I reread your first post, was it a Kawasaki recommended 2,000 mile break in procedure?
Nikasil is tough and hard, I installed JE high-compression pistons and rings about 10,000 miles ago. Before that I had installed ZZR 1200 pistons and rings (11.0:1 CR with base gasket removed). A simple wipe-down of the cylinder walls with scotchbrite removed the dull gray micro wear material in the crosshatch and the crosshatch was factory new. The cylinder bores in every dimension spec'd smack dab in the middle of factory specs. Both times I've simply installed rings with the pistons and they've sealed up fine.
Point being, I take it out and run it up and down the rev range within the first 5 miles once it's warmed up and don't let the idle drop below 2000 RPM at initial startup. Keep on riding for as many miles as I feel like, taking it up the RPM scale and letting it brake back down then taking it back up, always keeping the rings under a load from acceleration or engine braking. I do keep the initial rides to 20 or 30 miles, letting it cool down fully and then taking it out again the next day. I think a few heat cycles is a good thing early on, but I do believe everything has seated and mated within the first few miles after startup.
Not a drop of oil consumption in over 10,000 miles with the recent pistons/rings over the past two riding seasons.
