Engine Air Pump with Adaptors
This is the most efficient way to fully re-inflate a motorcycle tire when an air compressor is not available. It converts any 2 or 4 stroke engine into an air compressor. This pump uses the vacuum of your motor to suck clean outside air into the hose and the compression to force that air into the tire. A two-way check valve prevents any gas fumes from entering your tire. The five foot hose easily reaches the front and rear tire valves.
The Adapters come in 18mm, 14mm, 12mm, & 10mm sizes which covers the vast majority of cylinder heads made today. However, the spark plug opening on late model BMW's is too narrow to accommodate this unit. As long as you carry a spark plug wrench and can access your plugs easily, this pump will provide you with a lifetime of unlimited clean outside air.
