Ok so I'm rebuilding an older bike and I was having ignition problems -- particularly I lost spark - had it and now i don't...spent some time and 6 beers last night tracing over the system - key, switch, etc....traced it back to the coil - under the flywheel - I had no readings coming out of the wires so I pulled the flywheel and found that the solder had come loose and the wire pulled itself out of the coil - my question is the wiring is old and I was considering running some fresh stuff - anybody know the gauge - anything special I should know? I'm sure I can check tonight when I get home but if I can find out now and pick it up on the way home from work, giddy up.
