fuel cap and no key

[Anonymous]

Hello,I have a fuel cap on a rb tank and there are no keys. Has anybody dealed with this before and what to do?
Can imagine that it`s a matter of drilling,but maybe someone has a smart solution for me.
Cheers,

Had to do once for CB900. Used a pair of angle circlip pliers, to put turn pressure on the lock. Then using a needle file, put pressure on the lock blades. With the wear in the lock, as each blade lined up they would stay in place till lock released. Need patience and something to swear at, fiddly!! Good luck.

Hi Wim…………….

I have no idea, but was thinking. Is the fuel cap key the same as the ignition key ? If so can you see the number on the ignition barrel and get a key cut to fit. ? How about the tool box ? Is there a barrel number there ? Honda still do keys, I know because I tried to get a blank everywhere and they were only available from honda. I got a spare one for my RD ignition switch.
Again , I have not seen the underside of a CB fuel cap, but that may have a part number on it ( for the key ). My RD did not have a locking fuel cap. Guess you could remove yours and go for a non locking cap if it would fit. Consider draining tank and taking it off and taking the whole thing to a locksmith who should be able to open it easily. Then look for the lock number &/ or take a blank key and ask if they can cut you a new key. I’m fairly sure you can change the barrel part of the locks or perhaps one from a CB900 F may fit .
I am not sure I would want to drill the lock with a tank full of fuel vapour…………..just takes 1 spark and potential very loud bang .
I am sure you have thought of most of this , was just thinking aloud and think many options are worth exploring before butchering an original lock.

Regards,

Well I was very lucky with the cap, as Nat also mensioned in his reply I went to the key specialist overhere and with some dentists tool he managed to get it unlocked!! Was very glad with that so no heavy duty,must say that it is a dirty job to tap the 20 year old fuel out of the tank:(

Thanks for input about this.

Cheers,

Wim

Hi Wim

Is it a genuine Honda locking cap?

They are very hard to find in the UK but fitted standard to many German bikes. Due to the fuel breather being out of the side of the cap they can be used with a tank bag, so useful when travelling even if you don’t use the lock.

I have an after market locking cap which does the job but the quality is poor and I’ve had to fit 2 rubber seals to stop it leaking.

It’s good news you didn’t need to damage it.

Hi Trev,must say that I really don`t now if it`s aftermarket fuel cap. I thought that all original had the breather in the center on top of the cap!
But if I am correct there are also original honda fuelcaps with the lock on it?
Cheers,
Wim
