Bike Carbs

Sounds like you are using the original hybrid esc system fitted to the carb Sierra's. In which case you will need to retain all the existing sensors for it to work correctly. Water temp, air temp, map sensor.

My engine was orignally from a fuel injected Sierra. I binned all the CFI except for the EDIS module, and wired in a megajolt to control the advance.

As for the tubes I drew the manifold on the cad system at work and altered it until I was happy with it. I then produced flat patterns of the pipes on paper, cut them out and wrapped them around some tube. Simple job of cutting with a disc cutter then.
