When using a breaker bar, securing the sprocket right by the nut through the drive chain with the rear wheel properly blocked in the swingarm (rear brake as recommended in repair manual is not strong enough), isolates tranny from any stress. An impact wrench delivers very high peak torque successive hammering impacts to tranny and engine components... If you must use it, leave tranny in neutral, have someone firmly apply rear brake, preload the socket counterclockwise to take up chain slack and let it bang away... Countershaft sprocket nut still has to be torqued back on properly with a torque wrench by blocking the rear wheel.
