Well, first thing to do is remove the spark plug and check the condition of the plug and if it sparks.

Not if the other three are firing. Each coil provides spark to 2 cylinders at the same time, as all of these bikes us a waste spark system.
You need to remove the plugs not necessarily to check the plugs, but to check to see if the cylinder is firing correctly, if there's any unusual buildup, etc. Eliminate as many variables as possible with actual data, not just hunches.

If your plug on #2 is sparking then you're going to need to get into the #2 carburetor (but clean them all since the carbs are out), something is probably blocking your pilot jet.

Could also be a loose plug cap.

Yea that problem could never happen on another bike. Who would think someone might do a search trying to find a answer to their problem. Would of been nice if the OP would have given a solved post, oh well. Then again maybe OP is in no hurry.

As if "Check your spark plug wire connections" is hard to come by advice.
