So I'm having an odd problem with my 1980 XS650 that has seemed to develop within the past couple of weeks. Whenever I go to start the thing with the electric starter, it will crank over perfectly fine but won't fire up until I let off the starter button (when the engine is attempting to slow down). Now when I use the kickstart it fires up no problem. Tested the battery and it seems to be fine, it's only about a year old and I keep it on the trickel charger over the winter. Of you have any ideas I would greatly appreciate the input especially if you have delt with this exact issue.
