Check your service manual, all specs are in there

 

Dunno about a service manual, but the parts fiche has that.

27 Jet, Main #107 4H7-14925-07-00
29 Jet, Pilot #36.5 (#36.5) 4H7-14948-36-00

 

From my service manual, 85 xj700n. When cleaning carbs be sure not to reverse the air jets

Main Jet # 107
Main Air Jet #70
Pilot Jet #70
Pilot Air Jet # 210

 

And just in case it's a XJ700-X (water cooled model):

MIKUNI MAIN FUEL JETS:

NOTE: stock Mikuni XJ series carbs used the following original main fuel jet sizes:

#100 is used on:
1985 all XJ700-X models (*see note below)

NOTES:
* there are discrepancies between the parts manuals and the service manual information on the size of the 1985 XJ700-X main fuel jets; one source claims these carbs were equipped with #100 main fuel jets, while other sources claim a #105 size main fuel jet. Our experience leads us to believe that the correct size for the XJ700-X and XJ750-X models is the #105 size for both the 1985 and 1986 model years.


MIKUNI MAIN AIR JETS:

Alas, the Mikuni BSxx series carbs used on XJ models---unlike their cousins the Hitachi HSCxx series carbs---did not have replaceable main air jets. The main air jets on these models are in the carb throat, facing the airbox, and are a small, brass pressed-in tube that is non-replaceable, and which we suggest you do NOT try to modify by drilling or enlarging.

And just in case anyone is wondering, here are the sizes of these non-removable main air jets in the various models:

#120: XJ700-X all models and XJ750-X all models



MIKUNI PILOT FUEL JETS:

ef) OEM and aftermarket Mikuni brass PILOT FUEL JETS, sizes as follows, fits all XJ550, XJ650 Turbo, all XJ700-X and XJ750-X, all XJ900RK, RL, N/FN, and F models, and XJ1100 models.

NOTE: stock Mikuni XJ series carbs used the following original pilot fuel jet sizes:

#35 XJ550 all 1981-83 models (except Euro), 1984-85 FJ600, XJ650LJ Turbo (1982), and XJ700-X* all models

NOTES:
* there are discrepancies between the parts manuals and the service manual information on the size of the XJ700-X pilot fuel jets; one source claims these carbs were equipped with #35 pilot fuel jets, while other sources claim a #37.5 size pilot fuel jet. Our research and experience shows that the XJ700-X models always used the #35 pilot fuel jets, while the XJ750-X models used #37.5 pilot fuel jets.



MIKUNI PILOT AIR JETS:

Pilot air jets on the Mikuni BSxx series carbs are replaceable and are located under the diaphram cover on all XJ550 models and XJ650 Turbo models, and in the carb throat (facing the airbox) on all XJ700-X, XJ750-X, all XJ900RK, RL, N/FN, and F models, and XJ1100 models.

ef) OEM and aftermarket Mikuni brass PILOT AIR JETS, sizes as follows, fits all XJ550, XJ650 (except Turbo), all XJ700-X and XJ750-X, XJ900RK, and XJ1100 models.

NOTE: stock Mikuni XJ series carbs used the following original pilot air jet sizes:

#140 XJ700-X and XJ750-X models



MIKUNI BOWL STARTER JETS:

#35 XJ700-X and XJ750-X models*

* Non-replacable, non-removable, very likely clogged.
