It has to be a drainage hole...so running and insert or heli-coil covering the hole...im guessing part of the engine case won't fully drain when he does the next oil change....think it only holds like 1l  of oil...

Another option, go up 1mm on the bolt size and cut the new thread. No drilling that way.

Oil plug size is 8mm...not sure if 1mm would have done the trick....he really bored out the treads...maybe 10mm...

9mm tap is kinda of a odd size around here...mine jumps from 8 to 10...

Anyway it's out my missing hair now....i guess the yamaha dealer won't be looking at it now...not before a month....and the Kawasaki dealer were the bike was acquired...they want to replace the case itself....probably just to be not liable if something happens...

At least it has a chance of getting a proper repair now.

Come on @busster...please tell us how you would have delt with this situation....we're all waiting....lol. 

I would have drilled and tapped it after sourcing a suitable magnetic sum plug, but I would have taken it out slowly with a hand drill so to stop the swarf from ending up in the sump. Not a hard job.

There you go,  you just prove my point ...that's why your driving a bus and I ran and actual repairshop for 27 years.

Let me explain it.

This  bike has been hitting the trails since early May....how many hours do you think it has.?...keeping in mind,to keep this engine from grenadting... piston should be replaced every 40 hrs or so....now just imagine after this so call repair the engine detonate on his way home....not knowing who this kid is or his mother is....what if she's somekind of crazy Karen and blames the repair you've just did...and decides to take you to court.....

That's the difference between and amateur and a professional ...
