I would check the cheap things first..ie the plugs. Ignition modules are usually bulletproof, cost a lot to replace, and being an electrical item may not be returnable.

Plugs fail for no apparent reason...just a fact.

Usually find my rear plug runs a little richer (carb), and turns a little darker than the the front. Switch them up every 3 or 4 rides, no issues!!!
