CX500 Carburetor Maintenance.
​
The CX500 34mm Vacuum Carburetor System was specifically designed to operation on Leaded Fuel. With Current Exhaust Emissions now in force all Combustion Engines now run on Unleaded Fuel.
​
Unlike Leaded Fuel, Unleaded Fuel when evaporated leaves an oily residue on all surfaces. When Unleaded Fuel is left the CX500 Carburetor System for a lengthy period of time, the fuel slowly evaporates leaving an oily residue on all surfaces including the Small and Large Jets and also the Piloting Orifices .
​
This oily residue can have a Major Impact on the operating efficiency of the Carburetor System. The only alternative to clean the Carburetor system of oily residue from Unleaded Fuel is to completely overhaul the Carburetor System.
​
But to avoid this expensive and time consuming Maintenance, early intermittent Maintenance is the Key.
​
If the Motorcycle is to be left standing for long periods of time. Simply drain the fuel from the Carburetor Bowls, then disconnect the fuel line from the Fuel Petcock and gently blow air through the Fuel Lines to disperse any fuel left inside the Carburetor System.
​
This procedure can also be done on a weekly Basis, to ensure maximum Carburetor Performance if the Machine is left standing idle on Weekends.
​
But it is advisable to perform this procedure on a regular Basis to ensure maximum operating efficiency when using Unleaded Fuel in the Carburetor System.
