    Default How to make gas cap easier to lock?

    I have a 2015 F3 SM6, I am having a hard time getting the gas cap to lock and get my key out without breaking the key. It takes a lot of downward pressure to get the key to turn while pushing down on the minimal area around the cap. Do any of you have a remedy for this? I prefer to keep the locking cap.

    Kind Regards and safe Riding Willie……

    F3 gas cap closing
    by Rattlebars:
    1. Like the starting procedure, the gas cap closing has a specific sequence. After fueling, flop the cap back down into the hole. Turn the key clockwise to 3 o'clock until the cap drops almost all the way down. Turn the key anti-clockwise as far as it will go to 1 o'clock . Press down on the edges until it clicks. Turn the key anti-clockwise the rest of the way to noon then pull it out. Ready to roll.
    . I use this method and find it works well after I filed the lock tabs on the cap.

    Additional ideas:
    2. A bit of oil in the mechanism and Vaseline on the rubber also made a difference.

    3. I took the locking lid apart and filed the sliding contact parts to reduce the locking tab thickness.

    4. There was also a post that recommended making shim washers from the metal in a pop can. The washers are placed under the bolts that hold the gas cap lid in place.

    Good Luck..

    I did all of this and just got tired of it all... You can always replace the cap assembly with the one from Lamont and be done with it!

    This is a reply to a several month old thread. However, I know a number of people continue to have problems with latching the fuel cap. I had that problem again today and I also learned that the fix is easy and quick. It turns out that the rubber sealing gasket rides on a spring loaded guide and the mechanism gets sticky making the latching difficult or impossible. The simple fix is to lubricate the slide with a good multipurpose oil. A few drops above and below the gasket and then working it up and down until it moves freely will make latching the cap a one finger operation. I plan on carrying a bit of oil with me from now on in case things get sticky again.

    Taking the key out before closing the cap locks the latch mechanism on my 2017 F3.

    You will be unable to close the cap.
