Reliable idle

that sounds like a good way to breathe some life into these tired bikes.

I have a new wire harness, new hand controls and wire terminals. I have zero resistance on my red/yellow coil power wire.

In my case it was in fact the carbs.

BTW, if you go on youtube and search videos for George AFB I posted up some old 8mm movies that I took while I was in the air force of the life on the flightline at GAFB. Plenty of F-4s. We had C, D, E , F and G models. Also Thuds, 106s too.
