I emailed Swampyankee (some may remember him here) and he was kind enough to fill me in on it.
Yes, in the manuals they call it either the ignition sensor or the pulse sensor. That's why I was having trouble finding it.
I had a suspicion that they were all one in the same but I wanted to be sure before I bought one.
BTW: My bike is proof that they don't ONLY act-up when the bike is warm/hot. My bike was running perfecty one evening. I parked it overnight in my garage and it refused to start the next day. I have a heated garage but the heat was turned-off, so the garage temperature was about 53 F.
Chilling the sensor with brake cleaner or something cold wasn't going to help it and only through a long process of elimination caused me to figure it had to be the ingintion sensor.
Replaced and set now - the bike started immediately and ran flawless again.
Oh well, now I have new plugs, oil, fuel filters, fuel lines, vacuum line, battery, a cleaned petcock valve, and everything else gone over with a fine toothed comb!
