Good news part 1:  I got the tank molded today.  I boiled water in two of my wife's big soup pots and then poured the boiled water in the stainless steel sink in my utility room.  It works very well to heat the plastic to just the right temperature to mold it.  Once I got it where I wanted it, I just poured a little cold water on it. 

Good news part 2: I put the tank on it, and added oil, antifreeze/water, gas, and gave her a few kicks.  After about 4 kicks it lit right off. 

Bad news part 1: Unfortunately, I forgot to tighten my pipe mount up, so I had to kill it.  Once I got the pipe tightened back up, it wouldn't start again.  I pulled the spark plug and sure enough: no spark.  I tried a couple other new plugs I had, but no luck.  It still has compression and the fuel is flowing. 

Call for help part 1: Does anyone have any thoughts on where to start looking?  I checked all the connections and pulled the kill switch to make sure it wasn't stuck closed.  I just don't have much experience with checking the electrical systems.

Hope for the future part 1: While it was running, it sounded pretty stout.  I can't wait to ride it.

Thank you Sandblaster, that's a big help.  I'll bust out the ohm meter and get started.  If I have a bad part, can I use the CDI or coil from a 89 and up, or am I limited to 88 only?

sandblaster:
The coil is no problem.
You might be able to use the 88 CDI but I believe the timing is different.
I think the 89 and up max out at 19 degrees at 6K rpm
The 86-88 I think max out at 15 degrees
Someone hopefully can confirm
