I found the problem - one of the wires in the ignition switch came loose. Soldered it together and the bike started right up. Now I have a new issue - cylinder 3 is not working (or so it seems - the header pipe is cold). The carbs were freshly cleaned and floats and float needles were replaced, all the jets checked and cleaned, all the openings blown out and free of any debris or deposits. Where should I start? Compression? Spark plug? And thanks for all the info on the continuity - will use it in the future to troubleshoot things. J
