Locking Fuel Cap Refusing To Lock.

Neale McConnell
Have you tried soaking the key with wd40 and leaving for a while. Other thing is to check its the same key to lock and the cap isn't one someone fitted and lost the key. But they are cheap enough to replace.

Yes mate let it soak. Then fill the keyhole and gently wiggle the key a few times repeating the keyhole and wd. Wish you luck.
Regards
Joe.

 

Count your blessings.
I had a series of Guzzi Californias.... all had the endearing habit of the key to the petrol cap key jamming in the lock when filling up with petrol.
You'd be surprised how difficult that made things....the key also worked the ignition...so I couldn't close the tank or start the bike.
Embarrassing.
