When the motorcycle is kept in the garage or indoors, there will be a heavy smell of petrol. This is not only unhealthy and a waste of petrol, but also a safety hazard.

The two-way valve is a unique device inside the fuel tank cap to avoid risks incurred by a choked carbon canister which may be caused by mud, dust, or other particles.

When the temperature inside the fuel tank is too high which leads to a higher pressure than outside, the two-way valve automatically opens to outlet, preventing the fuel tank from cracking and avoiding fuel leaks. When the air pressure inside the fuel tank is lower than outside, the two-way valve automatically opens to inlet, which facilitates the engine oil inflow.
