Default Low RPM vibration when engine is under load

  • 2013 Z1000
  • All stock other than M4 slip-ons; no other performance modifiers
  • Almost 13k on the odometer
  • Still has original spark plugs
  • It is a very faint pulsing vibration, feels like it is come from down low on the bike, but not sure
  • Everything clears up above around 3000-3500 rpm
  • It doesn't seem to do it with the clutch pulled in.
  • It started the morning after a riding in a rain storm the night before

EDIT:
  • Mostly occurs below 2000 rpm
  • I can feel it mostly through the footpegs
  • Happens in 1st and 2nd but only below 2000-2500 rpm (I haven't tested higher gears yet)
  • Chain is lubed weekly

Any ideas? Thanks ahead of time.
