Turns out that seafoam in the gas saved me a heartache of extraneous and unnecessary maintenance. This thing is purring like a kitten now. The link below is a video of the idle (a little low) smooth. After pouring half a can of Seafoam, 3/4 of a big bottle of Marvel and a full bottle of Mechanic in a Bottle on around 1/2-3/4 tank of gas and running it hard and shutting it down till it cooled completely then running it again hard. The brief ride this evening was smooth and powerful. The acceleration was smooth and absolutely no hiccups at idle or high RPM (5-5500). Not sure what exactly cured it but it’s good now.
I got rid of my alluminum wings and picked up a Goldwing. Here to be a Light.
