I have a 93 CBR 600 F2 and my evap purge control valve broke and I don't want to order a new one so Im resorting to taking it all off. I just need to know what all I need to disconnect and what I need to plug.

 

There is a diagram on the top of the airbox that shows the evap layout. Basically you have to plug vacuum lines that lead back to the carbs so they don't lean out. The valve opens up to suck vapors that collect in the cannister under the bottom of the bike. At least on Calif bikes. You might find a valve on ebay or through a local salvage yard.
