Fuel tank lock

I'm reviving an 81 3X0

1981 XS1100H 3X0 New Yamaha Black Europe

This would be a bike with the recessed cap presumably. BTW, I tried to open mine without a key and after a half an hour, no luck. Best bet is to have a key made as suggested.

Yep, it has the recessed cap. i've read some nice tips , thanks for those. I will try them all tomorrow evening.

Hi guys,

I'm reviving an 81 3X0 for a friend of mine. I installed an ignition lock with key I had lying around but the key does not fit the fuel tank lock. Anyone has an idea how to open it without destroying the lock? I know that, with the lock disassembled, I can get the ignition key to work with the existing fuel tank lock.
Only question is how to open the fuel tank lid without destroying the lock....
Because this information cannot normally be published on a forum (I know why., don't know what the mod thinks) I would appreciate it when you send me a personal message.

thanks!

Hi Math,
what's a 3XO?
If it's a Special it's the same cap as an XS650.
They can be popped open by shoving a medium sized screwdriver straight in horizontally under the cap from the front.
This moves the latch back to release the cap.
If it's a Standard flush mount fuel cap, you are SOL unless you can pick locks.
