Interesting, I have two engines, one a Japanese domestic model, the other an Australian model, both just have an unused casting lump, no hole.

lol thats good to know..i did some research as well and looked on ebay even looked on my mates trx..could be for a bracket of some sort.. glad it's not missing a bolt..but just have to change the oil filter.
