I've removed and replaced that magnetic gate once
and in that vast body of experience determined that it was easy to screw up, possibly with HES damage if replaced incorrectly. Not idiot proof for sure but not rocket surgery either.
I do not pretend to be a BMW mechanic.
Ignition timing is bikefix.101.
The shop in NB owes you your money back.
Not fixing that bike was incompetent and forgivable.
Charging you for it was fraudulent and unacceptable.
