Hey guys,
I did some searching "bad iggy" ect... but nothing matched.
73 H1D properly maintained.
Bike runs great - however - sometimes it's difficult on a cold start - when it gets running all three firing however it smells rich (and some backfires) and won't idle. Nothing has changed - been reliable on long trips. A while back I posted thinking it was a bad coil but It hasn't acted up since then. Today I spent 3 hours unplugging and cleaning all the iggy - coil - battery - fuse and ground connections. New plugs - carbs clean ect... It' strange because bike runs great and then like a light switch it acts up. Tomorrow it will probably run normal. btw - fresh Sunoco gas - same as in a my vehicles.
Any ideas???
Thanks in advance.
These symptoms are the same that i have had on my H2 in the past.
Use non-resistor plug caps. Resistor plug cap when they start to fail cause starting & running problems.
Earth ( ground ) wire from stator broken ? check it.
Check resistance values of the ignition charge coils in the stator.the low speed coil will cause your problems.
Also check these coils with a `Megger` for leakage to earth (ground),there should be no reading for this test.
Fit extra earth (ground) wires between engine & frame.
