Lol, what triplets...
Well just for starters I just broke this piece down when I played it, there is only 4 or 5 motif's here. Just get them working on different hands smoothly and slowly (there are a couple of inversions or backwards versions of the motifs too..) once you get them down it is just a matter of where you start from for each motif and go from there. Starting at measure 18 I just worked two notes on the top bar in a 3 1 fingering for each note on the bottom, after two or three passes it just became natural. The book I have shows them as two notes per, I am sure you can double that

It's also a great piece for working out any thumb under issues. But scales and arpegios work better for that.
I like the Kalmus version, I have some of the same inventions in an Alfred book but this is better.
If you have access to a recording of the inventions (I have the Gould version) check out the simfonina #2 it really is a nice piece, if I ever get back to working on the inventions I will do that one...
