Topic: K0/K1 seat latch

[.RJ]

Can anyone with one take a picture of the seat latch assembly?  I think I have all the parts according to the diagram except for #12 in the parts diagram, but it doesnt seem to latch, or release properly.

rj,if you dont get anything by the weekend,send me a pm and ill take a pic of mine.

Here's a couple pictures of mine on the bike, RJ. It seems to me the latch should work without the part you are missing, which serves as a lock to keep the latch from coming open when you don't want it to. If it isn't latching, take it apart and clean it. It comes apart easily.

Thanks - I'll give it another look this evening

Sometimes if you put bolts on too tight, the latch binds.

Can you take a pic of the latch on the seat, as well?  It seems to be functioning properly, but I just want to make sure - if you shut the seat too hard, the fixed latch catches where the spring loaded latch should go and its a pain to release.

I try to avoid slapping the seat down on mine. Just withdraw the latch bar and ease the seat down. Less wear and tear.

Probably the best answer, but I am concerned that the latch will get 'stuck' on the road somewhere.

There was a little bit of adjustment available when I mounted the latch. At first, mine was doing what yours is doing. Try loosening the mounting bolts and adjust the latching mechanism. If you recently had the hinges and seat hook off, you might want to make sure you lined them back up correctly. There's a little wiggle room on all of them. After I loosened everything up and retightened it, the seat went down correctly and latched right. It doesn't matter how hard you close it.

Looks like the latch isnt 'catching' the fixed hook unless I shut the seat fairly hard and the nits a real pain to release it (not the bottom of the bracket as I originally throught.  I'm going to adjust the bar on the bracket that bolts to the frame to see if I can fix that.  The spring loaded hook doesnt seem to be doing anything    so whats the point of it being there?

My K0 seat has only the fixed hook. The profile picture looks to me to be an aftermarket seat. Did this seat come on this bike or did you buy it to put on the bike? That does not look like my K0 hook.

From my (limited) K0 knowledge, the very early K0 seat latches didn't have the little spring loaded hook, that came later as a "safety device" to keep the seat hook locked down.

My K0 seat was missing the hook assembly completely, but luckily another member here sent me one. (thanks Dave) Cheers, Terry.

I'm going to remove the spring loaded latch and make some adjustments - thanks

I have an early K0 and it only has the one hook.  No spring-loaded gizmos.

Sorry to create a bit of a side topic here but...I just purchased a '73 CB500f that came with an aftermarket seat installed.  It also came with an "original" seat.  It's obviously not original because the latch doesn't match the one on my bike.  I have a round spring loaded latch (the proper latch for my year and model) and the spare seat has the hook like the seat being discussed here.  In the interest of saving money I'd like to keep the seat and modify it to use the proper latch.  The seat does need a new cover though but I don't know which cover I need since I'm not sure of the exact year or model for the seat.  Is the seat being discussed in this thread a cb750 K0 seat?

Yep!  I have a spring loaded/locking latch as well but it wont bolt up to the seat.  I was considering buying a fiberglass seat as well, if I do that its definitely getting the spring latch with the key bolted to it!

That's right GG, only the later K0's like mine (build date January 1970) and the K1, had the spring loaded hook. Cheers, Terry.
