VaKxRider:
Thanks for the replies everyone and I apologize for not responding sooner. I found why it would not start the next day. The choke plunger had now completely ceased to work but apparently everytime I would kick it over it would release on its own. My wife said I looked like Monkey Boy holding the choke up and kicking at the same time. (luckily I am rather tall and could pull this off).
As soon as I did that she fired right up. And I found the resistance specs in my manual and the both sides of the stator and the coil checked OK.
Now I am still having the same issue of it loading up at anything less than full throttle. After the rebuild I jetted to the specs on our jetting page but it still runs very rich (oil fowling  the plug severely).
Are the jet needles marked or do you have to measure them to determine what size you have? I am going to try and raise the clip first to see if that helps the situation at all. I have invested a lot of money into this bike and I want it to run the way it deserves to......

mikesmith:
There marked,I find the spec's are rich on the jetting page,its a good place to start though,better start rich than lean.Start leaning it out one thing at a time,like the clip. If its still rich below WFO try a leaner pilot ect,it takes time and trial and error to get it right so take notes on how it runs with the best jetting for the the time of the year(if you run pump gas its differnt for winter/summer)weather(humidity/temp/altitude)so you can go back to what works when you rejet for summer,differnt altitude ect.

Sharc:
If you got good gas and mix at 30-40:1, even 50:1, those jet specs should be real close. I'd be looking for carb problems, not jetting. You sure that choke is OK now...?

mikesmith:
I dont think the chokes a problem now or it wouldnt clean out at wide open,itd load up.
