You can turn up the oil pump setting for a rebuilt efi then readjust it back after break in.
As for the original topic, if the previous owner didn't store it properly, as in fog it or run it until hot every month or so, then yes there could of been moisture built up on the crank bearings. Unfortunatly, the damage is already done, the bearings will pit from oxidation and will fail prematurely. So basically you have what you have and there might not be a problem at all, but if you drop a crank bearing in the next couple of years, you know it was probably due to improper storage. PS, when you drained oil on your two stoke dirt bike, it was transmission oil, the crankcase is a seperate sealed section lubed by two stroke mix.
