First time bike owner here, so please bear with me. I was gifted a 1978 GL1000 that had not ran in over a year (81,000 miles). Previous Owner (PO) thought it just needed a new start button. I finally bought the entire Run/Off/Start housing, and a brand new battery. I also put in 4 oz of SeaFoam into the carburetors and let it sit for 24 hours. I drained the float bowls before trying to start the bike, added a gallon of gasoline and turn the petcock ON. I also added 2 quartz of oil into the engine since I could not see through the indicator glass how much oil was in there. This is me trying to start it:
The engine won't crank/turn. You can hear the starter, but that's about it. Like I said at the beginning, I'm pretty much a noob when it comes to motorcycles, so I'm not too sure where to go to next to try and figure out the problem. Here is what I'm thinking so far:
- Bad Spark Plugs: I will take them off, clean them off, check that they are the correct size, and see if they spark
- Coils: I've read that these could be the problem. But I have no idea where they are, let alone how to test them! Any pointers will be appreciated
- Too much oil in the engine: Like I wrote above, I added two quarts to the engine, but I still can't tell if there is too little or too much oil. I plan on just draining the entire thing and re-adding the recommended amount 3.8 liters (I think)
- Flooded Engine: Not too sure about this one. Even though the gas line was ON, gas was not dripping from the petcock when I disconnected the fuel line. I went ahead and added 4 oz of gas from the fuel line (disconnecting the fuel pump) into the carburetors. I had the same results and drained the float bowls. I collected what was being drained and got back a tad bit under the 4 oz I put it in. So I don't think the engine was flooded
Finally, when I uninstalled the old battery, this cable was in the back of the battery, disconnected
I will try to take a picture of it. Its in the back part of the motorcycle (by the back tire), and it's part of the set of wires to go into the tail light. It has two prones and they are covered by a plastic black housing. Does anybody know where this is suppose to be connected too?
Thanks to everyone who reads and replies to this!!!
