Does anyone have any suggestions on pressing in the bushings on a Kawasaki 680V? Any tips and tricks? First set cracked trying to get them in. I lubed them. Was told my a Kawasaki mechanic to freeze them. Has anyone heard of this or have any other tricks before I get the new set in the mail. They are over-nighted and will be here Wednesday morning. Also does anyone have an experience with how much machine shops charge to press these things in?
