short entertaining speech

Air filter is blocked so there's not enough air input. There is a problem with motorcycle sprocket, like idling air inlet congestion, then the air input just isn't enough. The oil amount of float chamber is too high, some gasoline go directly into the cylinder without atomization, that may cause incomplete combustion. Main orifice wearout seriously and then this fuel injection from primary nozzle increases, that may cause incomplete combustion. Heating automatic valve is at start position along with the enrich valve can't be closed automatically, that can caused a wealthy mixture. Carbon deposit in muffler, exhaust jam, waste gas stay in cylinder, that can caused incomplete combustion then black smoke. Diesel particulate filter, filters the particulate matter by forcing the exhaust gases to secure a ceramic wall flow filter. The ceramic wall flow filter has a porous wall and is single ended. When the spent gases are forcibly passed through the porous wall, the particulate matter is filtered as well as the gas is let loose thereby reducing the particulate emission in the atmosphere. 6. The use of smaller words and shorter sentences Air filter is blocked so there isn't enough air input. There is a downside to motorcycle sprocket, like idling air inlet congestion, then this air input isn't enough. The oil level of float chamber is simply too high, some gasoline go directly into the cylinder without atomization, which will cause incomplete combustion. Main orifice wearout seriously and then the fuel injection from primary nozzle increases, that can cause incomplete combustion.
