So, if I need an over-sized oil drain plug that would be an M14-1.50, ...correct?? If so, then what size drill bit do I need for M14-1.50??
Please advise. Thanks a million!!

Metric ISO thread 14 x 2,0 you have to drill 12,0 mm
Metric fine thread 14 x 1,5 you have to drill 12,5 mm
I add a drill chart for all kind of Drill-Ø for Threads and Minor-Ø of Nut Threads

As that other thread linked above references, there are various ways to fix the bike.

1) get a new oil pan off ebay.
2) drill, thread for oversize drain plug
3) helicoil for original size bolt
4) use a solid insert to repair threads
5) use a self tapping drain plug from the auto parts store. No tap necessary.
