I have a lance GTR 50 that is about 5 years old. 150 miles. Got it going for my daughter to use for a work vehicle. It has been setting for a couple years. Drained the old gas. (That was a trip. Never been around a tank mechanism that won't let he gas drain.) Started up. Was running fine. She accidentally pushed the kill button. While driving it around. It did not have a battery in it at the time as we had jumped it. So we jumped it again and it started right up. Then went dead. Thought it was out of gas. As we had put just a little bit of gas in the tank. I put more in it. We ran the starter to prime the carb. It started for about 4 sec. Then quit. Nothing now. No spark. Every once in a while we see a little bit of spark but nothing like it had 30 min earlier when we were looking at it. Changed plugs. Wondering do the kill switches go faulty so I disconnected it at the switch. Which I believe would dismantle the switch function. Nothing still. Prior to that I worked the kill switch 40 or so times. I had spark. Put in the plug and it started. For about 5 sec. Then no spark. Coincidence. Started to look at the Coil. Here is what I saw so far. For what it is worth. What next? Do these measurements tell anything. The coil has two small colored wires going into it. Would very much appreciate some help here from someone in the know. Hate to just start buying parts.

Since you said this scooter has set for 5 years the first thing that needs to be checked is electrical connections from the kill switch to the battery. Just a poor ground will cause no spark. Check the battery negative cable to the frame, make sure it is free of paint and rust. One of the wires going to that coil is a ground also. The other wire usually black/yellow will go from your coil to the CDI. make sure all connections are clean and also the ground (usually a green wire) is making good connection.
You also need to put a battery on it so you won't cause the R/R to load up and eventually burn out.
The kill switch function is a grounding out the CDI and the black/white wire to the CDI goes to the kill switch. If you have unhooked it then that's not an issue but if the black/white wire going to the CDI is worn and has a bare wire grounding out then a no spark situation will occur.
As far as your reading coils are all over the place to try to test and your reading of 4 ohms on the primary side does indicate it is good but you need to test the secondary side and here is a video showing how:
Now that is also another thing to check and it's the spark plug cap or boot that goes on the spark plug. They can get loose and/or corrode, take it apart and check it out.

Thanks I will check things out. Connections do not seem to have corroded much. What is weird is it ran so good. Sound great and then. NOTHING nada. Spark plug boot looked very clean inside. And tight.
When the video had it set on 200 he was getting 3.5 ohms. Mine is saying .4 ohms. Right?
