Ignition problem XS400 12E

[Tibor Vecsey]

Hi Everybody, My XS400 12E (1982) recently does not want to start, or when it does, no gas reaction for rev. No fuel problem. Spark ok, ignitor box seem to have connections, no damage.
Any idea what should I check?
Many thanks!

It's fuel or spark. Check spark on both sides. If it shows spark, it could still be weak, so clean and check your spark leads, cap, plugs and measure both coils per the manual.

If there still is no start, it is probably fuel related or ignition timing.

Thank you for the answer! Spark wire, caps and plugs were recently exchanged. Fuel flow ok, carbs were cleaned. So coils could be a problem or ignition timing. I think I should look for a good electrician. (I am not an expert on this )
