HOW TO install a fuel screw on a DRZ400.

This is a how to video on how to install a fuel screw on a DRZ400. If your carburetor has not had any adjustments then you'll likely need to remove the brass plug that is covering the stock fuel screw. To do that, you drill a small hole into the plug (don't go too deep!) and then thread a screw into it so it will push the plug out. There are directions online on how to do that. If you don't know what you're doing, DO NOT CHANGE ANYTHING ON YOUR CARB. My bike has a JD Jet kit already installed with the proper jetting so I know what the fuel screw needs adjusted to.
