The main parts to the ignition electrics are , engine harness, ignition module, coil.
Some problems with twincam spark loss can be traced to crank position sensor faults. ignition module dead, coil dead, or loss of power to the coil .
Starting at the coil using a test light from earth, turn on the ignition and check the pins in the 3 wires to the coil, (twincam has 3, single fire, most Evos OEM is 2 wire Dual fire)
1 is power from ignition, the others are trigger wires to the module which opens and closes the connection,
If there is no power, then supply from the ignition wires in the harness has been interrupted, usually GREY from the fuse (check Fuse) to the handle bar harness on/off start buttons. White/black to the coil/module. later bike have a color change, get a manual if you can
if there is power then crank over the engine to check with the test light that the return wires to the module are turning on and off,
If this is happening and there is no spark at the coil then a good chance that your coil is stuffed,
If there is no on off of the test light then the crank position sensor should be replaced as a first action to eliminate it from the list. ( these can still work and be faulty at the same time)
The next test is to borrow a same year module from a buddy then plug and play to see if that works.
If you have not found the problem by now or you do not understand this explanation then you should not be playing with your Harley, please consult a trained Harley tech.
good luck.

The spark plug gap should be .040"
A Harley Davidson twin cam Fat Boy should be set with a gap of .40 inches. This is equal to 10 mm.
ALL Twin Cam engine plugs are a .040 gap
The valves on the twin cam are non-adjustable, they use hydraulic lifters.
There is NO WAY possible
Take it to your local Harley dealership.

The number of spark plugs is determined by the number of cylinders not the number of camshafts.

Can't Speak for all Twin Cams but on my 04 Heritage is between the shocks underneath the frame..
The Twin Cam 96B engine was released at the same time as the Twin Cam 96A model, for the 2007 model year, and is currently used on all Softail models.
