OK, I need some advice from a clear head. The wiring problem I've developed on my 73 has got me completely stumped. Last fall I rode the bike approximately 3000 flawless miles and parked it in the garage for the winter. The bike wasn't touched all winter. The boyer has had the plate drilled and screws replacing the solder connections. The black box has been swapped to ensure there isn't a problem there. The wiring was gone through from front to back of bike to make sure there isn't a short somewhere and I can't think of a wire I've missed. The ignition has a bypass from the ignition switch to the boyer direct omitting the harness for the most part. There is a brand new good fully charged battery installed, old crusty ignition switch was replaced. The symtoms are the bike sparks intermittently. Will start first kick and sometimes die immediately and not restart again for an indefinate time, no rhyme or reason to it. The bike will fire and run for say 20 seconds or at one time rode for 2 miles and like the snap of a finger loose spark and die. With the plugs out if I turn the ignition switch on and off the boyer sparks , but not always, when the bike is kicked there is spark sometimes, then it is gone. Can anyone tell me what has been missed or if I've done something wrong. I am at a loss and have had a good friend that I consider very good as a troubleshooter and mechanic look at it and he to is at a loss. As he put it last night "In thirty some years of wrenching I've never had a bike I couldn't unf**k, but this thing has got me"
