This isn't much but I hope it helps someone, I know I spent considerable time researching it. Flywheel puller for GG 2T (works on both my bikes) is
"Magneto/Flywheel/Rotor Puller. 27mm x 1.0mm fine left hand threads. Kawasaki flywheel puller. Most off road and MX and Enduro models. 2 cycle 80 MX to late 500 MX models and KDX Enduros." This from Ricky Stator website. I bought a K & N brand puller (air filter folks) from the local Kawasaki dealer for $30 and it works perfect, part #82-0150.
