If the engine is not running as it should, hesitant throttle pickup, loss of power or poor starting, have you thought about a complete carburettor overhaul?
The part shown in the image is just one item of a few you may require to return the engine back to full power and easier starting.
Other items you may wish to consider:
Add as many items as you wish to the same shopping cart, new float valve 160301057 valve clip 16044007 & shiny new hose clips 92037139692037147 for example, and still only pay the same single fixed price shipping cost.
This component may have other applications within the Kawasaki model range, so please check the part-numbers you order are correct for your model.
