ratchet? clutch? tabs?
somebody take one apart......the thing I'm pointing at is a roll pin....
I guess one could refer to a couple of toothed roll pins as tabs, but ratchet or clutch are both kind of a stretch.The stove knob WILL jump the tabs if you turn the key with enough force. Try it with some pliers . It's to prevent damage to the ignition if somebody wants to try to steal the bike. Actually a clever design. Don't confuse how something works with how to take it apart .

I'll thank you in advance for your apologies...
D'OH!
I knew I jumped in too quickly!
I apologize. You're welcome, you earned it.
I actually take mine out once a year to clean underneath the rim ( easy folks, talkin' 'bout the stove knob on the bike) but I haven't
twisted it hard enough yet to get it to ratchet or what ever it's doing for the rest of you.
I can't argue that what you're pointing at is a roll pin, that's pretty obvious. In fact there are TWO roll pins, one on each side and they do NOT meet in the middle.
But there is a clutch/release/ratchet mechanism inside the stove knob. They are actually quite difficult to disassemble but it's really easy to demonstrate the release/re-catch by clamping the key in a vice and turning it. Note the video and I'll thank you in advance for your apologies...

I apologise, sorry for not explaining further, but I do thank you for the video.
I never tried to force the key, was not willing to damage it prematurely on my part.
I will explain tho, the year I bought my bike, and had the rear brake lever warranty failure, I was talking with the service tech in the showroom, and he asked me about a knob failure.... someone sat on a bike and twisted the knob, reallly hard, and it failed internally, and they couldn't remove it.... I did spin it a coulple times, smacked it with a rubber covered screwdriver handle, and it still spun freely, absolutly no resistance. All I could suggest to him was to try to compress those roll pins in with a C clamp, and see if it had any effect, and if not to jamb a small nail in thru the center of the pin to see if he could get it to wedge up enough the function it.... they were pretty bummed at the time, because they had a buyer for the bike, but couldn't finish the prep....
ouch.
I had to leave and never followed up with them about what broke, This was wayyy back in time, and I posted that picture and asked if anyone had disassembled one yet, I guess nobody has, id like to see the insides, but won't risk damaging one to find out.
after watching your video, I'm figuring there is simply a spring loaded disc inside, with 2 grooves, that cradle the roll pins, seems simple enough, and would offer that resistance seen.
I figure the one I saw had that disk fracture/split, or the spring popped, or both, as the knob spun free, you could push it with one finger.
thnks again, and sorry for the miguidance on my part.
The video was helpful in understanding the "clutch" arrangement.
Just for the sake of clarity and as the OP of this thread, I am not in the habit of forcing any mechanical structure to do anything that it isn't supposed to do.
As I said upthread, I did what I always do -- get on the bike, press downward on the knob, and turn the key to the expected location/detent. No muscling involved, no getting pissed off and flailing around. Put simply, the key did not detent where it should have. I did try that process several times with the same result, meaning none. Either the clutch didn't disengage when it was supposed to or somesuch - I don't know.
The video shows a fair amount of effort being made with the key in the vice. No way did I use that kind of effort to turn the key in the KI-PASS lock.
Eventually it came around, but it wasn't looking good there for a few minutes.
I'm still of the opinion that someone messed with it while you were away. They tried to either start the bike or take the key and failing that, left it between detents which is how you found it. I'm sure the actual resistance of the mechanism varies. It wasn't as hard as you might think and I only clamped it in the vice for ease of demonstration. It will do it in the ignition of the bike and would also easily do it if you grabbed the key with pliers. But my fingers are not strong enough to hold it. I note that the force to overcome the detent is quite a bit larger than that needed to turn the C14 ignition switch.
But anyway, I am sure this is designed this way to prevent some bonehead from twisting the key off either accidentally or intentionally.
