R&D Flex-Jet on '99YZ400F Carb?

I just completed a rebuild of the carberator and added a JD Jet Kit and R&D Flex fuel screw.

I put everything together and the bike started right away.:excuseme:

I was very happy about that.

The problem I am having is the suggested mounting position for the end of the Flex fuel screw does not work with the bike.

Has anybody else had this problem, and what solution did you come up with?
