I went out on Saturday for my first break-in ride on my new 872. At about 15 miles into the ride, my plugs fouled. When I pulled them, the PTO side was very gummy and black. The MAG side wasn't as bad but still a little dark. I put in new plugs and went on my way. Didn't foul any more plugs on the ride. Today I decided to pull the plugs and take a look. See the pics below for today's plugs. Left plug is PTO and right plug is MAG. What do you think??
Next question is, do you think the gummy plugs and fouling (super rich) can be attributed to me doing 3 heat cycles AND having extra oil in the tank? I am just curious.
I currently have a 560 in the PTO and 540 in the MAG. Running NGK BR9ECS plugs with 2 gallons of 100LL in the tank with 91 non-eth. Thanks for the input guys!!!
