Details: 1979 GS550E
23,000 miles, Emgo Pods, 4 into 1 pipe, Dyna S ignition,
Recent changes to bike: Carb rebuild, petcock replaced, new reg/rect.
It started first try at his house, ran fine, and had no leaks before we loaded it up, so I assume some things have shaken loose in between.
Tried firing it up at home and it wouldn't start. Found no fuel going into fuel filter, (even on prime). Took off tank, drained fuel, petcock worked fine, put tank back on, and bypassed filter.
The bike finally started and was only running on cylinders 3&4 and wouldn't stay running, so I shut down and started checking for spark:
1st plug test: 1&2 not sparking, 3&4 spark fine
2nd plug test: 1&2 sparking, 3&4 no spark
(Wires were not crossed!)
At this point, I suspected I may have a wiring problem as both coils were working, though intermittently. :roll: So I worked with the wiring to the coils and finally got all four plug wires to spark, but I'm not confident that they will stay that way.
I had taken the tank off again and assumed that all fuel had been pulled through the carbs while turning engine over, so I put the tank back on and put the petcock on prime. I look down to see fuel pouring out of #2 carb vent tube immediately, but stopped leaking when petcock is placed in "On" position. (I decided to deal with that later). Tried starting it again with no success, and the battery finally became weak.
This is when I buttoned everything up, washed and scrubbed the bike really well, then waxed it and I decided to try starting it again. No go!
So I hooked the battery tender to the bike and I sat on the garage floor staring at a beautiful bike that won't start for 1/2 an hour or so, and nothing came to mind. This was two days ago and I have avoided even looking at the bike since. I know I need to work on it again, but don't even know where to start any more.
What do you folks think?....
