Pulling rotor off Kawasaki KZ250

I need to inspect the starter chain as it appears the starter does not engage the flywheel consistently and makes lot of spinning noise. I have the left side cover off, but do not have anything to pull the rotor off. What tools do I need to pull the rotor off so I can inspect the chain?

Not sure about the 250, but usually you need a flywheel puller which is basically a reverse threaded bolt that pushes the flywheel off.

Thanks...think I saw one at Amazon
