Float Bowl Gasket
Modern fuel contains Ethanol which reacts adversely to many rubber compounds, Kawasaki OE, and Tourmax float bowl gaskets are particularly vulnerable to this.

Nitrile gaskets are considerably more resistant to ethanol but should they swell and become oversize leave them for 24 hours and they will return to their correct size.

Alternatively consider using our Nitrile Gaskets which are made in the UK to our specification - these are considerably less susceptible to swelling.
