The bike will start right up when dead cold. Seems to only run on two\ncylinders with the others kickin in and out. After about one minute or\nless the bike will die and not start back up. I get no spark showing\nwith my inductive timing light but a spark plug setting on the frame\ndoes show spark. I have tested teh coil and they fall within specs\nwith the ohm meter. I have also tested the spark generator with the\nohm meter and it reads 488 instead of 480. Seems close enough to me.\nThe spark box units are not testable according to my book. I have\nbeen quoted 95 for each spark box and 55 for the generator. Since I\nhave never rode this bike I am not interested in spending 250.00 bucks\njust to seek what kind of shape the rest of it is in. Anyone have a\ngood idea if its the spark generator or how I can test the spark box\nunits?
