FreeWay Posted October 18, 2009 Share Posted October 18, 2009 This is my first forum posting. Just bought a 1973 DT3. The gas cap gasket is really bad. They don't seen to be available from Yamaha. Anyone have a source for these or is there another fix? Link to comment Share on other sites More sharing options...

Anyone have a source for these or is there another fix? Hello one idea to replace your 'gas cap gasket' that I would try would be to try a vintage vehicle component supplier, take measurements of the gasket, you will need the inner / outer diameter & gasket thickness, if no joy there,with the measurements, you can go to the web and search for standard gasket sizes, There exists industry standard sizes that will allow a gasket supplier to provide the required gasket in the correct size, in 'O' ring type gaskets I think they are called 568 dash codes. you will have to select a material that will be impervious to unleaded fuels. Most likely you will need a gasket made from Fluoroelastomer or Nitrile butadiene or if you feel rich Perfluoroelastomers, alternatively you could get a sheet of the correct elastomer at the correct thickness and cut out the required shape, Hope this helps Link to comment Share on other sites More sharing options...
