Tamper proof oil filler cap

Hi all Is there one of these available for the CB1100? If not does anyone know if the BMW one would fit the Honda? (most likely different thread/hole size)

Good question, and nice find MC.

The tamper-resistant filler cap is also good lookin'.

They look nice. They are just a torx though- tamper ones would have a nub in the center.

I'd suggest silver as the anodizing would mar where the tool rubs.
 
I was wondering the same thing tommymck
 
If someone has a BMW that these fit, it would be easy enough to see if they fit the CB1100 before you order any.
 
If I recall, the BMW has a larger diameter hole than we do. My old R1200R had a factory tamper-proof oil cap. It had a funky triangular shape to it, which required a supplied tool to open.
 
My 2004 BMW R1150RT has a completely different cap. It is all plastic, but is not threaded at all. Inside is a plastic T which fits into a slot inside the case. Nothing threads into anything.
 
How about tamper-proof valve stems? Or tamper-proof throttle cables? Or spark plug caps? Axle bolts? Rubber hoses? Bleeder screws? There are too many exposed components on a motorbike to worry about that could be tampered with that would leave you stranded, or dead.
Sobering thought.
 
When I was in the Army- I got a knock on my door one day- and a guy told me he just saw somebody sitting on my bike and it fell over and they left... oil cap wouldn't fix that either.

I've actually seen a 'mom' put a small kid on someone's bike in a parking lot as if it was a ride / toy. I was livid inside.
 
Most tampering happens without a plan. So what can happen to a bike without a secured oil-filler cap ?
- the cap is stolen, not a disaster so, just plug the hole and ride home
- the cap is opened and sth filled in - but what ? water, tooth paste, gas ? If that happens you're either very unlucky, or it's done by the neighbor who you know and who hates you ...

Anyway, an tamper-proof cap would have to have more than a torx head, torx is too common these days.

I saw a 'mom' let her 5-year old bang his toys on the wings of an airplane parked during an airshow - imagine the fury of that owner (a flap bent and you can't fly home no more).
 
Not too long ago, I saw a couple and their little daughter with a '48 Packard at a show. The girl was pretending to drive the car, tugging at the wheel and playing with the dash switches while the parents took pictures.

I commented "Wow, you sure have a beautiful Packard."
They replied "Oh, it's not ours..."

I reckon a tamper resistant oil cap is for those who might need to leave their poor ol' CB parked in the dubious part of town overnight and wish to minimize the opportunity of some punks pouring sand and gravel into the crankcase.

Conceptually very easy to do with maximum impact.

My Bolt requires removal of covers to access the spark plugs

The only tampering I've had since 1963 was theft of a battery out of my 1970 CL350 at an apartment in 1971. No wires cut, just bought a new battery.

Thereafter all bikes were garaged, but sometimes parked at a hotel or cabin overnight.

As for tamper-proof (resistant) items, just don't lose the tool!

Ive had that happen to me. My old CB750, guy that worked in building behind me put his kid on my bike, saw it happen, went out and just sat on the hood of his car. (i was 25? or so at the time). I thought he was going to lose his mind. Yes, harsh words were exchanged.

He never did it again.

Last year a caught a dope using my gas tank as a coffee table as he took drags on his cigarette. In short, after I confronted the behaviour, the rest of his day was bad.

Sadly, it didn't have to end that way. He could have just taken the coffee off my bike and acknowledge the unacceptable behaviour. Instead, I got attitude and he felt that I was "commanding him". I assured him that he was correct on that.
 
I like those toughening, heart-warming John Wayne sort of stories, but the truth is too, most of us CB riders are in their 60's and 70's (that's why we like the bike), and it may be less and less wise to confront the young wrong-doers in an aggressive way. Repairs on the bike tend to be cheaper than "repairs" in hospital.
