You mean transmission secondary belt pulley nut on a 1999 big twin? And your manual states counterclockwise for  loosening the nut?

Up till 2006
The transmission sprocket nut has left handed threads. Turn
the nut clockwise to remove from the main drive gear.

2007 on
The transmission sprocket nut has right handed threads. Turn
the nut counter clockwise to remove from the main drive gear.

I just drill them off. Two 1/4" holes, drilled through the face of the nut, at the flats, one wack with a chisel and it falls off. It is not worth the effort to save them!

I see some conflicting information here.  The OP says 1999 which then should be a left hand thread.  Turn a left hand thread clockwise to remove it.   :nix:

Is that an answer or a question?

On OEM Gearsets

Front sprocket nut

Five Speed=Left Hand Thread

Six Speed= Standard Thread

Clutch Hub Nut is Left Hand Thread on all.

OP: Don`t worry, even if you keep turning it in the wrong direction it will eventually come loose...

No matter how you remove it, you still need to confirm left or right hand thread to buy the replacement nut. I say back up, look at the threads that are  exposed, determine the direction and if left hand reverse your approach.  If it doesn't budge go to plan B with a drill in your hand.  At least the nut on route will be correct.   

By the info left by the OP it is a 5 speed and therefore a left hand thread. There is a small chance the transmission has been changed to a later model (if a 6 speed) that may be right hand thread.

Yup, my bad since I'm use to working on the 6 speeds.  I'll give it another try tonight.

No conflicting info in my post. Left handed thread you turn left to tighten and right to loosen
Right handed thread you turn right to tighten and left to loosen

Scotty Scotty Scotty.   :doh:   Read ALL of post #9, not just the part attributed to you.  The OP stated he was turning "counter clockwise per the manual" (left) and you gave the opposite (albeit correct) information to turn it (right) clockwise to remove it.  To me that is conflicting information.  I simply supported your statement.   :nix:   :scratch:
