My experience as a professional mechanic tells me that pulling a device such as a YZF flywheel with a 3 jaw puller is very ill advised. Pulling it this way puts a lot of strain on the face of the flywheel in a way that the engineers did not intend for it to be applied. The center will flex into a dished condition, which reduces the force actually trying to break the taper free, and can permanently distort the flywheel. You can say that you've done it, and it worked for you, but I can tell you that you got lucky. I've replaced a number of them that were pulled, or tried to be pulled that way. Grey man, you're gonna give me a complex if you keep trashing my cowboy ways. And I thought I was doing so well when I started using the puller instead of prying it off with 2 tire irons. J/K, I've been in the North so long that I forget what the real world is like. Our motto here is: "We the weary, working for the unknown, doing the impossible for the ungrateful, have been doing so much for so long with so little, that we are now capable of doing anything with nothing at all." I guess I should include a disclaimer with future technical advice - I live and ride a thousand miles from nowhere so I do whatever it takes with whatever I can find.
