Hi,
I´ve recently got a 1979 GL1000 in pretty good mechanical condition (good compression in all 4, no smoke, good transmission etc) but it needed some care and love, mainly carb cleaning / synching, ignition timing/points etc.
Now carbs & plenum are clean and rebuilt, and I have also installed a Dyna S ignition. Problem is that I cannot make cylinder #2 fire. Went through the carbs again just in case, and nothing changed. All 4 plugs are new and firing, but one strange thing I´ve found is that the spark in the dead cylinder #2 is much stronger than the rest. If you unplug the cap, you can hear the spark. If you bridge it to the cylinder head, the spark is more than half inch long! If you just hold the plug cap with one hand and put the other hand close to a grounded surface, you get a spark! This doesn´t happen with the other plugs. No visible spark from the cap to the head when plugged. Also tried to swap connections between cylinder 1 & 2, and #2 is always the one that doesn't fire. Any thoughts? Thank you!
