Given the absence of the possibility of harvesting the benefits of civilization in the middle of the jungle, I'd favor MacGyvering the situation.
I'd certainly trust your steady, sure hand in the effort--most unlikely you'd butcher the "donor" bikes providing the clutch plates. I would not consider the donor bikes at risk; certainly not at the price of abandoning an otherwise completely functional bike, with only a clutch malfunction, to the monkeys of the jungle.
And, since the case cover had been removed from the disabled bike anyway, I'd CERTAINLY try shimming up its clutch spring bolts in hope of riding it out. If shimming were unsuccessful, I'd then look to the donor disks.
Only a handful of humans have EVER crossed the Darien by land; fewer still on motorized vehicles. Sending someone to fetch parts and return seems an unlikely option, to me. I'd be inclined to resort to the less-than-optimum practices of the field-expedient repairs mentioned in the emergency situation described.

My bike, my attempt at repair, yes. I might even attempt to whittle a wooden spacer plate out of a tree stump!
But I wouldn't risk 3 other engines. I would help push, pull and drag those 3 other bikes to civilization, so they didn't all suffer the same fate. And then hope to take proper parts back to the wounded warrior.

Apocryphal Anecdote (Emergency "Cannibalizing")
If, changing a flat tire for a spare on your automobile, you somehow lost the lug nuts for the affected wheel, would you consider "borrowing" a lug nut from each of the three remaining wheels to temporarily mount the spare?
Certainly not, I should think; ALL wheels might then come off!

MacGyver never curbed his initiative, expediently repairing things when no more favorable alternatives were in sight; some riders are so inclined, in EMERGENCY situations.

MacGyvering The Clutch
MacGyvering the failed clutch (as in, Monday-morning quarterbacking), I see another possible remedy (along with the previously-mentioned shimming of the clutch bolts):
FOUR KLR650s were involved in the expedition, IIRC. THREE had serviceable clutches. Each of the functional KLRs could have EXCHANGED one fiber clutch disk with a worn disk from the malfunctioning KLR.
While clutches on all machines would be compromised to some extent from the exchange, they might still function until a source of repair parts could be reached. This tactic, along with shimming clutch bolts, might have enabled a finish as a unit, instead of abandoning a bike in the jungle . . .

What an adventure!
I wasn't there, so I will NOT presume to second-guess the actual participants regarding the clutch failure. The KLR650s (at least the earlier models; I think latter-day ones lost a couple of disks) have extraordinarily robust clutches; failure/malfunction rate low, given correct operation. My theory . . . the current population remains basically unfamiliar with manual clutch operation; FEW automobiles have "standard transmissions" with manual clutches . . . the KLR clutch is NOT analogous to an automatic transmission, the latter delivering power through a fluid coupling.
If a manual clutch is slipped excessively, it WILL fail. Choosing lower gears when appropriate, and slipping the clutch minimally (preferably, only at start-up) extends clutch life.
All this said, from the looks of the clutch disks in the images from the blog, that clutch was a textbook candidate for the, shim-up-the-clutch-springs field expedient to extend its life. Maybe these adventurers tried that approach, but . . . no mention of any such attempt in the text I read from the link posted.
The sacrifice of a KLR for such an expedition isn't a particularly great price to pay, IMHO; the bike might have been saved, but . . . as previously mentioned, I wasn't there; any such suggestion remains total conjecture on my part.
Congratulations to the party on their success!

The four Americans who were going through the Darien Gap had to abandon one of the KLR because the clutch failed. It seems that they had been abusing it a lot since they had been using side cars on the way to Panama and did not check them.
There is a legend that says that Darien's Gap always keeps something. This time it was a KLR.

Since this thread has awakened the latent adventure interest among forum members, I commend to them this overview article on the Darien Gap "riding area:"

A couple of crossings were made via Rokons; Ed Culberson did it on a BMW R80:
(Click on the green box and you will be directed to a blurb for the book, "Obsessions Die Hard," an account of the journey.)
Crossing on KLRs? A noble challenge!
