How many keys and coolant cap

[Quince]

The seller of my bike gave me two sets of two keys, one for ignition and seat unlock and one for the leather saddlebags. While flushing rear brake fluid and getting new coolant I saw under ignition what looks like a helmet lock, just like on my ZZR1200, but none of my keys fit the lock. Is this a standard feature on 1500C and I didn't get a key for it or an add-on optional item. If this is a standard feature, does anybody know how and were to get a key or two for it? Kawasaki used to have records of all the keys for each bike but I do not remember if dealer made a copy for me from the old one or they just order one.
On a different topic, after I couldn't take out the radiator cap, I noticed a small screw on the side lip of the cap that was locking it in. Now I am wondering, since this looks like a bandage to some issue, what could that potential issue be to physically lock the cap with a screw on the side?

One key for ignition,  seat and steering head on my standard.   One of the standards had a cable lock that protruded from under the seat that utilized the seat lock to secure a helmet.   The screw in the cap I believe to be a safety measure to secure the cap from coming off while in transit.

You can probably get key blanks at a hardware store, if they make keys, and have them cut to match. Or, you could find Ilco HD57 blanks on line, and have them cut; that's how I got my spares.

Is the radiator cap chrome? Many such are just chrome covers attached to a standard cap with a screw.

My issue is not making a double; I don't have the original and the two keys I have, one ignition the other saddle bags do not work. In fact both have teeth on both sides and the helmet lock is for a key with teeth on one side only.

There is no helmet lock under the ignition. If you can unbolt it, just remove it and discard it. The small screw in the side of the radiator cap is standard. It prevents the coolant cap from vibrating off. The screw should NOT be screwed in tight. Just lightly seat it. Too tight and you can distort the coolant neck.

I have two Valks and they use different blanks. Some use the HD74 blank, others the HD75.

If you can't use the aftermarket helmet lock, just junk it, as sandy suggested. If you like having one, you can get them cheaply enough, but under the ignition switch is not a great location (engine and exhaust heat).

Hy helmet fits in an OE saddlebag (but it usually sits on the driver's backrest, unless I'm leaving for awhile).  Not a skid lid, a full DOT half. 

One of those long padlocks will work to secure a helmet to various parts of the bike.

Don't wear a full face into the bank, they don't like it.

If I have to leave my helmet with the bike, I have a thing called Helmet Hook (I think), that attaches with the bar end weight, and has holes to fit a lock. I don't know if it is still available, but it's handy to hang a helmet for a stop, and I can lock it if I have to walk away.

One of my Interstates came with something like that;  a grip cap with with a vending machine type round key lock to secure the helmet hasp in.  I used it a couple times, and the little vending machine key is on my ring with ignition key (which makes it easier to find in my pocket).  I stopped using it for fear it might stop working and I'd have to cut the helmet hasp off (ruining the helmet) to legally ride home, with no chin strap.

My Interstate has a pair of OEM helmet locks under the back of the trunk, operated by the ignition/luggage/everything key. I assumed all Interstates had that.

You're absolutely right Dave, I completely forgot about those.  

The standard Interstate (I have one) uses one key for 8 locks (ignition, seat latch, gas tank, trunk, 2 bags and 2 helmet locks under the trunk).  But on that bike, I always stick my DOT half in the trunk.

My other Intestate came permanently trunkless and solo (with Tourer fender rails with no uprights, no rear seat and a rack where it goes, and no rear pegs), and I prefer riding it with twice the miles on it the other one has.   So with no trunk (or trunk locks), I stick the half helmet in a bag.  It also has that handlebar-end helmet lock, but I never use it.

There's also the fork lock. That key fits a lot of locks!

Last time I used a helmet was 14 years ago in Michigan but only because I knew I'll do way over 100. Lost a pair of glasses checking the mirror before so I learned my lesson. Helmets not required in Michigan or Ohio where I live now. I'll take the lock off since have no key and I found location questionable too. Don't really need one.

I went out and looked before I posted, but I didn't look enough.   

I used to use that one too, but I never leave my bikes anywhere long enough to worry about it anymore.
