Well it was resolved.   When they replaced the stator they reused the old gasket and it leaked.   (probably forgot to order one with the stator order)

The starter ended up not getting replaced.   I had told them them to save all of the old parts.   I was told the next week that the tech was comparing the old starter to the new starter and decided to look into the old starter - he found a "sticking brush" so he was able to free it up and I didn't need a starter after all.
After nearly three months all they ended up doing was replacing the stator and fixing things that it didn't need.   After some arguing , I got the invoice reduced to $360.00.  (Supposedly it was over $600.00 and they presented me initially with $490.00)
It runs and drives, just in time to put away for the winter

Over 6 week’s into this.  They got the new starter in and it starts.  BUT NOW.... they tore some kind of gasket and it has to be ordered

It took over 2 weeks for the stator to arrive.  They installed it and said it started - once.   The starter went out.   I didn't get to hear it and now waiting for a new starter.

I checked with them late yesterday.  The tech had already gone home but they told me has ordered a new stator. Waiting until next week (hopefully) for the next news

Well, the dealership replaced the CDI and still no spark.  Now I’m waiting for them to diagnose it again

They called me and said the CDI is bad.   I decided to have them replace it and the burden of correct diagnosis lays with them.  They had to order one and it should arrive this week.

It was a tough decision but I have decided to take this to the local dealership to see if they can figure it out.

Thanks for the thoughts mrbios.  The kill switch works because I can see battery voltage at the ignition coil until I switch it to kill.  I can switch it on and off and watch the voltage come and go.  I disconnected both safety switches on the brake and side stand and jumpered around them.   The brake light was staying on but I have since removed it as I have stripped all plastics off in order to trace wires.
There are ohm readings in the manual to measure between the two terminals of ignition coil and also from a terminal to the end of the plug wire.  Both tests are in spec.
The battery has been fully charged.  It is new but I keep it on a maintainer when i am not working on it.  The monitor does switch from charging to maintenance. 
The service manual provides an ohm reading spec between the two wires to the pick up at the stator.  It is within the spec.  Is there another test I should be considering?

Ordered and installed a new cdi tonight.  Still no spark.  Pretty much has me stumped.  Any ideas?

There are black/white wires on the other side of the frame.  They feed power to the cdi and the ignition coil.  They are fed by the ignition circuit fuse via the ignition switch.  I have battery voltage at all points along that black/white wire with key on and also when cranking the starter.   
It appears I still need to ohm test this exciter coil to eliminate the stator as a possibility.   If that is good then the only thing it appears it can be is the cdi box.
Of course nothing at this point can explain why this scooter ran with the plastics off and then I lost spark after putting it back together.  And now I have all plastic off and still no spark.

Still having trouble with this.  I did test the coil primary and secondary and both ohm tests are good.   The next step in the service manual is is to check the exciter coil resistance.  It tells me to check between the black/white terminal and ground.  I cannot find a black/white wire at the "A.C. Generator connector".  I went to the next step and that was to check the resistance of the pulser coil.  That checks ok.  Anybody have an idea where this black/white wire is?  There are the three yellow stator wires and the two for the pulser coil coming out of the right side of the engine near where the stator is located

Oh, one more thing.  Even though it was new, I had put the battery on a maintainer for 24hrs before trying it out

Engine turns over but no spark.   Here's a little background first.  The scooter has sat for 3 years due to health issues.  We're past those issues now so it's time to get it running again.  Even though it had stabilizer in the fuel, I pulled the fuel tank and drained the old fuel and added fresh.  I changed the spark plug, fuel filter, and air filter.  It started and ran on the center stand.  I changed engine and rear drive lube and ran it again on the center stand.  It started easily.
Then, I decided to do additional maintenance.  I replaced both tires, brake pads, changed the brake fluid, and coolant.  Replaced the battery.  Then I put all the plastics back on and now it won't start.
I lay the plug on the engine and crank it over but no spark.  I used vice grip pliers and clamped a heavy wire on the plug and grounded the other of the wire at the battery.  No spark.
I have jumpered past the rear brake switch and the side stand switch.  The fuses are good.  I have batt voltage at the red wire to voltage regulator.  I have battery voltage at the black/white wire at the coil.   I am not sure what I should have at the green wire to the coil.  The kill switch at the right grip will turn my test light off and on when checking at the coil.
Anybody have any ideas?
