Coil pack question

My friend took off my coil pack to test them on his bike. He wound up putting them back on mine but I wanted to verify if the 2 wires have to go on a certain way or not.

This question came up a long time ago, and I`m sure it was decided that it doesn`t matter which way the wires are connected.

Alright. Any ideas why the bike wouldn't start? I replaced my stator last year and haven't had the bike running since before then. I'm going out later to get a tester for the spark plugs to make sure I'm getting spark. I did get some white smoke coming out of the front manifold and a tiny bit out of the air filters. But it just will not turn over. I verified everything was connected and tight. Whats the next thing to look for if its verified spark and fuel are working?

You say the engine won`t turn over. If it won`t turn over, a spark tester will do you no good. Or do you mean the starter turns the engine over, but it won`t catch and run?

Make sure the battery is fully charged, or boost it from your car battery and try to start the engine.
Since you are ear shaved it is easy to give it small shots of ether/starting fluid if it turns over but still won`t start. If it catches and runs for a second or two on ether then dies again, you know you have spark but are not getting gas.

Once you get the engine running, then you can determine if the stator is charging.

Not sure what to make of the white smoke, especially if the engine is not turning over at all.

Is your red engine stop switch set on run? If you have spark and fuel it should start. Just use a long phillips head screwdriver to check spark. Put the tip into the boot and ground the shaft to the engine.

Yes the motor sounds like its trying to turn over to start but something isn't right and it doesn't fully start up. The switch is set to run. I haven't tried to hook up a car battery to it yet but I do have my battery on a trickle charger and I wind up killing the battery after about 10 attempts to start it.

Outside the box I do have about a full tank of gas that has been in it since last spring. Also the carbs might have had some fuel still in them while I was doing the work. Do you think I should get the carbs cleaned up? And put fresh gas in?

I tried the spark tester today but the battery was just about dead but I did some what see it getting spark.

Drain the gas and pour it in your car. The larger tank volume of the car will dilute the old gas from the bike and not hurt the car.
Put fresh gas in the bike, along with half a can of Seafoam fuel treatment.
Pour some straight Seafoam into the carbs through the lines from the tank and let it sit for a day or two. Might have to drain carb bowls of seafoam, and let it fill with gas before it will start and run.

Starter sounds like it may be weak too. How many miles on the clock?
Might need a rebuild kit. This one popped up on the first page I looked at.

How do you drain the bowls on the carbs?

I drained the bowls and emptied the fuel tank, put fresh gas in with about a half can of sea foam in the tank. Also decided to swap out the plugs, since they looked wet. I'll give it a shot tomorrow and also try and hook up a car to the battery and see if the battery might be on the fritz. Any other suggestions or other things I can look for?
