Sorry, I've no experience of the product Colin - it may be terrific.
The thought of losing the sump plug on a motorbike at speed though does not appeal.
For my money, if there was room available, I'd look at tapping oversize: 13/16 BSW/ BSF, 1/2" BSPP or 7/8 UNC all use a tapping drill around 18mm.
Helicoil by all means but I'd take care to seal it in place.
I realise tapping it may be a challenge. Last time I had to do something like that I held the tap vertically in a pillar drill chuck and clamped the workpiece up at the correct angle on the drill table, then rotated the tap in by hand. Keeps it nice and true. Sorry if teaching to suck eggs.
