Did you have plugs installed when you checked spark?

These crank trigger ignitions need some compression, it's how they determine the cylinder phasing.

A guy at HD once told me it was based on the MAP sensor. But I don't think that's right, I think it's based on compression.

Bottom line, and I've seen this on crank trigger bikes that run perfectly, you remove the plugs and put a plug into it's wire and lay it on some metal to check the spark in the traditional way, and you get none. Whether it's the loss of compression or the loss of manifold vacuum that's causing it, I'm not sure. I suppose I could run an experiment to figure it out, but I'm not that curious.
