Mystery hole/missing bolt?

[Sami]

Hey, I did't found answer from Clymer or Haynes so does anyone know what should be in this hole? Its under the carbs next to oil line. I think it could be some bolt, but why and which size? Pic related...

sometimes when they build motors they put holes in the block for things they were going to put on but never did, so if it don't leak or anything like that i would just leave it

sometimes the holes in engines are for other purposes like market requirements.

Here is better picture... I hope its not some banjobolt which sprays oil to some very important place?!?

i think it was an 80mm long 5mm flange head hex bolt. i measured the bolt a few days ago on a gsx-r 750 motor.

Edit: it's a case bolt not an oil passage

Thanks, I try that!
