Things don't always go to plan... I tried to starts it... I had a spark, and lots of backfires, but it would not run. I checked a few things and came to the conclusion it was the pickups... I wasn't sure if it was the actual hall sensors, or the magnets and spacing. I decided to try the magnets and spacing first, and it turned out to be that. not sure if it was the strength of the magnets, or the spacing (I suspect it was the spacing) but either way I had to re design the rotor. soon as I did this, it fired up and settled to a nice tickover. I also breathed a sigh of relief as I had put a lot of effort into the exhaust and didn't know what it would sound like! To me it sounded awesome! here is a short video.
