Please pm me your email address.
Sorry about not seeing your request.
I've had a serious tragedy. My shop burnt two weeks ago.

The "Oiler Mod" I am familiar with relates to early YFZ450's and it probably effects the 660's of the same years too.
For the 450, prior to 2007 or so, there was a problem with the crank not getting enough oil at high revs - so the story goes.
The fix is, when you rebuild your motor, the case has to have a new hole drilled in it to allow for proper flow and then the oil pump gets replaced with a higher output model from the later years. The result is a new squirt that hits closer to the wrist pin.

At least that is how my highly concussed brain remembers it....
I had my mechanic do it to my YFZ a couple years ago.

Good day WillyKiller, I trust that you are well.

I would like to find out whether the details are still available for your oil mod to keep the top of the con-rod lubricated?

My email is [email protected] if it is still available. I also sent you a PM.

Kind Regards
Dion
