OEM main jet size in '83 KZ1100?

The engine runs fine, but seems to want to load up a bit at lower RPM, which is understandable IF the jets are too large - in which case I for sure want to get the right ones in there before going back to the OEM airbox - so what IS the right size OEM main jet for these carbs?
Related question, the USA bikes came with a fixed position needle clip, whereas the offshore ones have several available clip positions - can the adjustable needles be installed in these USA carbs - and is there any point?
Help or comments?

Thanks for the info - and hope you enjoyed our part of the country!
What you say makes me wonder exactly the difference between the 130's *I* have with pads and 4to1 exhaust, and what the 122's in YOUR setup makes? My plugs look like lots more difference than what a 130 vs 122 would make, especially with my pods and pipes...
All LOOKS well on my bike - 125-135 PSI compression across all cylinders, just ran the valves, and only 1 exhaust a bit tight, but not real bad - and I fixed that with a proper shim.
Ah well, a set of 122's or 120's as a trial might be a start...

If so the numbering system is different.
Did you end up setting your fuel level in the float bowls with a piece of clear tubing, to just below the gasket surface?
Always a good Idea to check coil primary voltage and spark quality.
Then those Pod's are they clean, not oily? Only a light oil should be used, spray K&N Air Filter oil, or something similar. Over oiling can cause them to act as a Choke/ enricher.

??? not sure what you mean - I haven't yet even started to make any changes to my carbs, and wasn't REALLY sure but what the 130's WERE OEM - just doing research before I DO start - and I can't tell WHO might have made the 130's in there now, just jets with a "130" stamped on them...
Original pds were K&N, but dirty - so thinking that MIGHT make a difference, put on a new set I had bought, no difference, coils and spark look as normal as any I have ever seen...

Kawasaki.com shows main jet sizes over and below 117.5 (Part No. 92063-1107) as being for Race Use Only, which may indicate that 117.5 was the size as delivered new from KHI.
Good Fortune!

I couldn't tell you if the 130 is to big. But I would check through the usual to be certain before retuning the carbs. Check the fuel level, the coil primary voltage, spark quality, and the Air filters.
If all seems good, then adjust the carb mixture. Use new plugs and read them. There is a good write up in "Filebase" for Throttle Chop.

THANKS a bunch!
Those pointers gave me all the info I needed - I'll fiddle just a bit to see what I can do with what I have - looks like only the main jets have been changed, then if that doesn't give the results I want, the dynojet kit will be next!
