You can make the parts necessary fairly easily.
Lowering the front, you can make spacers to let the forks slide up. I believe (Correct me if im wrong) that anything more than 1"-1'1/4" will begin to cause throttle/electrical cable issues. So if you want to go lower than that, it would probably be better to buy a triple tree.
As far as the back is concerned, take the stock links off and measure the length, measure from the center of each bolt hole etc... In order to make the links, you will actually make them longer than the stock links(Shorter links raise the bike). So you will need to measure and make the new links 2" or whatever you decide to go with, longer than the stock links. You can even make 1" increment adjustments by drilling multiple holes for multiple adjustments, or use aircraft rod ends, to make them adjustable with a wrench, similar to Soupy's Links.
Lastly, obviously the links are not something you want breaking at high speeds. They need to be made out of Billet, Steel etc.. or something equally strong that can take the stress. I would not go with cheaper aluminum just to save some weight, make them out of some quality metal.
