2-stroke Kawasaki KX, almost all size bikes use the same from 80 up to the old 500's and that is what fits GG. Do a search for "puller", I posted once with (I think) part numbers and thread sizes.
here, I'll save you the time....
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.
