I have a jawa 207 that has been sitting for a while. I think it need s a new thyristor or 6vbattery. The piston sounds dry. I have a very weak spark only felt if you hold the wire when turning it over.
I am so desperate. it just sounds like its not getting spark. The magnito is gennerating because i have been shocked by it. all the bulbs are working and i set upbike like the wiring diagram I have for it.
