I have a 93 K75S that is misfiring when cold,once I coax it over 3th revs it runs better. Have checked the fuel & air filters ( cleaned out the mouse nest in airbox ) but still runs poorly  when cold . Any suggestions on what to check would be appreciated. JD

Make sure all the electrical connections on the ignition are good, pull the plug caps and check the little bobbins are on the top of the plugs and that the leads are connecting, white powdery stuff is a give away to a bad connection on the high voltage side. Even replace the plugs.
