Um, well the plug chop will tell you only Mainjet & has to be performed properly or is useless.
My 91 worked just peachy on site recommended jets. Some variation can be expected using different gas & oil mix ratio + from bike to bike etc.
I’d also check for airleaks esp in airbox manifold, filter, reed manifold, crank-seals etc just to be sure, then if you feel you need richer then go richer.
PS: for the less than full open jets make sure the slide isn’t grooved or it will leak, causing a lean condition, had to replace mine & yours is probably as bad.
Ah I see you've posted more than one thread, best not to do this.
