40 NEDW#3/2 175/172 main. Should have it zippin around no worries. Seeing as you have the 40 and 175 in there already I'd just start with clip 2 for a test ride. Move to clip 2 if it feels too rich. Then after your weekend decide if you want to drop the main.
Not sure on the root diameter of the CCK but if the bike idles high when you put the NEDW in don't freak out immediately thinking its lean. Simply try to back the idle down to a good level.
