I'm the "Andy" on that GN400 Yahoo Group forum with the ice bike pictured there. I should have my new combination CDI/Coil/Plug wire system by next week. Its an adjustable AC fired CDI system that I hope will give me a matched CDI and coil setup. Plus its adjustable for the advanced timing curve, which should give me the range to get the rpm up. And I should have my magneto rotor puller by this weekend. So I can pull the rotor and make sure the timing is correct, or at least prove the rotor key has not sheared.
