On my Xingyue 150ZK Auto Moto trike the emissions canister top hose comes from the air box- the bottom smaller hose goes to the differential,another hose goes from the canister back to the air box and gases are re introduced into the carb and burned. The canister is crucial to allowing all these China scooters into the USA. Last year Auto Moto went oob because of failed muffler emissions by customs. Their entire shipment of trikes were sent back to China
