This will help answer some questions.

I'll machine the top of the cylinder to get the piston as close to top of deck as i can. I'll also machine the sides of the skirts like the Je pistons are. The new Wossner piston is machined even more than the Je. I just wish the wossner had higher compression. They are incredibly nice pistons

I would take and machine off the bottom of the cylinder if possible.
CP makes some really nice pistons as well.

i could machine the bottom of the cylinder. wouldn't be any harder than machining the top for me. does cp make any pistons for these motors?

Yes they do. If you are taking material off the bottom of the clyinder, be sure that the sleeve doens't hit the crank webs.
