Jack,
I have two drill bits. One is a standard short length and one a "jobbers" length that is long enough to pass thru the engine, frame and then some. I borrowed the drill bits from work. If you like I can check the length and availability and let you know. I used the short drill bit to drill thru the frame and part of the way into engine on each side. Then, I used the the long drill bit to drill all the way thru from one side. The new 12mm bolt easily passed thru and engine with no issues. As a side note, I drilled a short distance then removed the drill bit and blew the chips out repeatedly. This process worked well.
I also did a couple of things that may or may not be necessary depending on what you encounter. With the bike on the center stand, I lightly supported the engine with two hydraulic jacks before attempting to remove the rear engine mount bolt. When I removed the bolt the engine rose up about 1mm or so in the frame. This was mainly because of the rear shock was still completely mounted on the bike. The top shock mounting bolt is attached to the frame, the bottom shock mounting bolt is attached to the swing arm and the swing arm is attached to the engine. You get drift?
Anyway, as I said, you may or may not encounter this situation. What I did next was use two jack stands I had made to support the frame from under the seat just ahead of the passengers foot pegs. I have a plastic coated pipe that passes under the frame into a right angle ear that is welded to 1" threaded rod on each jack stand. I was able to gently lift the bike off of the ground at the center stand. Then I placed a piece of wood under the rear tire on the floor to support the swing arm and removed the bottom shock mounting bolt. Still lightly supporting the engine underneath with two hydraulic jacks I was able drill thru the engine essentially allowing it to "float" somewhat drilling the new hole.
This is way more than what I had initially intended to do, but it worked out okay and I was able to successfully drill the rear mounting hole with no issues. Also, the instructions I received from TPO said that the nuts were 14mm. They are not. They are 16mm. I didn't have any 16mm sockets, so I had to make a trip to get those as well. Sorry for the long story. Take it for what it is worth. I hope it helps. Good luck and let us know how it goes.

Wayne,
Do you have the bit for enlarging the openings? I looked on McMaster-Carr's site a couple of days ago and found a 12" bit for around $30. If you don't have one, then I'm going to post a notice and ask how many are doing this mod. Perhaps a few folks may want to combine finances and do a group purchase of the bit.
