Greetings my fellow XSers. I'm really happy to find this site. So here is the problem. I put on a new coil, wires, plugs. Rebuilt the carbs after a long Wisconsin winter. I was trying to adjust the air/fuel mixture. I started the bike, warmed it up and pulled the left plug wire. I went to adjust the A/F mix and the engine didn't shut down when I turned out the screw all the way. Put the wire back on, readjusted the screw to 2.5 turns out from bottom. restarted the bike and pulled the right plug wire. Engine dies. Another half turn out, plug wire back on, start engine, right plug off, engine shuts off. I have spark at the plugs. So I think its the pickup coil but I'm not sure. I don't know if there is a procedure to test it. I guess it doesn't matter because a pickup cannot be found, ANYWHERE! PLEASE HELP!!!
