See my "black plug, black smoke" thread. I lubed my choke lever last night quite successfully.

I should have taken pictures, but here's the steps:
- dissassemble the switch housing (houses the horn, signals, and light switches) on the left handlebar:

There's three screws on the bottom of the housing. Take out the two black ones. Carefully take the housing apart (splits into two sections.) Pull out the choke lever, slip out the cable, and set the lever to the side. You'll probably have to loosen the friction rings to do this.

- unhook choke lever at carburetor:

I found it easier to take the tank off (it takes 2 minutes at the most,) but you don't have to. Simply unscrew the nut (14 mm wrench) and slide out the choke cable. Don't lose the spring or the connection thingy (don't know the name, haha.)

- from here you'll know if it was crimped at the carb end (needle not sitting correctly) or just siezed.

- If siezed, you can lube it using whatever kind of lube. I used WD40 and applied it using a cable luber. Because it's not a normal cable, the cable luber doesn't seal too well around the cable end. In addition to the luber, I used a rag to seal it at the luber and at the friction rings and had a helper spray the WD40 into the luber. Using the rag prevents the lube from flying all over the place. Keep pumping lube until it comes out the other end and stop. It doesn't take much.

After that, my choke lever is easy to move, but still stiff enough.
