OK soon my motor is getting sent to Quebec to get a new crank bearing pressed on and the cylinder getting bored out. I have one question about the crank bearing. I hear that most racers drill more holes in there crank bearing so it allows more oil to get into the bearing and faster providing the bearing with longer life. Since Yamaha is know for having the bearings wear out fast. I was wondering if I would be able to get this done to my new bearings by myself or would I have to ask the company to do it for me. Because I'm not sure if it would have to be centered and or measured so it would be balanced or not.
