Warranty Information

Please note that these diaphragms are not resistant against fuel mixtures containing Ethanol (E10, E15) and will slowly wear if left exposed to this mixture over time. These diaphragms and most CV carburetor seals have NO resistance to E85 fuel and E85 should never be used in your Harley or Keihin carburetor. Any fuel with or without additives should never be left in a Harley carburetor unused for more than 30 days. Due to the unknown nature of fuel additives used by the consumer or pump gas purchased, the manufacturer (CyclePro) does not warranty this product after installation.

    ordered and just exact fit and a+ with the screw's!

  3. Worked great, screws are metric

    Posted by on

    This diaphragm worked great and was nice that it comes with replacement stainless steel socket screws w/lock washers. The diaphragm from Harley is priced the same but doesn't include any hardware. Only thing that threw me off was the screws use a metric allen key.

    [Note from CVP: All parts on the Harley carburetor and many other components are metric, so it is recommended to have a few essential metric tools. These screws use a 3mm hex key. If buying our Tuners Kit or hardware kit we include a hex key to fit the new bowl screws.]
