Carburetor schematic Yamaha Ext1100u/v/w 1996-1998

Spring washers on carburettor assemblies play an important role in not allowing items to unscrew themselves. Using the correct genuine Yamaha spring washer will help everything stay put, and the carburettor to stay in tune

Mixing nuts and bolts from different manufacturers can lead to real problems of threads not quite matching up, and also when the part is visible can look at odds with the rest of the machine. The carburettor is a delicate piece of equipment and using only genuine Yamaha nuts will save the potential for cross-threaded disaster!
