Nothing yet, sorry. I haven't seen my brother for about 2 weeks. I should give him a call - he seemed to suggest that one of the "old school" (non wire-EDM) machinists he knows is interested.

Could you do me a favour while you've got that motor apart?

I'm wondering about one day removing one of my compression rings, so I'm curious to know some measurements of the XFi one-ring-piston, EG:

- measurement from piston top to center of compression and oil ring
- measurement from wrist pin axis to center of compression and oil ring
- measurement from wrist pin axis to top of piston
- total "height" of the piston - top to bottom of skirt (?)
- anything else you think might be useful for comparison's sake
