How can I check to see if my spark plugs are actually sparkin'?

best way is to take off the tank, pull a plug wire, stick a looooong screwdriver inside the boot (touching the metal), hold the screwdriver shaft about a 1/8th inch from the frame and turn it over. You'll see a nice blue/white spark if it's sparking good. -
The quick & dirty way (well not so dirty) that I have used is to just hook up an inductive timing light to each sparkplug lead one at a time & then crank it. If you get a flash then it's firing.
This will NOT tell you what condition the plug is in, etc., but you will know very quickly if it's sparking or not.
