They're actually not too bad to work on, and the stock oil they come with is way too thin. Someone suggested 50 weight, which sounded too heavy but worked out well with the stock tires. A piece of fuel tubing under the piston works good for lowering the ride height, or do what I did on my race pede and use a dremel tool to cut the springs. Just be sure to cut them all the same amount. Don't be afraid to experiment and find a setup that suits your needs and driving style. Keep in mind there is no "one" ultimate setup, it depends on how you want it to perform.
