You’ll need to round up some basic tools before you start. It’s also a good idea to support the chassis with a jack, even though you don’t need to lift the wheel clear of the ground. Monster Valves and Mini Monsters can both be installed with the tires mounted to the wheel and under air pressure. As you drill and tap, the internal air pressure will blow the chips away and leave you with a clean threading surface. Flying chips mean you’ll need to wear safety glasses. You’re likely to lose all your air pressure during the installation, so make sure you’ve got an air source handy. The Powertank is ideal, but if you’d rather save your CO2 for the trail you can use shop air instead.
