Did you replace the O-ring between the case and cam plate? If you forget it or it moves on install, you'll lose PSI.
Did you take the spark plugs out (short them too) and turn it over to see if you got pressure? (about 15 seconds) Let the starter cool, and do this about 3-4 times, allowing the starter to cool after each time.
Did you pack the pump with lube prior to reassembly?
You Do have oil in the bike too, right? (Silly, but .....)
There's also a "wave" washer behind the oil pump, that if it falls out and you miss it, you'll lose oil pressure upon restart.
