fractional size drills. Between the three, they go up in increments of .001" inch. If you go to big, You can solder them, then drill back down.

As Zed1015 said with VM carbs air corrector jets are the solution.

Be sure the rims of the pods rubbers arent plugging any air jet holes or anything else

Purchase a set of Wire Sized drill bits. My idle jet is the next drill bit size up 15 - 16 and my mains are ? hmmm, I just pulled a Mitch McConnell...

However, my air box looks like this...

So my question is that if you're gonna stuff pods in a stock box why not just use stock filter. All this looks like a waste of time.

Use the search feature and look for JOCKEYJOURNAL. I posted a jet size chart years ago. If I don't see you have found it when I get home this afternoon I'll try posting a link

It's a factory air box... although it's not stock. It breathes a lot better than stock, obviously.
Also, it's sits in the factory location using the factory mounts. Sleeper...

May be a wste of time to you but my 844cc 750 engine actually enjoys it.

I love this forum, thanks for all the knowledge and help. The air corrector is a smart fix, I’ll be trying that as well as stepping up the main. And as for how do I ride with my lack of front suspension, the answer is I don't! I just bought new schrader valves and seals as the previous owner broke them in half installing the handlebar.
