Factory Pro makes a kit that comes with a pilot jet, main and needle.
they also make a nice thumb screw for the VLX mixture screw replacement.
otherwise it requires a D shaped tool to turn the screw.
like he ^^ stated the Cobra kit is a rebranded DJ kit.
DJ does make a good kit, but it does not come with a pilot jet, you will have to get that at a dealer or Jetsrus.com
