I have a 2007 yamaha virago (v-star) 250 that I've recently purchased. It is a small cruiser with a preload rear suspension. I am trying to change the rear suspension to its factory setting, but I can't figure out how to do this. I've tried twisting with screwdrivers and wrenches for leverage, but I keep stripping the metal. I'm wondering if I'm doing this wrong,please help!
Here's a picture (not mine) of what I'm looking at.
Again, I am completely mechanically incompetent, thank you for your patience.
