Modern fuel, with bio methanol plus other corrosive elements can play havoc with an older fuel system designed to use older, purer petroleum.
Failure to drain the carburettor for the winter lay up allows the fuel to turn into varnish, blocking the jets and coating the float and float chamber, sometimes to the point where it becomes so difficult to clear, replacement of the affected parts may give preferable results?
If you are overhauling your carbs, or just carrying out a light service, then this component and perhaps some of those listed below maybe required:

Add as many components as you wish to the same shopping cart, new screws 1AE1456500 1FN1456500 9850105010 & float pins 3531418600 for example, and still only pay the same single fixed price shipping cost. Engine work to carry out? Pro-workshop gasket sealant 08C70K0234M - easy to apply with excellent results. This component may have other, sometimes unrelated applications within the Yamaha model range, so please always check by the part-number rather than the description prior to ordering.
