Firstly,.. 3 years and we hardly hear anything from you?...
I'm hurt... :'(...
...
Secondly,... you sound like you know yer' stuff...
The first booga' seems to have been the clutch cut-out...
(double, triple, check it out... because things rarely happen simultaneously)....
...if that's ruled out,... check the battery water if you have a wet cell... check the fuses, in case you shorted something with the clutch bypass... check the sidestand cut-out where you bypassed it, (it could have jostled loose)...
You know,... it's likely something simple... likely electrical...
My best guess,.. is the fall jostled the battery enough to cause either water loss, or a short in a cell... or loosen a connection...
A weak battery, will turn the engine, but not drive the spark...
Do some more tests... let us know the results...
I'll bet you have it fixed by next post...
Now,.. don't be a stranger...
Once this is fixed... you can add your advice to assist others here in need...
