My guess would be 40mm female. I tried a 38 and a 42, 38 is too small and 42 is too large. I had a difficult time finding anything in between. I finally found a 40mm on eBay (surched the Dennis Stubblefield catalog and came up epmpy). I hope this works as I am struggling with the same problem you are, no one wants to list the VZ800 on their rotor puller sizes. My 40mm should be in in a couple of days and I pray it works this has been sooooooooo frustrating.
I got my 40mm puller in. the female threads fit my 2001 Suzuki Marauder, but the bolt (which is reverse thread) was too short to pull the rotor. I stuck a small socket into the opening in the center of the rotor and screwed the bolt in on top of that and was able to pull the flywheel. Now maybe I can finally get my bike back on the road.
You can use a three bolt steering wheel type puller if it is not too tight . You may need to purchase the puller made specifically for removing the flywheel that threads into the hub itself. I bought one on-line for $42 bucks. Absolutely DO NOT heat or hammer on the flywheel because you WILL screw up the stator , the trigger sleeve or the flywheel stator magnets that are epoxied to the flywheel. My flywheel was so tight, I had to put tension on the puller and let Liquid Wrench soak in overnight before it finally came loose. Note: Once your flywheel is off, DO NOT remove the magnetic sleeve pressed onto the inner hub. It is a critical timing piece that is epoxied onto the hub in a precise position that even the factory could not tell me how to position it correctly.
