If the one cyclinder is running and the rear is'nt, take the plug wire and connect it to another plug lay the plug on the head and start the bike. If the plug fires the problem is in the compression or fuel. If the bike is fuel injection ( yoiu did'nt list make year and model or engine size or even brand of engine, as they've Made harley davidsons since 1908. ) The fuel injection bikes like the V-Rod have an injector for each cyclinder you can exchange the two injectors ( they will fit and restart and see if the problem moves to the other cylinder. if it does you have a bad injector but the real poroblem sounds like you'ver overheated the reqar cylinder and the compression has gone away ( to check this remove the spark plug and put your finger over the spark plug hole ( make sure the plug wire is out of the way ( it'll shock you)) crank the engine and the cylindser compression should be enough to blow your finger off the hole. if not check the cylinder that does run and compare ( they should be the same) if theirs much difference then that cyclinder needs to be rebuilt.

The ignition is generated simultaneously in both cylinders: if you get it to a cylinder it means that the coil and the electronics pack is operational = the defect is located after them.
So replace the sparkplug - it might be shorted. If you still don't get spark then the spark wire for the rear one is interrupted - replace it.
