Bike wont start, New cylinder

[Narsil]

I know this all should be good from before the rebuild, but if you run out of ideas, I'd say test the stator (disconnect the plug from the stator, and check for resistance between each set of two of the three yellow wires, should be the same reading on each pair, and then check resistance from each yellow wire to ground, should be infinite resistance, if it shorts to ground that's bad). I think also the voltage regulator is a common fail point, but usually it will still run for a bit, but the voltage slowly climbs until it hits like 18 volts and then the ECU stops operating and the bike dies.
