Usually, it's pretty obvious it an enrichment device (choke) on a single cylinder engine is working or not. The engine runs and sounds differently with it engaged and disengaged.
If I wanted to verify operation, I'd carefully disconnect the nipple that attaches the enrichment feature and make sure that the spring loaded slug was retracting and advancing when I worked the lever on the handlebar. It's spring loaded and the spring needs to overcome any friction in the sheathed cable that connects it to the lever. The cable should be lubricated periodically anyway, so I'd certainly do that while I had it disconnected.
The enrichment feature is shown disassembled in this picture and is directly above part #9

This is actually a larger BSR type in the image, our GZs have Mikuni BSR32 installed by the factory.
