The factory sets it pretty hot at 40, but at the same time this ensures a quick ignition, if anything, the included medium heat plug might wear out a little sooner. So, Isaac, you are right, one might dial that down a little, and it should still fire up quickly.
I personally have a surplus of medium hot plugs (Fox standard Long) and I dialed it down to 20 or there about and still fires up every time on the first attempt.
Have lots of fun with K-80s guys,
