Choke help
My buddy has a 98 cbr f3..when the choke lever is pushed up..the fins in the carb are almost completely closed..when the choke lever is pulled down..the fins do not move...the cable is attached to slider and I can see it move a little but it doesn't seem to be sliding enough to open the choke fins. ..any suggestions on what might be causing this?

Not exactly sure what you mean by the fins. Are you speaking of the butterfly valve that is in the throat of each carb? If so, they aren't affected by the choke lever.
There are four arms on the slider. Each of these arms should be connected to the head of a needle valve. When you push the choke lever up, the slider should move the needle valves about a 1/4th of an inch or so. If that isn't happening, check the clamp on the side of the carb rail that holds the cable in place. If it isn't tight, the whole choke cable will move when you manipulate the lever, not just the inner cable.

Sounds like they are stuck. Look at #12 on the following link:

The needle valves have a spring around them. They should stay closed unless opened by the slider. If you are doing it manually, they should snap closed pretty quickly.
Yes, you should be able to manually push the slider. If the bike sat through the winter without starting and had fuel in it, everything is probably gummed up.
