And replace your bolt crush washer every once in a while, it helps.

Technically an M6 bolt is specified 6' lbs. Snugged to hand tight is appropriate. If you are suffering from a seeping leak, over tightening the pan won't solve it. Gonna have to remove the pan, scrape the surface very clean and install a new seal.  If you've done that and still have a leak, remove the pan and check the surface for square/level using a metal straight edge in multiple directions across the whole of the surface.

If you on find a problem, then correct as needed.

IF all of this is meaningless and you just wanted a spec, apologies. Thought I might "head off" any issues by presuming the reason behind your question.

More info, the better !!
The pervious owner had a seeping leak when bike was running. I removed the oil pan cleaned it and the surface, installed a new o-ring & bolts. time will tell.

I hate pervy owners.
'Then' and 'than' are completely different words and have completely different meanings. Same with 'of' and 'have'. Set and sit. There, their and they're. Draw and drawer. Could care less/couldn't care less. Bought/brought FFS.
