"cut the battery box off the airbox and make it 100 times easier to work on the carbs. https://faq.ninja250.org/wiki/Batter...r_carb_removal"
I've done similar to 1 of my Ducati's. The reward? Effortless, 10 minute carb removal.
Agreed, suggest to leave the (modded) airbox and factory spec jetting for a truly rider friendly 250.
Suggest to have carb "consumables" (orings and float valves) *on hand* before any removal. Bowl/pilot screw oring replacement is mandatory.
If present, drill the EPA caps on pilot screws to enable removal (with spring, washer and oring)
After emulsion tube removal, be especially careful to account for both small needle jets which frequently "disappear" (under the workbench).
After your chosen cleaning process (which hopefully includes aggressive compressed air), a wet test (pic) suggested to verify fuel levels and float valve integrity.
Followed with a bench synch. Reset the pilot screws (spring/washer with new orings) to 2 1/2 turns.
Also suggest opening the petcock, cleaning, verifying its clear as well.
Once idling, set each side pilot screw for highest RPM.
Thats all I've got for you, good luck with it.
