Starting fluid is not a path to a repair, on the contrary can do permanent damage to the costly slide rubbers. Its use will not correct the root of the problem.

The pilot jets are drilled so large that you, being "new to this stuff" can tell?
Not sure what would motivate someone to create that destruction.

Yes, a return to new, correct pilot jets would be highly recommended.
Keihin size 38 pilot is what the factory supplied. That would be the first, obvious recommendation. I believe I've got them in stock.

Its dawning on me, if pilots have been radically drilled...what other "tricks" did a previous owner do to the carbs? A scary thought.

Are the main jets marked with a size? Tiny, stamped on the side of the jet.
Needles have numbers? Are they adjustable (with a clip?) indicating a jet kit is installed.

Beyond replacing pilot jets, there may be more involved.

Your carburetors need careful review in and out, top to bottom......now knowing that someone irresponsibly hacked the pilots...WHAT ELSE DID THEY DO? OR NOT DO?

Does the bike have factory airbox and exhaust installed?

I dunno...you may want to consider my services. It would certainly cut to the chase.
