What should I be worried about?

[Jordan]

Are they bits of kickstart return spring?

It's all the same bit.

I did recently implement the leaf spring repair. I then went back to add a locking tab washer to the nut that holds the inner and outer clutch hubs.

There seems to be finished edge on this with a 45 degree chamfer if that helps identify it. It is 7mm wide and I would guess it was part of something 20mm in diameter .

Time to remove the clutch cover and have a look,,,,,,

" How worried should I be.... "

____ Not much.


" What should I be worried about? "

____ Getting the rest of it out.
__ You never mentioned how many leaf-springs were installed in your Duke-motor (before you went-in & installed your new ks.kit).
While the 4-speed versions employed only one leaf-spring, the (pre-66) 5-speeders came-stock with 2 springs. _ And it was a common-practice to install a third spring, whenever replacing bent/sprung leaf-springs. - (It's not an easy task to install more than three, as their mounting-bolt would then not fit-through them all [without some extra taskful fussing-around] ).

____ Firstly, I ought point-out that your combo-pic of three separate pictures (of the very-SAME single piece), combined into just one pic.post,, can possibly be confused as being just-merely ONE pic of three different objects, (without adding any note of clarification presented underneath your pic.post -[posted picture] ).
__ Anyhow, it takes somebody like myself (who can identify every single part from any [stock] OHC.Duke-model), to be able to tell you what this piece is (for sure)! ...
It's a piece of kick-starter leaf-spring, apparently busted-off from it's right-side pressure-arm, (as can be noted in the pix I've posted below). _ If I'm correct (as I believe), then you should find that your broken-piece fit's -('spoons') against the same section-area of the leaf-spring you had removed (when you installed your ks.kit).

You are right Bob, I was in too much haste to get the photo out for identification and I failed to tag the three views as being the same item.

Good call too on the ID of the shard.

I have a 5-speed gearbox, and the previous owner indicated he had been in there to double up the leaf springs. He made no mention of having found two, and I suspect if had found two he would've upped the ante to three springs since this was his tack at solving the problem.

Perhaps though he felt that two new springs would be better than two old springs.

With your diagnosis on the iPad I ran out to the garage to look at the old leaf springs which are in a drawer since being removed in favor of the coil spring repair.

To my surprise both leaf springs are perfectly intact.

This would seem to indicate that there was a third leaf spring somewhere in the time line of this bike, likely having been removed when the PO attempted the dual leaf spring repair or at an earlier attempt to repair the kick start problem.

I still keep in touch with the previous owner, I intend to inquire about his recollection regarding his spring repair.
