Getting your flywheel/rotor off would probably be easier if the bike was still mostly in 1 piece. Put bike in 4th/5th gear, rear wheel on the ground, remove the cover, remove the bolt that holds the rotor to the crank (see previous statement-a 1/2" socket set would probably work best), screw the puller into the bolt hole and take a wrench to the puller. Keep tightening. You want to screw the puller into the rotor until the rotor pops off. I do believe it's just like tightening any bolt. I did mine recently with the engine out but I had an advantage - AIR GUN. Came out real easy.
