I just ordered oem parts for my stage 1 rebuilt. Parts are from japan.webike.net, and price is about 60% after tax compared to EU prices. Only these parts are not enough to get free shipping, but this shop has a lot of useful and interesting stuff.
Here is my list for engine rebuilt, maybe somebody will find it useful.

next week, pistons are in czech and just in process of tax duty. Oem parts are shipped today from Japan, it seems that bike can be ready during march :-)
Got the pistons today :-) They are approx 65g lighter. I hoped for their X design at the bottom, nevermind. Bore is 98.5 mm, compression should be about 11.3, maybe I will measure to check. Hope there will be enough space for valves, but original piston was used as template ...

There is no need for it, crankshaft is balanced separately. You can use whatever pistons and rods you wish, if they are same weight front and rear. V90 is partly selfbalancing it.
I would be more scared with flywheel lightening, but it is safe for the same reason as above.
