Having read through this thread, I am puzzled by the bottom bracket length. I have always understood what is needed is a straight chainline. If you have a 120 OLD rear wheel, the chainline will probably be around 43mm. Then the distance from the center of the seatpost to the middle of the chainring would also be 43 mm. I would be surprised if a BB spindle greater than 107 mm would work. Stripped down as yours is I would think it would be around 22 lbs or less, hardly a porker. I think it is a very nice bike. BTW., the late great Sheldon said an ISO crank arm will work fine on a JIS spindle and I have found it so as well, although JIS on ISO spindle not so much.
