werkes exhaust

  1. Is this spark plug too lean or looks normal?

    hi, Please tell me your opinion on this spark plug I took out from Coil wire #6 closest to rear wheel. I only took out one spark plug for some other project, I didnt take out other spark plugs. Is this too Lean? Do I need to add fuel in the Penner map? Running Penner Map + Werkes Exhaust...
