Your right on about the washers. I placed one end of the spring in my bench vise and bent it to start each washer. After all washers were in place I seated them with a small hammer. Make sure you install the washers so that they are on the bottom of the spring when in place. Use a pliers to remove each washer and you're golden.
Do a Google on Honda F6B and find the Power Sports sight. Look under accessories.
