Gauges were acting up going On and off while riding. Thought maybe it was voltage regulator. Changed that and realized the valve spring had broke and took out the piston and cylinder. Did a full rebuild in the top end with new Pistons and bearing and a new jug. Go to start it and it ran for a moment and started knocking on the mag side which has the new cylinder. Pulled the plugs and the pto side is steaming like it's running but nothing out the mag side. Checked for spark and both caps have good spark. Any ideas what might be wrong or what I can check.
