Specifically how many of those small balls? Seems there on the ends of all those tiny springs. I’m missing one I believe which mates with the tiny spring on the black plastic w/ small nipple ontop for lights on right side? Can’t seem to find any pics or info on these tiny parts…& of course my pics on disassembly suck! lol also don’t understand the placement of that throttle spring thing either, plus I have 1 extra copper washer(the other goes under the kill switch c-clip)

IIRC the ball bearing is 4mm, at least they are on the other years, so more than likely they are the same size.
I bought a bag of them(100) as I had lost a couple.
Pm your address and I'll mail you a couple.

The throttle spring goes in the slot of the bottom half where the throttle tube rides in. It sits in with the curvature in the same shape as the tube.

It seems like there should be a 4mm ball between the spring & the casted detent (looks like 3 little triangles if that makes sense.

I expected the throttle spring to be secured but it just sits in the cradle & that lower ext. stud must just locate it & apply pressure to grip rotation or work as a guide for cable?

That extra small copper thrust? washer is baffling too! Wtf…

That slide is pushed up by the thumbscrew under the assembly and makes it stiffer tonturn the throttle(crude cruise control)

yes, mine is a 5mm stud with a pin end & other end locking nut? Seems original…?

Yep, that's the original 'cruise control', like BryanJ mentioned: I like mine.
They disappeared in the K3 bikes, outlawed by the US DOT then (which was later 'modified' to be legal, anyway).
The screw's tip meets that deep dimple in the curved spring to hold it in the lower groove of the switch housing: that both locates the spring on the thumbscrew and allows the screw to adjust the drag on the throttle grip. (This throttle-control spring is NOT the one in your picture above: it is larger and longer, and nickel-silver colored, fits over that thumbscrew's shaft).
Mine has a steel washer on top of the spring, pressing against the bottom of the housing (outside the housing). Some of them (K1) had a nylon washer between the spring and the head of the screw, too. Lots of those split with use and disappeared, though.

[slyguy]

Thanks, my spring is correct, it’s an inch long but mine has no thumbscrew on the outside just a studded end with a locknut…maybe it was modded at some point for some reason?

Anybody know if the horn button gets a ball on the “copper/brass spring?

No oit doesn't.

The bearings went out with this morning's mail. You should have them Monday or Tuesday....but who knows 🤷‍♂️

Thank you Stu! I see how the bracket takes up the slop at button.
