G'day mate, welcome to the Org.
Please don't take this the wrong way but . . . .
aaaaahh, you are taking the p*ss, right?
Do you not know the Busas have a hydraulic clutch?
No cable to 'adjust', if there is too much freeplay at the lever, the clutch hydraulics need to be bled, first step.
If a good air bleed does not improve the excess play at the lever, then it's time to look further and deeper into the clutch actuation,
master cylinder worn?
hydraulic hose faulty?
slave cylinder faulty?
Pushrod damaged, bent etc?
Process of elimination step by step will sort the problem.
If you are a novice at mechanical work, take it to a reputable bike shop.
That's my best advice.
