Clutch fluid? Leaking around the 'clutch lever'?
I'm going to make a wild guess here...
You never bought a service manual for your bike did you?
Not being an ***, but hard to tell what you are trying to describe as where the leak is...
The 'clutch fluid' is actually primary fluid. The level should be at the bottom of the clutch spring retainer plate, which can be seen by removing the derby cover. The ring on the clutch pack with 6 hex head bolts in it is the clutch spring retainer plate. The oil should come to the lower edge of this plate. I believe the manual calls for 32oz on the '07. Earlier models were like 28oz.
(EDIT: The levels I indicated here are actually for the transmission. The primary capacity is 32oz, if I'm not mistaken.)
There is no 'clutch lever' connected to the primary cover. If you are saying the oil was forced up the clutch cable and leaked out on your hand at the clutch lever on the handlebar, then I'm kinda at a loss here. The primary fluid could theoretically flow through the main shaft in the transmission, and then overfill the transmission through the trap door cavity. But the transmission is vented through a hose behind the primary inner housing, on the transmission case. For it to flow up the clutch cable all the way to the handlebar lever, I would think that transmission vent may be plugged.
Get a turkey baster from the kitchen and suck out what needs to be removed from the transmission filler neck. (you might need to connect a hose to the end of the turkey baster). Check level with the transmission dip stick. For the primary, pull the derby cover off again, and check the level at bottom of the clutch spring retainer plate. Clean excess oil off of clutch cable, and see if that helps.
