I wouldnt mess with it if you dont know what your doing from what I understand it very easy to make a mistake and end up with a 800 lb paperweight. their is plenty of people out there that will do it for you on line for a fee. there is a lot of factors to consider on what you want out of your bike. I went to granstand design and bought a download for a hundred bucks a guy even talked me thru it over the phone and I like the way my bike runs. To the money was worth not having to deal with worring.
