JD will give you a good starting point to work from, but it's not the final say. After using the JD instructions, I later changed the pilot and leak jet based on what some people were running and the bike runs (and starts) worlds better than it did after installing the kit originally.
Spend a few minutes reading through the jetting database thread and see which settings other people are using. Then spend about $25 for a needle and jets.
