let me rephrase, 14 years ago it was upjetted and the full exhuast was installed. it was running great for a while and then the owner went down, and the bike sat for 14 years..
sorry for the confusion
i pulled the bowls off, floats out, ensured fuel from the rail was getting into the bowls, cleaned all the jets in my ultrasonic and compressed air. they look new, i can see through them completely and perfectly. bowls, floats, float needles, all jets were all cleaned.
i pulled the slides out, the needle jets, and the springs/diaphragms.
carb cleaner was used for the majority but i run a diluted simple green / water mix in my ultrasonic.
tank was surprisingly clean and almost empty! i removed the petcock and took it completely apart, it was pretty grimy
since it's vac, after a fuel flush with the petcock back on, i could confirm the vacuum was working to put gas into the (new) fuel line from the petcock to the carb fuel rail
