However, the part numbers are different. People that have more experience with it might want to chime in. But, if the Dakar plates are usable, you might have a few more options in your search.
As for squeezing a little more out of the original plates, you might want to use thicker oil, rough up the plates with coarse sand paper, make sure you have play in the clutch lever (no pressure on the lever at all), and use the clutch only to get going,- shift gears without using the clutch. Keep the clutch engaged and as cool as possible. No off road and no uphill. All off this, of course at the risk of getting stuck again.
One more thing, in many countries, where parts are considered much less disposable than in our western world, there might be services to renew the friction lining of the plates. One more direction...
Let me know if I can help.
P. S. And after thinking a little more, I am leaning towards: you might have glazed the plates (as someone mentioned), as opposed to worn them out. In other words, you still have the thickness of the linings, but the linings are so smooth that they provide little friction. This usually happens from overheating. The surface just melts and is smoothed by the metal counter plates.
Again, roughing the surface would get you going, but you would have to work pretty hard at it since the glazed surface is very very hard.
I am hesitant to suggest any kind of washers, screws, or anything else that redesigns the original clutch. These kind of fixes usually get you stuck worse than the original problem.
