During a take off run, following a mag check for normal RPM drop, the engine miss-fired continuously following rotation and lift off. I immediately pulled back on throttle and let the 912 XP settle for landing. I ran off the end of runway (2,400 Feet) with no damage. Transition from runway end to farmer's freshly planted field was smooth (large wheel option on Pulsar). The problem turned out to be my failure to return the ignition switch to full right position detente between "left" and "both" positions. Though I initially had full power at the beginning of the take-off run, vibration may have caused enough of a change in switch contact position to lead to the problem. When the Pulsar rolled to a stop, I sat quietly and reviewed my procedure and discovered the problem with the key position. The problem has not reoccurred since that eventful flight. It seems logical that spring loading in the switch, if provided, should cause the selector to prefer one detente or the nearest and not settle on a mid-position between detentes?
