Just wrote this in another post, so "copy" "paste" and here ya go:
First adjust your valve clearances (engine ice cold), then timing chain tension, check your spark plug conditions and gaps, bench sync the carbs, set the air mixture screws to default per the manual, now set your points gaps and ignition timing, then run the bike till you reach a good operating temp (like 20 mins or so), finally synch the carbs with the engine warm (pop a fan in front to keep from overheating).
Good luck. Enjoy.
