Topic: 1978 CB750F Missing Fuel Door Lock Solution?

[eighty_HD]

I have a 1978 CB750F with a missing fuel door lock. Any suggestions, I am open to any and all. I am not worried about the door locking. Does anyone know of a low profile push button latch or something of that nature to plug the hole? Or would anyone happen to have an entire ignition/lock set with keys to replace all of mine with? I am trying to get away with not having to carry 2 keys for the bike. Any and all ideas or suggestions are greatly appreciated. Thanks in advance, and thanks for all the great info thus far -Luke

The fuel door doesn't actually lock, you just need something that fits in it to turn it to open.  ie a screwdriver, key, etc.  So you should be able to get another fuel door lock from another 750F and it should work just fine with your existing key.

Excellent! that makes life easier for sure! Thanks for the reply.


Anyone have an extra fuel door latch laying around?

Do any other years/models use the same latch? This will help broaden my search... Thanks guys!

I have a '76 750F, and had the same problem.  When I bought the bike, the lock was completely corroded (thank you Pacific Ocean), and I had to keep a shorty screwdriver in the trunk to open it.  b82ta is right, the lock isn't actually keyed.  I found a new door and lock on ebay for about $20.  The '75-76 doors/locks look to be the same as yours.

Thanks. The search is on!

Anybody got one?

The 550 F model tanks 75-77 used the same latch type, as did the 77-78 K model tanks.

Just to expand your search parameters.
